In another study of 5 MLL-rearranged infant ALL samples, genes known to be involved in oncogenesis and tumor progression (DAPK1, CCR6, HRK, LIFR, and FHIT) were differentially methylated suggesting a role in the leukemogenesis of MLL-rearranged ALL (17). The gene discussed is KMT2A; the disease is acute lymphoblastic leukemia.
