No Interaction Between Childhood Maltreatment and Serotonin Transporter Gene in Recurrent Major Depressive Disorder: A Clinical Sample

Abstract

Introduction: There is inconsistent evidence of interaction between childhood adversities and a serotonin transporter promoter polymorphism (5- HTTLPR) in depression. It is hypothesized that genetic sensitivity to stress could be more specific to recurrent major depressive disorder (MDD). The aim of the study is to replicate a recent study which provided preliminary evidence of interaction between severity of childhood maltreatment and the 5-HTTLPR polymorphism in recurrent MDD.
