Abstract

Posttraumatic Stress Disorder (PTSD) is a debilitating condition arising after exposure to traumatic events, characterized by symptoms such as intrusive memories, hyper arousal, and avoidance. Despite its significant impact on mental health, the genetic underpinnings of PTSD remain partially understood. This article reviews recent advancements in the genomic study of PTSD, focusing on the contributions of the Psychiatric Genomic Consortium (PGC). We discuss key findings from genomic studies, the role of genetic variation in PTSD susceptibility, and future directions for research. Through an analysis of the PGC's contributions, this review aims to highlight the potential for genomic approaches to enhance understanding and treatment of PTSD.
