A new subtype of MLL-SEPT2 fusion transcript in therapy-related acute myeloid leukemia with t(2;11)(q37;q23): a case report and literature review

The t(2;11)(q37;q23) is a rare recurrent cytogenetic abnormality associated with de novo and therapy-related acute myeloid leukemia, resulting in a MLL-SEPT2 fusion gene. We report on a case of therapy-related acute myeloid leukemia M2 showing a t(2;11)(q37;q23) and resulting in a new subtype of a MLL-SEPT2 chimeric transcript. The literature on this translocation is reviewed.
