本文就基因-环境相互作用(GxE)在创伤后应激障碍(PTSD)病因学中的研究进展作一综述。我们开始的讨论,为什么创伤后应激障碍是唯一适合的创新框架的GXE方法,其次是审查的遗传性和主要影响分子遗传学研究的创伤后应激障碍。接下来,我们讨论迄今为止关于PTSD的六项GxE调查。最后,我们讨论了未来的方向和意义,这项研究,强调心理社会因素的扩展,可能是拟合“E”变量列入这一新的研究领域。我们认为,GxE研究对于阐明暴露于潜在创伤事件后的风险和恢复力至关重要。
This article provides a detailed review of the extant gene-environment interaction (GxE) research in the etiology of posttraumatic stress disorder (PTSD). We begin by a discussion of why PTSD is uniquely fitting for the innovative framework of GxE methodology, followed by a review of the heritability and main effect molecular genetics studies of PTSD. Next, we discuss the six GxE investigations to date on PTSD. We end with a discussion of future directions and significance of this research, with an emphasis on the expansion of psychosocial factors that may be fitting ‘E’ variables for inclusion in this new research area. We posit that GxE research is vital to elucidating risk and resilience following exposure to a potentially traumatic event.
