Predisposición genética común en la depresión mayor y el trastorno de estrés postraumático en hombres

MD-PTSD comorbidity is largely explained by common genetic influences. Substantial genetic overlap between MD and PTSD implies that genes implicated in the etiology of MD are strong candidates for PTSD and vice versa. Environmental influences on MD and PTSD explain less of their covariation and appear to be largely disorder-specific. Research is needed to identify environmental factors that influence the development of MD versus PTSD in the context of common genetic liability.
