sentence1: The overall accuracy of our gene expression classifier was ~88%, and all T-ALL, TEL-AML1-positive, hyperdiploid and E2A-rearranged cases were correctly classified (i.e., 100% sensitivity) which resembled the data previously reported using other strategies for probe set selection and classifier construction.
sentence2: A gene that warrants further studies is the erythropoietin receptor that is 7.4-fold higher expressed in TEL-AML1-positive cases compared to other precursor B-ALL cases confirming other gene expression classification studies.
