Association of XRCC1 Arg399Gln and Arg194Trp polymorphisms with susceptibility to multiple autoimmune diseases: a meta-analysis.
The role of the X-ray repair cross-complementing gene 1(XRCC1) Arg399Gln and Arg194Trp polymorphisms has been involved in the investigations of susceptibility to multiple autoimmune diseases, but the results were inconsistent. Here, we have performed a meta-analysis to clarify the relationship between them. All appropriate case-control studies were searched in the PubMed, EMBASE and Chinese National Knowledge Infrastructure (CNKI) database. A meta-analysis was conducted on the association between the XRCC1 two polymorphisms (Arg399Gln, Arg194Trp) and risk of autoimmune diseases. Pooled odds ratios (OR) with 95% confidence intervals (CI) were conducted to assess the association. Fourteen relevant studies with a total of 2886 cases and 3257 controls were analyzed in our research. Analysis for the XRCC1 Arg399Gln polymorphism under recessive model (OR 1.53, 95% CI 1.07-2.18, P = 0.019), dominant model (OR 1.36, 95% CI 1.04-1.77, P = 0.026) and homozygous model (OR 1.67, 95% CI 1.07-2.62, P = 0.024) indicated an association in the overall population, as well as in Caucasian populations under the recessive model (OR 1.73, 95% CI 1.03-2.91, P = 0.039) and Asian populations under dominant model (OR 1.31, 95% CI 1.02-1.70, P = 0.037). Stratification by disease indicated significant association between XRCC1 Arg399Gln and rheumatoid arthritis (RA) in all genetic models (P < 0.05). However, there was no significant association between XRCC1 Arg194Trp polymorphism and autoimmune diseases in different genetic models. The current meta-analysis demonstrates that the XRCC1 Arg399Gln polymorphism confers susceptibility to autoimmune diseases in Asians and Caucasians and, in particular, shows that XRCC1 Arg399Gln polymorphism is associated with RA.
