The Human Phenotype Ontology provides the following list of signs and symptoms for Charcot-Marie-Tooth disease type 1E. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Areflexia - Autosomal dominant inheritance - Childhood onset - Decreased motor nerve conduction velocity - Distal muscle weakness - Distal sensory impairment - Foot dorsiflexor weakness - Hammertoe - Hyporeflexia - Juvenile onset - Pes cavus - Sensorineural hearing impairment - Split hand - Steppage gait - Talipes calcaneovalgus - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. | What are the symptoms of Charcot-Marie-Tooth disease type 1E ? |

Hyperprolinemia type 2 results in an excess of a particular protein building block (amino acid), called proline, in the blood. This condition generally occurs when proline is not broken down properly by the body. Hyperprolinemia type 2 causes proline levels in the blood to be 10 to 15 times higher than normal, and it also causes high levels of a related compound called pyrroline-5-carboxylate. Some people with this condition develop mild mental retardation and seizures; however, the symptoms of this disorder vary in severity among affected individuals. | What is (are) Hyperprolinemia type 2 ? |

There is no specific treatment for hyperprolinemia type 2, even for those individuals who experience seizures. In general, if people with hyperprolinemia type 2 have symptoms, they are usually mild and do not require treatment. If seizures are present during childhood, they tend to disappear in adulthood. Attempts to reduce the amount of proline in an affected persons diet have resulted in only modest control of proline levels in the blood and have not reduced symptoms. | What are the treatments for Hyperprolinemia type 2 ? |

The Rh deficiency syndrome, also known as Rh-null syndrome, is a blood disorder where people have red blood cells (RBCs) lacking all Rh antigens. The Rh antigens maintain the integrity of the RBC membrane and therefore, RBCs which lack Rh antigens have an abnormal shape. There are two types of Rh deficiency syndrome: The regulator type is associated with many different changes (mutations) in the RHAG gene. The amorph type is caused by inactive copies of a gene (silent alleles) at the RH locus. As a result, the RBCs do not express any of the Rh antigens. The absence of the Rh complex alters the RBC shape, increases its tendency to break down (osmotic fragility), and shortens its lifespan, resulting in a hemolytic anemia that is usually mild. These patients are at risk of having adverse transfusion reactions because they may produce antibodies against several of the Rh antigens and can only receive blood from people who have the same condition. Rh deficiency syndrome is inherited in an autosomal recessive manner. Management is individualized according to the severity of hemolytic anemia. | What is (are) Rh deficiency syndrome ? |

Cylindromas are non-cancerous (benign) tumors that develop from the skin. They most commonly occur on the head and neck and rarely become cancerous (malignant). An individual can develop one or many cylindromas; if a person develops only one, the cylindroma likely occurred by chance and typically is not inherited. They usually begin to form during mid-adulthood as a slow-growing, rubbery nodule that causes no symptoms. The development of multiple cylindromas can be hereditary and is inherited in an autosomal dominant manner; this condition is called familial cylindromatosis. Individuals with the inherited form begin to develop many, rounded nodules of various size shortly after puberty. The tumors grow very slowly and increase in number over time. | What is (are) Dermal eccrine cylindroma ? |

Juvenile osteoporosis is a condition of bone demineralization characterized by pain in the back and extremities, multiple fractures, difficulty walking, and evidence of osteoporosis. Symptoms typically develop just before puberty. Osteoporosis is rare in children and adolescents. When it does occur, it is usually caused by an underlying medical disorder or by medications used to treat the disorder. This is called secondary osteoporosis. Sometimes, however, there is no identifiable cause of osteoporosis in a child. This is known as idiopathic osteoporosis. There is no established medical or surgical therapy for juvenile osteoporosis. In some cases, treatment is not necessary, as the condition resolves spontaneously. Early diagnosis may allow for preventive steps, including physical therapy, avoidance of weight-bearing activities, use of crutches and other supportive care. A well-balanced diet rich in calcium and vitamin D is also important. In severe, long-lasting cases, medications such as bisphosphonates may be used. In most cases, complete recovery of bone occurs. | What is (are) Juvenile osteoporosis ? |

Chilaiditi syndrome is a medical condition in which a portion of the colon is abnormally positioned between the liver and the diaphragm. Symptoms vary, but may include abdominal pain, nausea, vomiting, and small bowel obstruction. In many cases, there are no symptoms and the interposition is an incidental finding. When no symptoms are present, the clinical finding is called Chilaiditis sign. . The underlying cause of Chilaiditi syndrome is unknown. Treatment is symptomatic and supportive. | What is (are) Chilaiditi syndrome ? |
|
The symptoms of Chilaiditi syndrome vary. Chronic recurrent abdominal pain is a common finding. Other symptoms might include nausea, vomiting, constipation, indigestion, difficulty swallowing, and abdominal tenderness, especially in the upper, central area. In some cases, breathing problems may develop. | What are the symptoms of Chilaiditi syndrome ? |
|
The exact cause of Chilaiditi syndrome is unknown. The condition appears to occur with higher frequency among individuals with chronic lung disease, scarring of the liver (cirrhosis), and in those with an accumulation of ascites in the abdomen. Other risk factors may include reduced liver volume, paralysis of the motor nerve to the diaphragm (phrenic nerve palsy), and obesity. In some cases, the condition is present from birth (congenital). | What causes Chilaiditi syndrome ? |
|
Treatment of Chilaiditi syndrome is directed at the individual symptoms present. In some cases, treatment is not needed. Reducing (or removing) the pressure within the abdomen may help alleviate symptoms. This may be achieved through conservative measure that address constipation, pain and distention. Surgical intervention may include removal of a portion of the color or the anchoring of the liver to the abdominal wall. | What are the treatments for Chilaiditi syndrome ? |

