Variant translocations (9;11): identification of the critical genetic rearrangement.
The t(9;11)(p22;q23) is a recurring abnormality in acute nonlymphocytic leukemia. The analysis of complex 9;11 translocations will aid in the identification of the conserved chromosomal junction or the critical genetic alteration created by the rearrangement; however, variant translocations involving chromosomes #9 and #11 have not been reported. We have identified such variants in two patients who had acute myelomonocytic leukemia and acute monocytic leukemia, characterized by a t(9;11;18)(p22;q23;q12) and a t(9;11;13)(p22;q23;q34), respectively. The conserved junction resulting from these rearrangements is created by the translocation of chromosomal material from 9p to 11q.
