智能发育迟缓与几百种遗传性综合征有关,在Rett综合征,脆性X综合征等多种智能发育迟缓的患者中发现了MECP2基因突变,MECP2基因已成为研究基因型与人类神经发育性疾病的关系的一个热点方向,现将其研究现状作一综述。
Mental retardation is associated with several hundred hereditary syndromes and mutations in the MECP2 gene have been found in a variety of retarded developmental disorders such as Rett syndrome and Fragile X syndrome. The MECP2 gene has been used to study genotypic and neurodevelopmental disorders The direction of a hot spot, now its research status to be reviewed.
