COMT基因与精神分裂症患者暴力攻击行为关联性的研究进展

Progress on Association between COMT Gene and Violence Behavior in Patients with Schizophrenia

精神分裂症患者的暴力攻击行为发生率高于一般人群,暴力攻击行为在某些方面具有显著的遗传倾向性,与精神分裂症患者暴力攻击行为研究最多的是儿茶酚氧位甲基转移酶(catechol-O-methyltransferase,COMT)基因。本文从COMT Val158Met和COMT Ala72Ser的SNP多态性、COMT基因单倍型、COMT基因启动子区DNA甲基化等方面对COMT基因变异与精神分裂症患者暴力攻击行为的相关性研究进行综述,并提出精神分裂症患者暴力攻击行为的遗传学研究方向。

The prevalence of violence behavior in patients with schizophrenia is higher than that in common population. Data suggest that genetic factors may play a substantial role for the etiology of the behavior. Among the particular gene polymorphisms that have been considered to be involved in violence behavior, the catechol-O-methyltransferase （COMT） gene had been the focus of recent research. This article reviews the association research between COMT gene and violence behavior in patients with schizophrenia in several aspects： SNP polymorphism of COMT Val158Met and COMT Ala72Ser, haplotype of COMT gene and DNA methylation of promoter region of COMT gene. The genetic research direction is presented for patients with schizophrenia.