Familial hypercholesterolemia is a condition characterized by very high levels of cholesterol in the blood due to mutations in the LDLR gene. People with hypercholesterolemia have a high risk of developing a form of heart disease called coronary artery disease, as well as health problems related to the buildup of excess cholesterol in other tissues (e. g. , in the tendons and skin). Familial hypercholesterolemia tends to be passed through families in an autosomal dominant fashion. There are other hereditary forms of hypercholesterolemia caused by mutations in the APOB, LDLRAP1, or PCSK9 gene. However, most cases of high cholesterol are not caused by a single inherited condition, but result from a combination of lifestyle choices and the effects of variations in many genes. | What is (are) Familial hypercholesterolemia ? |

Signs and symptoms in individuals with the autosomal dominant form of familial hypercholesterolemia (FH), also called the heterozygous form, may include: Men who have FH may have heart attacks in their 40s to 50s, and 85% of men with the disorder have a heart attack by age 60. Affected women may have heart attacks in their 50s and 60s. Individuals with the rare, autosomal recessive form of FH (also called homozygous FH) develop xanthomas beneath the skin over their elbows, knees and buttocks as well as in the tendons at a very early age, sometime in infancy. In individuals with this form of FH, heart attacks and/or death may occur before age 30, sometimes in young children if they are not aggressively treated.

Familial hypercholesterolemia (FH) is usually inherited in an autosomal dominant manner (in which case it is referred to as heterozygous FH). Individuals inherit two copies of each gene (one from each parent). In an autosomal dominant condition, having only one abnormal (mutated) copy of the gene is sufficient to cause the condition. In most cases the mutated gene is inherited from an affected parent, but it is possible for the mutation to occur for the first time in the affected individual. An individual with an autosomal dominant condition has a 50% (1 in 2) chance to pass the mutation on to each of his/her children and a 50% chance to not pass on the mutation. More rarely, familial FH may be inherited in an autosomal recessive manner. This occurs when an individual inherits a mutated copy of the gene from both parents (this is also called homozygous FH). This is a much more severe form of FH. An individual with this form of FH will always pass on a mutated copy of the gene, and therefore each of his/her children will have heterozygous FH. | Is Familial hypercholesterolemia inherited ? |

The overall goal of treatment for familial hypercholesterolemia (FH) is to lower the risk for atherosclerosis (build-up of plaque in the arteries) by lowering the LDL cholesterol levels in the blood stream. The first step in treatment for individuals with the heterozygous form (also called the autosomal dominant form) is changing the diet to reduce the total amount of fat eaten. This may be accomplished by limiting the amount of beef, pork, and lamb in the diet; cutting out butter, whole milk, fatty cheeses and oils; and eliminating egg yolks, organ meats and other sources of saturated fat from animals. Dietary counseling is often recommended to help individuals change their eating habits. Exercise and weight loss may also help in lowering cholesterol levels. Drug therapy is also often necessary lifestyle changes may not be enough to lower cholesterol levels. Several different cholesterol-lowering medications may be used alone or in combination; they may include statins, bile acid sequestrants, ezetemibe, niacin, gemfibrozil, and fenofibrate. Individuals with the more severe, homozygous form of FH (also called the autosomal recessive form) need more aggressive therapies to treat their significantly elevated levels of cholesterol. Drug therapy is often not effective enough at lowering LDL cholesterol levels. Therefore, individuals with this form may need periodical LDL apheresis, a procedure that removes LDL from the blood. In some cases, major surgery such as a liver transplant is necessary. | What are the treatments for Familial hypercholesterolemia ? |

Werners syndrome is a disease chiefly characterized by premature aging and cancer predisposition. Development is typically normal until the end of the first decade; the first sign is the lack of a growth spurt during puberty. Early signs (usually in the 20s) include loss and graying of hair, hoarseness, and scleroderma-like skin changes, followed by cataracts, type 2 diabetes mellitus, hypogonadism, skin ulcers, and osteoporosis in the 30s. Myocardial infarction (heart attack) and cancer are the most common causes of death, which typically occurs in the late 40s. It is caused by mutations in the WRN gene and is inherited in an autosomal recessive manner. Management focuses on treatment of signs and symptoms and prevention of secondary complications. | What is (are) Werners syndrome ? |

Unverricht-Lundborg disease is an inherited form of progressive myoclonus epilepsy that is characterized by episodes of involuntary muscle jerking or twitching (myoclonus) that increase in frequency and severity over time. Episodes of myoclonus may be brought on by physical exertion, stress, light, or other stimuli. Affected individuals usually begin showing signs and symptoms of the disorder between the ages of 6 and 15. Over time, the myoclonic episodes may become severe enough to interfere with walking and other everyday activities. Other features include seizures involving loss of consciousness, muscle rigidity, and convulsions (tonic-clonic or grand mal seizures). Like the myoclonic episodes, these may increase in frequency over several years but may be controlled with treatment. After several years of progression, the frequency of seizures may stabilize or decrease. Unverricht-Lundborg disease is caused by mutation in the CSTB gene. It is inherited in an autosomal recessive pattern. | What is (are) Unverricht-Lundborg disease ? |

Chromosomes are the structures found in every cell of the body that contain our DNA, the instructions that tell our body what to do. Humans have 23 pairs of chromosomes, which means that each human cell contains 46 chromosomes. Each chromosome has a p and q arm; p is the short arm and q is the long arm. The p arm is always on the top and the q arm is on the bottom. Chromosome 9 inversion is when there are two breaks on chromosome 9. The segment between the breakpoints flips around and reinserts back into the same place on chromosome 9. If both breaks occur in the same arm of the chromosome, this is called a paracentric inversion. If one break occurs in the short arm and the other in the long arm of the chromosome, then this is called a pericentric inversion. Chromosome 9 inversions commonly occur as a pericentric inversion. | What is (are) Chromosome 9 inversion ? |

