Duchenne肌营养不良基因突变与智力关系的研究进展

随着分子生物学技术水平的不断提高,近年来对Duchenne肌营养不良(DMD)基因突变类型与智力发育关系的研究不断深入.DMD患儿的智力水平与基因突变类型存在一定的联系,DMD基因突变发生在45号外显子后,尤其是63号外显子后的患者发生智力低下的程度大于发生在45号之前外显子的突变,提示DMD基因突变越接近3'端越有可能导致智力低下.

The development of relationship between DMD gene mutation and intelligence with Duchenne muscular dystrophy

With the development of the molecular biology technic in recent years, the research about the relations between the type of gene mutation and the intelligence growth with the Duchenne muscular dystrophy (DMD) was developed.There are some connections in the intelligence and the type of gene mutation of the children with DMD. The children with DMD have lower intelligence when the mutation is after the 45 exon especially the 63 exon than before the 45 exon. It has more possibility to cause the lower intelligence when the the DMD gene mutation is closer to the end of 3'terminal.
