Abstract

OBJECTIVE: To evaluate the association between the transforming growth factor β1 gene-509C/T (TGF-β1-509C/T) polymorphism and the risk of endometriosis. STUDY DESIGN: Relevant studies published before October 2011 were identified by searching PubMed and Embase. Studies were selected using prior defined criteria. The strength of the relationship between the TGF-β1-509C/T polymorphism and endometriosis risk was assessed by Odds Ratios (ORs). Fixed- or random-effects model was calculated according to study heterogeneity. Stratification analysis and sensitivity analysis were also conducted. Possible publication bias was tested by funnel plots and Egger's test. RESULTS: Of 49 potentially relevant studies, six case-control studies were identified in this meta-analysis. The integrated result showed that the TGF-β1-509C/T polymorphism was not associated with the endometriosis risk for the allele contrast (T vs. C: OR=1.57, 95%CI=0.88-2.79), the additive genetic model (T/T vs. C/C: OR=2.96, 95%CI=0.97-9.10), the dominant genetic model (T/T+T/C vs. C/C: OR=1.80, 95%CI=0.80-4.07) and the recessive genetic model (T/T vs. C/C+T/C: OR=1.91, 95%CI=0.89-4.12). In the stratified analysis by ethnicity, genotyping method and source of control, no significantly association was found. Publication bias was not detected in the included studies. CONCLUSIONS: Meta-analyses of the available data showed that the association between TGF-β1-509C/T polymorphism and susceptibility of endometriosis was not significant. More studies are needed to elucidate its role in endometriosis.
