Trisomy 11 in myeloid malignancies is associated with internal tandem duplication of both MLL and FLT3 genes

Haematologica. 2005 Feb;90(2):262-4.

Abstract

In 20 patients with myeloid malignancies and isolated trisomy 11 an internal tandem duplication of the MLL and FLT3 genes was observed in 41% and 31% of the cases, respectively; 80% of the FLT3+ cases showed MLL self-fusion. Concomitant presence of MLL and FLT3 anomalies could be relevant in determining the poor outcome of patients with acute myeloid leukemia with trisomy 11.