Anophthalmia plus syndrome (APS) is a very rare syndrome that involves malformations in multiple organs of the body. The most common findings in affected individuals are anophthalmia (absence of one or both eyes) or severe microphthalmia (abnormally small eyes), and cleft lip and/or cleft palate. Other findings may include wide-set eyes (hypertelorism); low-set ears; narrowed or blocked nasal passages (choanal stenosis or atresia); sacral neural tube defect, midline abdominal wall defects, clinodactyly, eye colobomas and congenital glaucoma. It has been suggested that APS is inherited in an autosomal recessive manner, although the genetic cause has not yet been identified. | What is (are) Anophthalmia plus syndrome ? |

Anophthalmia plus syndrome (APS) may involve malformations in multiple organs of the body including the eyes, ears, nose, face, mouth, brain, sacral vertebrae, meninges (tissue that lines the outer part of the brain and spinal cord), abdominal wall, heart, digits (fingers and toes), and endocrine system. Based on the few cases reported in the literature, it appears that all affected individuals have had anophthalmia (absence of one or both eyes) and/or microphthalmia (abnormally small eyes). It has also been estimated that approximately 89% of affected individuals have had an oral-facial cleft (such as cleft lip and/or cleft palate). Other specific findings that have been reported in more than one affected individual include wide-set eyes (hypertelorism), low-set ears, choanal stenosis or atresia (narrowing or blockage of the nasal passages), sacral neural tube defect, midline abdominal wall defects, clinodactyly (abnormally bent or curved finger), eye colobomas, and congenital glaucoma. There have been other, additional abnormalities that have only been reported in single individuals.

A review of the available medical literature does not currently yield information about specific diagnostic criteria for anophthalmia plus syndrome (APS). Because APS is so rarely reported, specific diagnostic criteria may not exist. Anophthalmia and/or microphthalmia with oral-facial clefting occurs in a number of known syndromes; however, the other known syndromes typically have specific other features (such as limb abnormalities, deafness or other organ anomalies). A diagnosis of APS may be considered when an individual has the signs and symptoms most commonly reported in affected individuals, but other known syndromes with overlapping features have been ruled out. | How to diagnose Anophthalmia plus syndrome ? |

Ewing sarcoma is a malignant (cancerous) bone tumor that affects children. It can occur any time during childhood and young adulthood, but usually develops during puberty, when bones are growing rapidly. The tumor may arise anywhere in the body, usually in the long bones of the arms and legs, the pelvis, or the chest. It may also develop in the skull or the flat bones of the trunk. There are few symptoms. The most common is pain and occasionally swelling at the site of the tumor. Fever may also be present. The tumor often spreads (metastasis) to the lungs and other bones. The cause of Ewing sarcoma is unknown. Most cases are thought to occur randomly and many involved a reciprocal translocation between chromosomes 11 and 22. Treatment depends upon a number of factors, but may include chemotherapy, radiation and/or surgical interventions. | What is (are) Ewing sarcoma ? |

The exact cause of Ewing sarcoma remains largely unknown. Chromosomal studies have found that Ewing sarcoma cells are often characterized by an abnormal change in their genetic makeup known as a reciprocal translocation. The most common mutation, occurring in approximately 85% of Ewing sarcoma tumors, involves two genes, the EWSR1 gene on chromosome 22 and the FLI1 gene on chromosome 11. This rearrangement of genetic material between chromosomes 22 and 11 fuses part of the EWSR1 gene with part of the FLI1 gene, creating the EWSR1/FLI1 fusion gene. This mutation is acquired during a persons lifetime and is present only in tumor cells. This type of genetic change, called a somatic mutation, is not inherited. In extremely rare cases, Ewing sarcoma may develop as a second malignancy, which means that the condition develops as a late-onset complication of earlier treatment for another form of cancer. | What causes Ewing sarcoma ? |
|
This condition is generally not inherited but arises from a mutation in the bodys cells that occurs after conception (somatic mutation). Most cases are considered to be sporadic. However, the incidence of neuroectodermal and stomach malignancies is increased among family members of patients with tumors of the Ewing sarcoma family. A search of the medical literature did identify a very small number of cases of Ewing sarcoma among siblings. To access articles on this topic, click here. | Is Ewing sarcoma inherited ? |

Potocki-Lupski syndrome (PTLS) is a genetic disorder characterized by the presence of an extra copy of a tiny portion of chromosome 17 (duplication of 17p11. 2). People with this duplication often have low muscle tone, poor feeding, and failure to thrive during infancy. They may also present with delayed development of motor and verbal milestones. In addition, many individuals display some behaviors commonly associated with autism spectrum disorders. While most cases of Potocki-Lupski syndrome occur sporadically, in rare cases, it may be inherited. Treatment involves physical, occupational, and speech therapy. | What is (are) Potocki-Lupski syndrome ? |

Lennox-Gastaut syndrome is a form of severe epilepsy that begins in childhood. It is characterized by multiple types of seizures and intellectual disability. This condition can be caused by brain malformations, perinatal asphyxia (lack of oxygen), severe head injury, central nervous system infection and inherited degenerative or metabolic conditions. In about one-third of cases, no cause can be found. Treatment for Lennox-Gastaut syndrome includes anti-epileptic medications such as valproate, lamotrigine, felbamate, or topiramate. There is usually no single antiepileptic medication that will control seizures. Children may improve initially, but many later show tolerance to a drug or develop uncontrollable seizures. | What is (are) Lennox-Gastaut syndrome ? |

Alopecia universalis (AU) is a condition characterized by the complete loss of hair on the scalp and body. It is an advanced form of alopecia areata, a condition that causes round patches of hair loss. Although the exact cause of AU is unknown, it is thought to be an autoimmune condition in which an affected persons immune system mistakenly attacks the hair follicles. Roughly 20% of affected people have a family member with alopecia, suggesting that genetic factors may contribute to the development of AU. There is currently no cure for AU, but sometimes hair regrowth occurs on its own, even after many years. | What is (are) Alopecia universalis ? |

Alopecia universalis (AU) is characterized by the complete loss of hair on both the scalp and body. Most people with AU do not have other signs and symptoms, but some may experience a burning sensation or itching on affected areas. In some cases, AU can be associated with other conditions such as atopic dermatitis, thyroid disorders, and/or nail changes (such as pitting). Anxiety, personality disorders, depression, and paranoid disorders are more common in people with different forms of alopecia areata.

