The SET-NUP214 fusion gene has been rarely reported in acute myeloid leukemia, acute undifferentiated leukemia, and recurrently in T-cell acute lymphoblastic leukemia.     ///    Molecular characterization of alternative SET-NUP214 fusion transcripts in a case of acute undifferentiated leukemia..     ///    "Herein we present a novel case of acute undifferentiated leukemia with SET-NUP214 rearrangement due to the cryptic deletion of the 9q34 region producing two different types of fusion transcripts by alternative splicing and molecular characterization of the fusion transcripts by fluorescence in situ hybridization, reverse transcriptase-polymerase chain reaction, and array comparative genomic hybridization analyses..
