MYB and T-cell acute lymphoblastic leukemia: Recurrent genomic alterations affecting MYB function have been identified in T-cell acute lymphoblastic leukemia and include amplifications or translocations of the MYB gene [3, 4] or result in the generation of de novo MYB-binding sites upstream of the TAL1 or LMO2 genes to stimulate their expression [5, 6].
