Abstract

In hematologic malignancies chromosome aberrations generating fusion genes include cryptic deletions. In a patient with acute myeloid leukemia and normal karyo-type we discovered a new cryptic 9q34 deletion and here report the cytogenetic and molecular findings. The 9q34 deletion extends 2.5 megabases and juxtaposes the 5' TAF-I to the 3' CAN producing a TAF-I/CAN fusion gene. TAF-I/CAN transcribes into two fusion proteins bearing either TAF-Ialpha or TAF-Ibeta moieties. We set up molecular assays to monitor the chimeric TAF-Ialpha/CAN and TAF-Ibeta/CAN transcripts which, after hematopoietic stem cell transplantation from an HLA-identical sibling, were no longer detected.
