Abstract
Chromosomal rearrangements of the lysine methyltransferase 2A (KMT2A or MLL) gene are observed in ;10% of all acute leukemias, with particularly high frequency (;80%) in infant acute lymphoblastic leukemia (ALL),1 where, despite aggressive chemotherapy, patients still experience poor outcome and long-term side effects.2 Mixed lineage leukemia (MLL) rearrangements (MLL-r) also indicate particularly poor outcomes for patients with acute myeloid leukemia (AML).3 Mechanistically, MLL-r frequently generates fusion proteins involving partners that function in the super elongation complex,4 the result of which is aberrant recruitment to MLL target genes of the positive transcription elongation fact..
