The Val158Met polymorphism of the COMT gene has been implicated in susceptibility to uterine leiomyoma (ULM), but the reported results were inconclusive. The aim of the study was to evaluate the Val158Met polymorphism of the COMT gene and the risk of ULM by meta-analysis. A comprehensive electronic search for relevant articles was conducted in Pubmed, Embase, CNKI, Wanfang, and Weipu databases. Statistical analysis was performed by using the Revman4.2 software and Stata10.0 software. A total of 7 articles including 12 case-control studies were identified in this meta-analysis. The results showed that the polymorphism was associated with decreased risk of ULM (Met/Met. +. Val/Met vs. Met/Met: OR=0.84, 95% CI=0.70-0.99, Z=2.07, p=0.04). In the subgroup analyses by ethnicity, significant decreased risk was found among the black populations (OR=0.68, 95% CI=0.48-0.97, Z=2.15, p=0.03). The current meta-analysis suggested that the Val158Met polymorphism in the COMT gene was associated with decreased risk of ULM, especially in the black population. Future studies are needed to validate our conclusions. © 2013 Elsevier B.V. Source