The exact underlying cause of alopecia universalis (AU) is not currently known. AU is an advanced form of alopecia areata (AA), a condition that leads to round patches of hair loss. AA is thought to be an autoimmune condition in which an affected persons immune system mistakenly attacks the hair follicles. Genetic studies have found that AA and AU are associated with several immune-related genes; however, they are likely complex disorders caused by the interaction of multiple genetic and environmental factors. This means that even if someone inherits a genetic predisposition to the condition, they may not become affected unless something in the environment triggers the onset of the condition. | What causes Alopecia universalis ? |
|
Alopecia universalis is believed to be a multifactorial condition, which means it is caused by a combination of environmental influences and genetic predisposition. While a predisposition can be inherited and some affected people have a family history, the condition itself is not thought to be inherited. | Is Alopecia universalis inherited ? |
|
A diagnosis of alopecia universalis is usually based on the signs and symptoms present in each person. In rare cases, a scalp biopsy may be needed to confirm the diagnosis. | How to diagnose Alopecia universalis ? |
|
Although these is no therapy approved for the treatment of alopecia universalis, some people find that medications approved for other purposes may help hair grow back, at least temporarily. Since alopecia universalis is one of the more severe types of alopecia areata, treatment options are somewhat limited. The most common treatments include corticosteriods and topical (applied to the skin) immunotherapy. There are possible side effects of corticosteriods which should be discussed with a physician. Also, regrown hair is likely to fall out when the corticosteriods are stopped. About 40% of people treated with topical immunotherapy will regrow scalp hair after about six months of treatment. Those who do successfully regrow scalp hair need to continue the treatment to maintain the hair regrowth. While these treatments may promote hair growth, they do not prevent new loss or cure the underlying disease. For those who do not respond to treatment, wigs are an option. | What are the treatments for Alopecia universalis ? |

Mnires disease is an abnormality of the inner ear. Signs and symptoms may include disabling vertigo or severe dizziness lasting from minutes to hours; tinnitus or a roaring sound in the ears; fluctuating hearing loss; and the sensation of pressure or pain in the affected ear. A small percentage of people have drop attacks, also called spells of Tumarkin. The disorder usually affects only one ear and is a common cause of hearing loss. Some people develop symptoms in both ears many years after their initial diagnosis. The exact cause of Mnires disease is unknown, but the symptoms are thought to be associated with a change in fluid volume within a portion of the inner ear known as the labyrinth. Treatment may include medications or surgery depending on the severity of the condition. | What is (are) Mnires disease ? |

The symptoms of Mnires disease typically occur suddenly and can arise daily, or as infrequently as once a year. Vertigo, often the most debilitating symptom of Mnires disease, typically involves a whirling dizziness that forces the affected person to lie down. Vertigo attacks can lead to severe nausea, vomiting, and sweating, and often come with little or no warning. Some people with Mnires disease have attacks that start with tinnitus (ear noises), a loss of hearing, or a full feeling or pressure in the affected ear. It is important to remember that all of these symptoms are unpredictable. Typically, the attack is characterized by a combination of vertigo, tinnitus, and hearing loss lasting several hours. People experience these discomforts at varying frequencies, durations, and intensities. Some may feel slight vertigo a few times a year. Others may be occasionally disturbed by intense, uncontrollable tinnitus while sleeping. Affected people may also notice hearing loss or feel unsteady for prolonged periods. Other occasional symptoms of Mnires disease may include headaches, abdominal discomfort, and diarrhea. A persons hearing tends to recover between attacks but over time may become worse. Menieres disease usually starts in one ear but it may extend to involve both ears over time. The Human Phenotype Ontology provides the following list of signs and symptoms for Mnires disease. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Autosomal dominant inheritance - Hearing impairment - Tinnitus - Vertigo - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. | What are the symptoms of Mnires disease ? |

The underlying cause of Mnires disease is unknown, although it probably results from a combination of environmental and genetic factors. Possible factors that have been studied include viral infections; trauma to the middle ear; middle ear infection (otitis media); head injury; a hereditary predisposition; syphilis; allergies; abnormal immune system responses; migraines; and noise pollution. The symptoms of Mnires disease are thought to relate to changes in fluid volume in the inner ear, which contains structures necessary for normal hearing and balance. Changes in fluid volume may disrupt signals sent from the inner ear to the brain, or may lead to tears or ruptures of the structures that affect hearing and balance. More detailed information about the causes of symptoms associated with Mnires disease is available on NIDCDs Web site. | What causes Mnires disease ? |

The hallmark of Mnires disease is the fluctuation, waxing and waning of symptoms. Proper diagnosis of Mnires disease entails several procedures, including a medical history interview; a physical examination; hearing and balance tests; and medical imaging with magnetic resonance imaging (MRI). Accurate measurement and characterization of hearing loss are of critical importance in the diagnosis of Mnires disease. Through the use of several types of hearing tests, physicians can characterize hearing loss as being sensory (arising from the inner ear) or neural (arising from the hearing nerve). Recording the auditory brain stem response, which measures electrical activity in the hearing nerve and brain stem, is useful in differentiating between these two types of hearing loss. Electrocochleography, recording the electrical activity of the inner ear in response to sound, helps confirm the diagnosis. To test the vestibular or balance system, physicians irrigate the ears with warm and cool water or air. This procedure, known as caloric testing, results in nystagmus, rapid eye movements that can help a physician analyze a balance disorder. Since tumor growth can produce symptoms similar to Mnires disease, an MRI is a useful test to determine whether a tumor is causing the patients vertigo and hearing loss. | How to diagnose Mnires disease ? |

