Furthermore, six of the 14 TEL/AML1-selected genes (TNFRSF7, CD9, TCFL5, PIK3C3, CBFA2T3, SEMA6A) had previously been reported to be associated with TEL/AML1 signatures found in more heterogeneous groups of ALL patients (including those with T-ALL, Bcr-Abl, E2A-PBX, or MLL) [13,15]. The gene discussed is KMT2A; the disease is acute lymphoblastic leukemia.
