Abstract: Objective To investigate the relationship between the peptidyl arginine deiminase 4 (PADI4) gene single nucleotide polymorphisms and the risk of rheumatoid arthritis(RA).  Methods Meta-analysis was performed to estimate the pooled odd ratio to assess the risk of RA associated with PADI4 gene polymorphisms. The heterogeneity test,bias evaluation and risk ratio on Meta-analysis were performed.  Results A total of 13 literature studies with 11 039 cases and 10 395 controls were included for Meta-analysis based on criteria. According to heterogeneity test,Asian and European groups were analyzed respectively for PADI4-94 using fixed effect model,and the same model was used to PADI4-104 with one study having heterogeneity. The results of Meta-analysis showed PADI4-94 single nucleotide polymorphisms were associated with the risk of RA for Asian people,but not with that for European people,and PADI4-104 single nucleotide polymorphisms had the high risk of RA for all. Bias analysis confirmed the conclusion by trim and fill method.  Conclusions PADI4-94 and PADI4-104 single nucleotide polymorphisms are associated with the risk of RA.
