脆性X综合征是家族性智力低下的常见病因之一,遗传学研究表明染色体的Xq27.3脆性位点与其相关。自1991年在此位点附近发现FMR-1基因以来,许多学者对此进行了大量研究,获得一些重要相关资料,本文在此简要作一综述。
Fragile X syndrome is one of the common causes of familial mental retardation. Genetic studies show that Xq27.3 fragile loci of chromosomes are related to it. Since the discovery of the FMR-1 gene near this locus in 1991, many scholars have done a lot of research and obtained some important related information. This article is briefly reviewed here.
