【摘要】:精神分裂症是一种异质性精神障碍,目前多数学者认为该病由遗传及环境风险因子共同致病.传统的遗传学研究识别了一些精神分裂症的候选基因,然而,外显率及比值比较低,以及可重复性较差,使得这些候选基因在精神分裂症发病机制中的角色受到限制.精神分裂症的流行病学研究发现了一些可能与该病相关的环境风险因子,但仍受到方法学的限制以及互相矛盾的流行病学调查结果的困扰.目前,在环境与基因中间起调解作用的表观遗传学,可能在精神分裂症的发病机制中起重要作用.DNA甲基化是最稳定且研究最深入的一种表观遗传学修饰.本文简要介绍DNA甲基化机制,主要评述精神分裂症中基因组及特异位点如候选基因Reelin与COMT甲基化研究现状,以及DNA甲基化在精神分裂症中的研究困境.