At the present time there is no cure for Mnires disease, but there are several safe and effective medical and surgical therapies that are available to help individuals cope with the symptoms. The symptoms of the disease are often controlled successfully by reducing the bodys retention of fluids through dietary changes (such as a low-salt or salt-free diet and no caffeine or alcohol). Medications such as antihistamines, anticholinergics, and diuretics may lower endolymphatic pressure by reducing the amount of endolymphatic fluid. Eliminating tobacco use and reducing stress levels may also help lessen the severity of symptoms. Symptoms such as dizziness, vertigo, and associated nausea and vomiting may respond to sedative/hypnotics, benzodiazepines like diazepam and anti-emetics. Different surgical procedures are an option for individuals with persistent, debilitating vertigo. Labyrinthectomy (removal of the inner ear sense organ) can effectively control vertigo, but sacrifices hearing and is reserved for patients with nonfunctional hearing in the affected ear. Vestibular neurectomy, selectively severing a nerve from the affected inner ear organ, usually controls the vertigo while preserving hearing but carries surgical risks. Recently, the administration of the ototoxic antibiotic gentamycin directly into the middle ear space has gained popularity worldwide for the control of vertigo associated with Mnires disease. An article published in the journal Lancet in August 2008, written by Sajjadi and Paparella, reviews treatment options and strategies for individuals with Mnires disease.

Keratosis follicularis spinulosa decalvans (KFSD) is a rare, inherited, skin condition. KFSD is a form of ichthyoses, a group of inherited conditions of the skin in which the skin tends to be thick and rough, and to have a scaly appearance. The face, neck, and forearms are frequently involved. The thickening of the skin is accompanied by the loss of eyebrows, eyelashes, and hair on the face and head. Allergic reactions (atopy), reduced tolerance of bright light (photophobia), and inflammation of the eyes cornea (keratitis) may also occur. KFSD is thought to be caused by mutations in the SAT1 gene and inherited in an X-linked manner. | What is (are) Keratosis follicularis spinulosa decalvans ? |

Sudden infant death syndrome (SIDS) is the unexpected, sudden death of a child under age 1 which cannot be explained after a thorough investigation is conducted. Infants who are affected by the condition generally appear healthy with no suspicious signs and symptoms prior to the incident. It is the leading cause of death in infants age 1 to 12 months old. The exact underlying cause of SIDS is unknown; however, scientists suspect that it is likely a multifactorial condition (associated with the effects of multiple genes in combination with lifestyle and environmental factors). Although there is no guaranteed way to prevent SIDS, the American Academy of Pediatrics has a published list of recommendations for risk reduction.

Baller-Gerold syndrome is a rare condition characterized by the premature fusion of certain skull bones (craniosynostosis) and abnormalities of bones in the arms and hands, sometimes referred to as radial ray anomalies. Many cases of Baller-Gerold syndrome are caused by mutations in the RECQL4 gene. These cases are inherited in an autosomal recessive manner. In a few reported cases, the characteristic features of Baller-Gerold syndrome have been associated with prenatal exposure to a drug called sodium valproate which is used to treat epilepsy and certain psychiatric disorders. Treatment may include surgery for treatment of craniosynostosis or reconstruction of the index finger to functional thumb. The symptoms of Baller-Gerold syndrome overlap with features of Rothmund-Thomson syndrome and RAPADILINO syndrome which are also caused by the RECQL4 gene. Researchers are trying to determine if these conditions are separate disorders or part of a single syndrome with overlapping signs and symptoms. | What is (are) Baller-Gerold syndrome ? |

Many people with Baller-Gerold syndrome have prematurely fused skull bones along the coronal suture, the growth line that goes over the head from ear to ear. Other parts of the skull may be malformed as well. These changes result in an abnormally shaped head, a prominent forehead, and bulging eyes with shallow eye sockets (ocular proptosis). Other distinctive facial features can include widely spaced eyes (hypertelorism), a small mouth, and a saddle-shaped or underdeveloped nose. Bone abnormalities in the hands include missing fingers (oligodactyly) and malformed or absent thumbs. Partial or complete absence of bones in the forearm is also common. Together, these hand and arm abnormalities are called radial ray malformations. People with Baller-Gerold syndrome may have a variety of additional signs and symptoms including slow growth beginning in infancy, small stature, and malformed or missing kneecaps (patellae). A skin rash often appears on the arms and legs a few months after birth. This rash spreads over time, causing patchy changes in skin coloring, areas of skin tissue degeneration, and small clusters of enlarged blood vessels just under the skin. These chronic skin problems are collectively known as poikiloderma. The Human Phenotype Ontology provides the following list of signs and symptoms for Baller-Gerold syndrome.

