First case report of a NUP98-PMX1 rearrangement in de novo acute myeloid leukemia and literature review.

ABSTRACT:

Background

The nucleoporin 98 (NUP98)-paired related homeobox 1 (PMX1) fusion gene, which results from t(1;11)(q23;p15), is rare in patients with acute myeloid leukemia (AML). Currently, only two cases of chronic myeloid leukemia in the accelerated phase or blast crisis and three cases of therapy-related AML have been reported. Here, we first report a patient with de novo AML carrying the NUP98-PMX1 fusion gene.

Case presentation

A 49-year-old man diagnosed with AML presented the karyotype 46,XY,t(1;11)(q23;p15)[20] in bone marrow (BM) cells. Fluorescence in situ hybridization analysis using dual-color break-apart probes showed the typical signal pattern. Reverse transcription-polymerase chain reaction (RT-PCR) analysis suggested the presence of the NUP98-PMX1 fusion transcr
