The association between the COMT rs4680 (G>A, Val-158-Met) polymorphism and the risk of fibromyalgia has been investigated in previous studies, but the results are controversial. Therefore, a meta-analysis has been performed to confirm the association between COMT rs4680 (G>A, Val-158-Met) polymorphism and the risk of fibromyalgia in this study. Our study includes eleven case-control studies with 2,909 individuals comprised of 1,365 fibromyalgia patients and 1,544 control subjects. The regression analysis was performed using the random effects model or the fixed effects model and OR with the corresponding 95 % CI was calculated for the allele, recessive, dominant, over-dominant, co-dominant 1, and co-dominant 2 model. No statistical significant associations were observed between COMT rs4680 (G>A, Val-158-Met) polymorphism and risk of fibromyalgia in allele model (P-value = 1.00), recessive model (P-value = 1.00), dominant model (P-value = 0.54), co-dominant 1 model (P-value = 1.00) and co-dominant 2 model (P-value = 1.00). In conclusion, our meta-analysis showed that the COMT rs4680(G>A, Val-158-Met) polymorphism might not be genetic risk factor for the fibromyalgia. KCI Citation Count: 0
