Abstract

Chromosome translocations leading to gene fusions have emerged as important oncogenic drivers of various types of malignancies. Detection and characterization of these fusion genes not only help diagnosis and management of specific malignancies, but also contribute to our understanding of the genetic basis and pathogenesis of these diseases. NUP98 gene encodes a 98 kDa nucleoporin, which is a component of the nuclear pore complex that mediates transport of mRNA and proteins between the nucleus and the cytoplasm. Due to its participation in translocations leading to the formation of fusion with at least 29 different partner genes, NUP98 is considered one of the most promiscuous fusion genes in hematologic malignancies. We discuss our identification and characterization of a NUP98-PHF23 fusion from a cryptic translocation in patients with acute myeloid leukemia (AML).