Factor V Leiden thrombophilia is an inherited disorder that results in an increased risk of developing abnormal blood clots. Factor V Leiden is the name of a specific gene mutation in the F5 gene. This gene plays a critical role in the normal formation of blood clots in response to an injury. People can inherit one or two copies of the factor V Leiden gene mutation. Those who inherit one copy are called heterozygotes. People who inherit two copies of the mutation, one from each parent, are called homozygotes. Having the factor V Leiden mutation increases your risk for developing a clot in your legs called a deep venous thrombosis (DVT). It also increases your risk of developing a clot that travels through the bloodstream and lodges in the lungs, called a pulmonary embolism (PE). | What is (are) Factor V Leiden thrombophilia ? |
|
Individuals affected by factor V Leiden thrombophilia have an increased risk of developing blood clots. The severity of factor V Leiden thrombophilia is extremely variable. Many individuals with the factor V Leiden allele never develop a blood clot. Although most individuals with factor V thrombophilia do not experience their first thrombotic event until adulthood, some have recurrent thromboembolism before age 30 years. The chance a person will develop a blood clot is affected by the number of factor V Leiden mutations, the presence of coexisting genetic abnormalities, and non-genetic risk factors. Non-genetic risk factors include surgery, long periods of not moving (like sitting on a long airplane ride), birth control pills and other female hormones, childbirth within the last 6 months, and traumas or fractures. Individuals who inherit one copy of the factor V Leiden mutation have a fourfold to eightfold increase in the chance of developing a clot. Homozygotes (people who inherit two factor V Leiden mutations) may have up to 80 times the usual risk of developing a blood clot. Considering that the risk of developing an abnormal blood clot averages about 1 in 1,000 per year in the general population, the presence of one copy of the factor V Leiden mutation increases that risk to 4 to 8 in 1,000, and having two copies of the mutation may raise the risk as high as 80 in 1,000. People with factor V Leiden have an increased chance of having a blood clot that forms in large veins in the legs (deep venous thrombosis, or DVT) or a clot that travels through the bloodstream and lodges in the lungs (pulmonary embolism, or PE). Symptoms of deep vein thrombosis usually include leg pain, tenderness, swelling, increased warmth or redness in one leg. The symptoms of pulmonary embolism usually include cough, chest pain, shortness of breath or rapid heartbeat or breathing.

Factor V Leiden thrombophilia is caused by a specific mutation in the Factor V gene. Factor V plays a critical role in the formation of blood clots in response to injury. Genes are our bodys instructions for making proteins. The factor V gene instructs the body how to make a protein called coagulation factor V. Coagulation factor V is involved in a series of chemical reactions that hold blood clots together. A molecule called activated protein C (APC) prevents blood clots from growing too large by inactivating factor V. | What causes Factor V Leiden thrombophilia ? |
|
Factor V Leiden is a genetic condition and can be inherited from a parent. It is important to understand that each person inherits two copies of every gene, one from their mother and the other copy from their father. Individuals who inherit one copy of the factor V Leiden mutation from a parent are called heterozygotes. Heterozygotes have a 50% chance with each pregnancy of passing the mutated gene to their offspring (and therefore they also have a 50% chance of having a child who does not inherit the gene mutation). People who inherit two copies of the mutation, one from each parent, are called homozygotes. Homozygotes will always pass one copy of the mutated gene to their offspring. If both parents are heterozygotes (carry one factor V Leiden mutation) than they would have a 25% chance of having a child with two factor V Leiden mutations, a 25% chance of having a child with no mutations, and a 50% chance of having a child with one mutation. | Is Factor V Leiden thrombophilia inherited ? |

No clinical features (signs and/or symptoms) are specific for factor V Leiden thrombophilia. The diagnosis of factor V Leiden thrombophilia requires a coagulation screening test or DNA analysis of F5, the gene for factor V, to identify the specific mutation that causes this condition. The APC (activated protein C) resistance assay, a coagulation screening test, measures the anticoagulant response to APC. This screening test has a sensitivity and specificity for factor V Leiden approaching 100%. The sensitivity of a test is a measure of the tests ability to detect a positive result when someone has the condition, while the specificity is a measure of the tests ability to identify negative results. Targeted mutation analysis (a type of DNA test) of the F5 gene for the Leiden mutation is considered definitive and has a mutation detection frequency of approximately 100%. This means that approximately all individuals who have the factor V Leiden mutation will be detected by this genetic test. It is generally recommended that individuals who test positive by another means should then have the DNA test both for confirmation and to distinguish heterozygotes (individuals with a mutation in one copy of the gene) from homozygotes (individuals with mutations in both copies of the gene). | How to diagnose Factor V Leiden thrombophilia ? |

The management of individuals with factor V Leiden depends on the clinical circumstances. People with factor V Leiden who have had a deep venous thrombosis (DVT) or pulmonary embolism (PE) are usually treated with blood thinners, or anticoagulants. Anticoagulants such as heparin and warfarin are given for varying amounts of time depending on the persons situation. It is not usually recommended that people with factor V Leiden be treated lifelong with anticoagulants if they have had only one DVT or PE, unless there are additional risk factors present. Having had a DVT or PE in the past increases a persons risk for developing another one in the future, but having factor V Leiden does not seem to add to the risk of having a second clot. In general, individuals who have factor V Leiden but have never had a blood clot are not routinely treated with an anticoagulant. Rather, these individuals are counseled about reducing or eliminating other factors that may add to ones risk of developing a clot in the future. In addition, these individuals may require temporary treatment with an anticoagulant during periods of particularly high risk, such as major surgery. Factor V Leiden increases the risk of developing a DVT during pregnancy by about seven-fold. Women with factor V Leiden who are planning pregnancy should discuss this with their obstetrician and/or hematologist. Most women with factor V Leiden have normal pregnancies and only require close follow-up during pregnancy. For those with a history of DVT or PE, treatment with an anticoagulant during a subsequent pregnancy can prevent recurrent problems. | What are the treatments for Factor V Leiden thrombophilia ? |

Schwartz Jampel syndrome type 1 (SJS1) is a genetic disorder that affects bone and muscle development. Signs and symptoms may include muscle weakness and stiffness, abnormal bone development, joint contractures, short stature, small, fixed facial features, and eye abnormalities (some of which may impair vision). SJS1 can be divided into two subtypes differentiated by severity and age of onset. Type 1A, considered classic SJS, is the most commonly recognized type. Individuals with type 1A typically develop more mild symptoms later in childhood, while individuals with type 1B have symptoms that are more severe and are apparent immediately after birth. SJS1 is caused by mutations in the HSPG2 gene which makes a protein called perlecan. SJS1 is thought to be inherited in an autosomal recessive manner; however, some cases reported in the medical literature suggest an autosomal dominant inheritance pattern. Treatment for both type 1A and 1B aims to normalize muscle activity through various methods including massage and stretching, medications such as Botulinum toxin, and surgery. There is a more severe, distinct condition called Stuve-Wiedemann syndrome which is caused by mutations in the LIFR gene. At one time cases of Stuve-Wiedemann syndrome were referred to as Neonatal Schwartz Jampel syndrome type 2.

