Abstract
The current study aimed to investigate the interaction between the serotonin 1A receptor gene (HTR1A) C-1019G polymorphism and recent negative life stressors on depression in a Korean community sample. The HTR1A C-1019G polymorphism was genotyped in 416 community-dwelling Koreans (156 males, 260 females; 44.37 ± 14.67 years old). Lifetime and current major depressive episodes were diagnosed using the Structured Clinical Interview for DSM-IV. The Center for Epidemiological Studies for Depression Scale (CES-D) was self-applied and face-to-face interviews investigating negative life stressors within the last 6 months were also performed. The results indicated that there were significant interactions between the C-1019G polymorphism and negative life stressors on CES-D scores (p = 0.02) as well as on current major depressive episodes (p = 0.002), but not on past major depressive episodes. G carriers alone had higher CES-D scores and more frequently experienced major depressive episodes after stressors. The interaction between the C-1019G polymorphism in HTR1A and recent negative life stressors accounted for current major depressive episodes and depressive symptoms. Our findings suggest that people with this gene variant may be more susceptible to developing depression especially after negative life stressors. © 2011 S. Karger AG, Basel.
