This meta-analysis investigated the relationship between TGF-beta 1 gene polymorphisms and systemic lupus erythematosus (SLE), and found that TGF-beta 1 C509T, G915C, and T869C polymorphisms were not associated with SLE risk.
Background: The relationship between transforming growth factor-beta 1 (TGF- beta 1) gene polymorphisms and systemic lupus erythematosus (SLE) has been reported in many studies, but there were still controversies with regard to their conclusions.Methods: Relevant documents were retrieved from 5 electronic databases such as PubMed, Embase, Cochrane Library, Wanfang, and China national knowledge infrastructure. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were used to assess the relationship between TGF-beta 1 genetic variation and SLE.Results: The present meta-analysis included 12 case-control studies with 1308 SLE patients and 1714 healthy controls. The results of the combined analyses showed that TGF-beta 1 C509T polymorphism showed no association with SLE risk (TC vs CC: OR = 1.16, 95% CI = 0.91-1.48, P (Heterogeneity) (P-H) = 0.579; TT vs CC: OR = 1.15, 95% CI = 0.63-2.09, P-H = 0.003; T vs C: OR = 1.08, 95% CI = 0.8-1.45, P-H = 0.003; TC/TT vs CC: OR = 1.17, 95% CI = 0.93-1.46, P-H = 0.133; and TT vs TC/CC: OR = 1.06, 95% CI = 0.64-1.76, P-H = 0.004). TGF-beta 1 G915C and T869C polymorphisms were not linked with SLE risk. Moreover, subgroup analysis stratified by ethnicity and Hardy-Weinberg equilibrium revealed no significant correlation of TGF-beta 1 T869C, C509T, G915C polymorphisms with SLE risk.Conclusion: TGF-beta 1 T869C, C509T, G915C polymorphisms might not be associated with the development of SLE.