Individuals with Schwartz-Jampel syndrome type 1 (SJS1) have characteristic facial features, muscle weakness (hypotonia), and muscle stiffness (myotonia). Facial features of individuals with SJS1 can seem fixed in the same expression with puckered lips due to weakening and stiffening of the facial muscles. Additional facial features may include: Blepharophimosis (narrowing of the eye opening) Epicanthal folds (skin fold of the upper eyelid covering the inner corner of the eye) Blepharospasm (involuntary blinking or spasm of the eyelids) Hypertrichosis (excessive hair) of the eye lashes Micrognathia (small lower jaw) Individuals with SJS1 usually have short stature. Other skeletal and joint findings may include: Shortened neck Pectus carinatum (outward bowing of the chest) Kyphosis (curving of the spine that causes a bowing or rounding of the back) Coxa valga (hip deformity involving an increased neck-shaft angle of the femur) Joint contractures Osteoporosis Widening of the metaphysis (portion of the bone containing the growth plate) Delayed bone age Other less common symptoms include: a high pitched voice, bilateral carpel tunnel syndrome, and malignant hyperthermia. One study suggested that as many as 20% of individuals with SJS1 have an intellectual disability; however, most individuals with SJS1 have normal intelligence.

Schwartz Jampel syndrome type 1 (SJS1) is caused by mutations in the HSPG2 gene. The HSPG2 gene codes for the protein perlecan, which is found in muscle and cartilage. Although the role of the perlecan protein is not fully understood, it is thought to play an essential role in many biological activities such as cell signaling and cellular structure. In SJS1, it is suspected that a disturbance in perlecan function leads to a deficiency of acetylcholinesterase, an enzyme involved in breaking down acetylcholine, a neurotransmitter that sends messages between nerves, leading to muscle contraction. If acetylcholine is not broken down, it may lead to an prolonged muscle contraction or stiffening of the muscles (myotonia). | What causes Schwartz Jampel syndrome type 1 ? |

The majority of cases of Schwartz Jampel syndrome type 1 (SJS1) are inherited in an autosomal recessive pattern. This means that to have the disorder, a person must have a mutation in both copies of the responsible gene in each cell. Individuals with SJS1 inherit one mutated copy of the gene from each parent, who is referred to as a carrier. Carriers of an autosomal recessive condition typically do not have any signs or symptoms (they are unaffected). Rarely, cases of SJS1 with autosomal dominant inheritance have been reported. This means that having a change (mutation) in only one copy of the responsible gene in each cell is enough to cause features of the condition. | Is Schwartz Jampel syndrome type 1 inherited ? |

The diagnosis of Schwartz Jampel syndrome type 1 (SJS1) is suspected based on clinical findings including characteristic facial features, skeletal features, and muscle stiffness (myotonia). Studies that may be useful in diagnosing SJS1 include: blood tests (which may show elevated serum creatine kinase or adolase); imaging studies; muscle biopsy; and electromyography (EMG)/nerve conduction studies. Genetic testing of the HSPG2 gene may additionally be helpful to confirm the diagnosis. | How to diagnose Schwartz Jampel syndrome type 1 ? |

Treatment of Schwartz Jampel syndrome type 1 (SJS1) aims to reduce stiffness and cramping of muscles. This might include nonpharmacologic modalities such as massage, warming of muscles, and gradual strengthening exercises. Medications that might be utilized include muscle relaxants and anti seizure medications, particularly Carbamazepine. Botox might additionally be used to relieve eye symptoms such as blepharospasm (involuntary blinking of spasm of eyes). If Botox is not successful in managing eye symptoms, a variety of surgical techniques have been found to be effective. When considering surgery as an option, an important consideration is the risk for malignant hyperthermia, which could lead to adverse outcomes. | What are the treatments for Schwartz Jampel syndrome type 1 ? |

Medullary cystic kidney disease (MCKD) is a chronic, progressive kidney disease characterized by the presence of small renal cysts that eventually lead to end stage renal failure. Symptoms typically appear at an average age of 28 years and may include polyuria (excessive production or passage of urine) and low urinary osmolality (decreased concentration) in the first morning urine. Later, symptoms of renal insufficiency typically progress to include anemia, metabolic acidosis and uremia. End stage renal disease (ESRD) eventually follows. There are 2 types of MCKD, which are both inherited in an autosomal dominant manner but are caused by mutations in different genes. MCKD 1 is caused by mutations in the MCKD1 gene (which has not yet been identified) and MCKD 2 is caused by mutations in the UMOD gene. The 2 types also differ by MCKD 1 being associated with ESRD at an average age of 62 years, while MCKD 2 is associated with ESRD around 32 years and is more likely to be associated with hyperuricemia and gout. Treatment for MCKD may include correction of water and electrolyte imbalances, and dialysis followed by renal transplantation for end-stage renal failure. | What is (are) Medullary cystic kidney disease 1 ? |

Asperger syndrome (AS) is an autism spectrum disorder, a type of neurological condition characterized by impaired language and communication skills, and repetitive or restrictive thought and behavior patterns. Unlike many people with autism, those with AS retain their early language skills. Features of AS include an obsessive interest in a particular object or topic; high vocabulary; formal speech patterns; repetitive routines or habits; inappropriate social and emotional behavior; impaired non-verbal communication; and uncoordinated motor skills. AS is likely caused by a combination of genetic and environmental influences. While autism spectrum disorders including AS sometimes run in families, no specific inheritance pattern has been recognized. | What is (are) Asperger syndrome ? |

Autism spectrum disorders including Asperger syndrome sometimes run in families, but no specific inheritance pattern has been recognized. The condition is likely caused by a combination of genetic and environmental factors, which means that not all people with a genetic predisposition will be affected. A consultation with a genetics professional is recommended for those with specific questions about genetic risks to themselves or family members. | Is Asperger syndrome inherited ? |

