摘　　要：孤独症谱系障碍(ASD)是神经发育过程中的一种发育障碍性疾病,是多个易感基因参与发病的多基因疾病。目前已报道的易感基因有100多个,相关研究包括易感基因的染色体位点研究、易感基因筛查研究和易感基因的表观遗传学异常。已报道的易感基因编码的蛋白质有:神经细胞粘着分子;离子通道蛋白;支架蛋白;蛋白激酶、受体、载体;信号通路调控蛋白以及昼夜节律相关蛋白。易感基因突变和表达调控机制的研究进展有助了解ASD的遗传参与的发病机制,可望能给ASD的诊断和治疗提供新的思路。该文对ASD易感基因方面的研究现状进行了综述。Autism spectrum disorder（ASD） is a kind of neurodevelopmental multigenic disorder. More than one hundred of candidate genes for ASD have been reported. The candidate gene research for ASD involves in chromosome loci and screening of candidate genes and epigenetic abnormalities for candidate genes. The reported genes encode neural adhesion molecules, ion channels, scaffold proteins, protein kinases, receptor protein and carrier protein, signaling modulate molecules and circadian relevant proteins. The research of mutation screening and expression regulation of candidate genes can help to elucidate genetic mechanisms for ASD, and may provide new approaches for the diagnosis and treatment of this disorder. This article reviews the research advance in candidate genes for ASD.
