Leuk Res. 2005 Apr;29(4):467-70. doi: 10.1016/j.leukres.2004.09.002. Epub 2004 Dec 9.

Abstract

The rare t(9;11)(p22;p15) translocation is associated with adult acute myeloid leukemia (AML) with immature forms. We report a novel fusion of the NUP98 and LEDGF genes in a pediatric AML with intermediate characteristics between M2-M3 French-American-British (FAB) subtypes exhibiting the same chromosomal rearrangement. Fluorescence in situ hybridization (FISH) and reverse transcriptase-PCR (RT-PCR) studies identified the chimeric transcript product of in-frame fusion of NUP98 exon 8 to LEDGF exon 4.
