摘要
FL33属于Ⅲ型受体酪氨酸激酶家族成员之一,研究表明,其在正常造血及免疫系统的发育中起重要调节作用。FLT3基因突变常见有两种,即内串联复制和点突变。FLT3在急性髓细胞白血病中有过度表达,FLT3基因的内部串联重复(FLT3-ITD)是急性髓细胞白血病最常见的基因异常。FLT3还可作为白血病基因诊断及微小残留病灶的检测标志。本文就FLT3及其突变与白血病的发生、发展及预后的关系予以综述。
FLT3 is a member of receptor tyrosine kinases type Ⅲ family, which play an important regula- tory role in the normal hematogenesis and immune system, There are two common gene mutation of FLT3, which are called internal tandem duplication and point mutation. It has overexpression in acute myelogenous Leukemia(AML) ,FLT3-1TD is the most common gene mutation in AML. FLT3 expression can be used as a gene symbol in the diagnosis of leukemia and the detection of minimal residual disease. This article reviews the relativity of FLT3 mutation with the genesis, development and prognosis of different kinds of leukemia.
