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.
核仁磷蛋白(核仁素1,NPM1),也被称为B23、N038,是一种位于核仁颗粒中的多功能蛋白,广泛表达于各种类型的细胞中。目前,多项研究发现,NPM1基因突变是急性髓系白血病(AML)中最常见的获得性分子遗传异常,尤其是在正常核型AML(nk-AML)中。NPM1突变是AML中的一个特殊亚组,具有相对独特的临床特征,是AML的独立预后指标。对NPM1突变的研究在AML患者的诊断、治疗及预后判断中具有重要的临床意义。本文综述了近年来AML中NPM1基因突变的发现,包括NPM1基因的结构和生理功能、AML中的NPM1基因突变、NPM1基因突变的检测方法等。
