ABSTRACT
BACKGROUND:
Genetic factors were suggested to have influence on the development of post-traumatic stress disorder (PTSD). The possible association between catechol-O-methyltransferase (COMT) Val158Met polymorphism and PTSD has been evaluated in several studies. But the results were still controversial. Therefore, we conduct this meta-analysis to address these issues.METHODS:
The PubMed, EMBASE, Cochrane Library, and Web of Science databases were searched for eligible studies. The pooled odds ratio (OR) with 95% confidence interval (CI) was calculated to estimate the association between COMT Val158Met polymorphism and PTSD.RESULTS:
Five articles including 6 studies with 893 cases and 968 controls were finally included in the present meta-analysis. The pooled analyses did not demonstrate a significant association between the COMT Val158Met polymorphism and PTSD in any of the selected genetic models allele model (OR = 1.13, 95% CI 0.97-1.31), dominant model (OR = 1.17, 95% CI 0.93-1.46), recessive model (OR = 1.44, 95% CI 0.78-2.66), and additive model (OR = 1.54, 95% CI 0.85-2.80). Subgroup analyses suggested that the Hardy-Weinberg equilibrium status of genotype distributions could influence the relationship of COMT Val158Met polymorphism and PTSD.CONCLUSIONS:
The present meta-analysis suggested that the COMT Val158Met polymorphism may not be associated with the PTSD risk. Further large-scale and population-representative studies are warranted to evaluate the impact of the COMT Val158Met polymorphism on the risk of PTSD.Key words
