[Research on NPM1 gene mutations in acute myeloid leukemia].

Nucleolar phosphoprotein (nucleophosmin 1, NPM1), also known as B23, N038, is located in the nucleolar particles of a multifunctional protein widely expressed in various types of cells. At present, a number of studies found that the NPM1 gene mutation is the most frequent acquired molecular genetic abnormalities in acute myeloid leukemia (AML), especially in normal karyotype AML (nk-AML). NPM1 mutation is a special subgroup in AML, which has relatively unique clinical features, and is the independent prognostic indicators of AML. Research on NPM1 mutation has an important clinical significance in the diagnosis, treatment and prognosis judgment of AML patients. This article reviews the discovery of NPM1 gene mutation in AML in recent years, including structure and physiological functions of NPM1 gene, NPM1 gene mutation in AML, detection methods of NPM1 gene mutation, and so on.
