Stress-Related Negative Affectivity and Genetically Altered Serotonin Transporter Function

Abstract

Genotype x environment interactions in depression may be more productively interpreted by involving mechanisms more proximal to psychological experience itself. The probability that stress-related cognitive vulnerabilities for depression result in symptom formation may be moderated by a neurobiologic phenotype characterized by altered processing of negative emotions associated with variation in 5-HTTLPR.
