In 1 of 51 cases of acute myeloid leukemia (601626) with positivity for NPM in the cytoplasm, Falini et al. (2005) identified a 4-bp insertion in exon 12 of the NPM1 gene (960insCCTG), resulting in a shift in the reading frame that was predicted to alter the C-terminal portion of the protein by replacing the last 7 amino acids with 11 different residues. Falini et al. (2005) called this mutation D.
