Abstract

Many mental disorders represent the extremes of the normal distribution of traits, which are related to multiple cognitive and emotional dimensions. By performing whole-exome sequencing of healthy, young subjects with extremely high versus extremely low aversive memory performance, we identified TROVE2 as a gene implicated in emotional memory in health and disease. TROVE2 encodes Ro60, a broadly expressed RNA-binding protein implicated in the regulation of inflammatory gene expression and autoimmunity. A regulatory TROVE2 variant was linked to higher emotional memory capacity and higher emotional memory-related brain activation in healthy subjects. In addition, TROVE2 was associated with traumatic memory and the frequency of post-traumatic stress disorder in genocide survivors.
