Translocation (6;9)(p23;q34) in acute nonlymphocytic leukemia

A consistent chromosomal abnormality t(6;9)(p23;q34) was demonstrated in the bone marrow or unstimulated peripheral blood cultures of two patients with acute nonlymphocytic leukemia (ANLL). Only two additional cases with ANLL and a similar cytogenetic finding have been reported, indicating that this translocation may represent another chromosomal abnormality specifically associated with ANLL.
