SSTR4, childhood adversity, self-efficacy and suicide risk in alcoholics

Abstract

Patients with alcohol dependence (AD) are known to develop poor social skills, to report a higher number of adverse childhood experiences (ACEs) and to attempt suicide more frequently than the general population. The background for the association between ACEs and a higher risk of suicide still remains understudied. SSTR4 rs2567608 is a functional polymorphism of the gene for somatostatin receptor subtype 4, predominantly found in the CA1 hippocampus area and involved in memory formation. We hypothesize that the functional polymorphism SSTR4 rs2567608, general self-efficacy, and adverse childhood experiences influence the risk of suicide attempt in patients with AD.
