Mutated <i>WT1</i>, <i>FLT3-ITD,</i> and <i>NUP98-NSD1</i> Fusion in Various Combinations Define a Poor Prognostic Group in Pediatric Acute Myeloid Leukemia.
High PRDM16 (also known as MEL1) expression is a representative marker of acute myeloid leukemia (AML) with NUP98-NSD1 and is a significant predictive marker for poor prognosis in pediatric AML.
The analysis of the clonal structure in these cases suggests that the mutation order in the NUP98-rearranged pediatric AML begins with the NUP98 rearrangement leading to epigenetic dysregulations then followed by mutations of critical hematopoietic transcription factors and finally, activation of the FLT3 signaling pathway.
We report a novel fusion of the NUP98 and LEDGF genes in a pediatric AML with intermediate characteristics between M2-M3 French-American-British (FAB) subtypes exhibiting the same chromosomal rearrangement.