Ehlers-Danlos syndrome (EDS) is a group of inherited connective tissue disorders that is caused by abnormalities in the structure, production, and/or processing of collagen. There are 6 major forms of EDS: hypermobility type, classic type, vascular type, kyphoscoliosis type, arthrochalasia type, and dermatosparaxis type. Although other forms of the condition exist, they are extremely rare and are not well-characterized. The signs and symptoms of EDS vary by type and range from mildly loose joints to life-threatening complications. Features shared by many types include joint hypermobility and soft, velvety skin that is highly elastic (stretchy) and bruises easily. Changes (mutations) in a variety of genes may lead to EDS; however, the underlying genetic cause in some families is unknown. Depending on the subtype, EDS may be inherited in an autosomal dominant or an autosomal recessive manner. There is no specific cure for EDS. The treatment and management is focused on preventing serious complications and relieving associated signs and symptoms. | What is (are) Ehlers-Danlos syndrome ? |

There are six major types of Ehlers-Danlos syndrome (EDS). Although there is significant overlap in associated features, the subtypes are classified based on their unique signs and symptoms: Hypermobility type - characterized primarily by joint hypermobility affecting both large (elbows, knees) and small (fingers, toes) joints which may lead to recurrent joint dislocations and subluxations (partial dislocation). Affected people generally experience skin involvement (soft, smooth and velvety skin with easy bruising) and chronic pain of the muscles and/or bones, as well. Classic type - associated with extremely elastic (stretchy), smooth skin that is fragile and bruises easily; wide, atrophic scars (flat or depressed scars); and joint hypermobility. Molluscoid pseudotumors (calcified hematomas over pressure points such as the elbow) and spheroids (fat-containing cysts on forearms and shins) are frequently diagnosed in affected people. Hypotonia and delayed motor development may occur, as well. Vascular type - characterized by thin, translucent skin that is extremely fragile and bruises easily. Arteries and certain organs such as the intestines and uterus are also fragile and prone to rupture. Affected people typically have short stature; thin scalp hair; and characteristic facial features including large eyes, a thin nose and lobeless ears. Joint hypermobility is present, but generally confined to the small joints (fingers, toes). Other common features include club foot; tendon and/or muscle rupture; acrogeria (premature aging of the skin of the hands and feet); early onset varicose veins; pneumothorax (collapse of a lung); gingival (gums) recession; and a decreased amount of subcutaneous (under the skin) fat. Kyphoscoliosis type - associated with severe hypotonia at birth, delayed motor development, progressive scoliosis (present from birth), and scleral fragility. Affected people may also have easy bruising; fragile arteries that are prone to rupture; unusually small cornia; and osteopenia (low bone density). Other common features include a marfanoid habitus which is characterized by long, slender fingers (arachnodactyly); unusually long limbs; and a sunken chest (pectus excavatum) or protruding chest (pectus carinatum). Arthrochalasia type - characterized by severe joint hypermobility and congenital hip dislocation. Other common features include fragile, elastic skin with easy bruising; hypotonia; kyphoscoliosis (kyphosis and scoliosis); and mild osteopenia. Dermatosparaxis type - associated with extremely fragile skin leading to severe bruising and scarring; saggy, redundant skin, especially on the face; and hernias. For more information on each subtype, please click on the links above. You can also find more detailed information on Medscape References Web site or the Ehlers-Danlos National Foundations Web site. Although other forms of the condition exist, they are extremely rare and are not well-characterized. | What are the symptoms of Ehlers-Danlos syndrome ? |

Ehlers-Danlos syndrome can be caused by changes (mutations) in several different genes (COL5A1, COL5A2, COL1A1, COL3A1, TNXB, PLOD1, COL1A2, and ADAMTS2). However, the underlying genetic cause is unknown in some families. Mutations in these genes usually alter the structure, production, and/or processing of collagen or proteins that interact with collagen. Collagen provides structure and strength to connective tissues throughout the body. A defect in collagen can weaken connective tissues in the skin, bones, blood vessels, and organs resulting in the features of the disorder. | What causes Ehlers-Danlos syndrome ? |
|
The inheritance pattern of Ehlers-Danlos syndrome (EDS) varies by subtype. The arthrochalasia, classic, hypermobility, and vascular forms of the disorder usually have an autosomal dominant pattern of inheritance. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with one of these subtypes has a 50% chance with each pregnancy of passing along the altered gene to his or her child. The dermatosparaxis and kyphoscoliosis types of EDS are inherited in an autosomal recessive pattern. This means that to be affected, a person must have a mutation in both copies of the responsible gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier. | Is Ehlers-Danlos syndrome inherited ? |
|
A diagnosis of Ehlers-Danlos syndrome is typically based on the presence of characteristic signs and symptoms. Depending on the subtype suspected, some of the following tests may be ordered to support the diagnosis: Collagen typing performed on a skin biopsy may aid in the diagnosis of vascular type, arthrochalasia type, and dermatosparaxis type. Collagen is a tough, fiber-like protein that makes up about a third of body protein. It is part of the structure of tendons, bones, and connective tissues. People with Ehlers-Danlos syndrome often have abnormalities of certain types of collagen. Genetic testing is available for many subtypes of Ehlers-Danlos syndrome; however, it is not an option for most families with the hypermobility type. Imaging studies such as CT scan, MRI, ultrasound, and angiography may be useful in identifying certain features of the condition. Urine tests to detect deficiencies in certain enzymes that are important for collagen formation may be helpful in diagnosing kyphoscoliosis type. | How to diagnose Ehlers-Danlos syndrome ? |

There is no specific cure for Ehlers-Danlos syndrome (EDS). The treatment and management is focused on preventing serious complications and relieving associated signs and symptoms.
