NPM1

NPM1 (nucleophosmin) exon 12 insertions create cytoplasmic NPM1c in ~30% AML; NPM1c sequesters ARF → reduced p53 activity; NPM1c AML is a WHO-defined entity with favorable prognosis if FLT3-ITD negative; NPM1 mRNA is a sensitive MRD marker by RT-qPCR.

Also known as: NPM1, nucleophosmin, NPM1c, NPM1 AML, NPM1 mutation, NPM1c cytoplasmic, B23 nucleophosmin, NPM1-ALK
