The NUP98-PSIP1 gene fusion is caused by a rare but recurrent chromosomal translocation t(9;11)(p22;p15) reported in adult and pediatric acute myeloid leukemia (AML), chronic myeloid leukemia (CML), and myelodysplastic syndrome [121,122,123,124,125,126,127,128]. Here, NUP98 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
