Inversion (11)(p15q22) with NUP98–DDX10 fusion gene in pediatric acute myeloid leukemia

The inv(11)(p15q22), a rare but recurrent chromosome abnormality that creates a NUP98–DDX10 fusion gene, is associated with de novo or secondary myeloid malignancies. We report a case of acute monocytic leukemia presenting this rearrangement, studied using fluorescence in situ hybridization (FISH) and reverse transcriptase-PCR (RT-PCR). We also review the cases of inv(11) associated with NUP98–DDX10 reported in the literature.
