Table Less common cytogenetic abnormalities include the following: t (v; 11q23) / MLL or KMT2A rearranged, including t (4; 11) / KMT2A-AF4 t (1; 19) / E2A-PBX1 (TCF3-PBX1) t (5; 14) / IL3-IGH t (8; 14), t (8; 22), t (2; 8) / C-MYC rearranged BCR-ABL - like acute lymphoblastic leukemia overlaps genetically with ALL in which the Philadelphia chromosome [a reciprocal balanced translocation between chromosomes 9 and 22, t (9; 22)] is present (Ph+ ALL).
