Abstract: Several association studies have indicated that the HTR1A gene is associated with suicidal behavior (SB). Thus, a systematic assessment of the association of HTR1A was performed based on a literature review and pooled analysis. Four electronic databases were comprehensively searched to find and pinpoint all case–control articles related to this study. When analyzing the genetic association with SB, data were divided into: (A) SB cases vs. healthy controls and (B) SB cases vs. psychiatric controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were assessed as measures of association. Heterogeneity among included studies was analyzed using sensitivity test and Q statistics. Publication bias was also explored by Egger and rank correlation test. Thirteen case–control studies were selected in this meta-analysis, involving 2817 SB patients, 2563 healthy controls and 545 psychiatric controls. In the overall comparison between SB cases and healthy controls, result showed that the rs6295 polymorphisms of HTR1A gene was associated with SB, but only when using the recessive model (OR = 2.21, 95% CI = 1.80–2.71, P < 0.001). In the smaller sample size comparison between SB and psychiatric controls, no significant association was detected with rs6295 in any of the five genetics models tested. The present meta-analysis suggests that rs6295 polymorphism of HTR1A gene could increase the risk for SB. Well-designed studies with more patients will be required to validate these results.
