Japanese Cohort Study Identifies an Association Between the Serotonin Transporter–Linked Polymorphic Region and Suicide Death

Key Points

This study investigates the relationship between 5-HTTLPR polymorphisms and the risk of suicide death.
Cohort study design
Focus on Japanese population
Genetic analysis of 5-HTTLPR polymorphisms
Identified potential association between 5-HTTLPR polymorphisms and suicide death
Findings suggest a genetic component to suicide risk in the studied population

Abstract

Our findings indicate a potential association between 5-HTTLPR polymorphisms and suicide death in a Japanese population. Although further research in larger and diverse samples is warranted, these results may contribute to a better understanding of the biological underpinnings of suicide risk.
