Nucleophosmin (NPM1, also known as nuclear phosphoprotein B23, numatrin) is a gene that encodes a phosphoprotein, which is involved in the regulation of the interactions of ARF and p53. Fusions, missense mutations, nonsense mutations, frameshift insertions and deletions, and in-frame deletions and insertions are observed in cancers such as acute myeloid leukemia and skin cancer.

NPM1 is altered in 0.86% of all cancers with leukemia, non-small cell lung carcinoma, colorectal adenocarcinoma, breast carcinoma, and melanoma having the greatest prevalence of alterations [3].

NPM1 GENIE Cases - Top Diseases

The most common alterations in NPM1 are NPM1 Mutation (1.00%), NPM1 W288Cfs*12 (0.61%), NPM1 Amplification (0.08%), NPM1 Loss (0.04%), and NPM1 L287Ffs*13 (0.03%) [3].
