OBJECTIVE: The association of STAT4 gene polymorphism with systemic lupus erythematosus (SLE) / lupus nephritis (LN) results from the published studies is still conflicting. This meta-analysis was performed to evaluate the relationship between STAT4 rs7574865, rs16833431, rs11889341, rs8179673, rs10168266, rs7582694, rs3821236, rs7601754 gene polymorphism and SLE / LN, and to explore whether STAT4 gene polymorphism could become a predictive marker for SLE / LN risk. METHODS: Association studies were identified from the databases of PubMed, Embase, Cochrane Library and CBM-disc (China Biological Medicine Database) as of September 1, 2013, and eligible investigations were synthesized using meta-analysis method. RESULTS: 24 investigations were identified for the analysis of association between STAT4 gene polymorphism and SLE, consisting of 31190 patients with SLE and 43940 controls. In STAT4 rs7574865, there was a marked association between T allele or TT genotype and SLE susceptibility (T: OR=1.53, 95% CI: 1.30-1.79, P<0.00001; TT: OR=1.60, 95% CI: 1.34-1.92, P<0.00001), and GG homozygous was associated with SLE risk (OR=0.62, 95% CI: 0.51-0.75, P<0.00001). Furthermore, rs8179673, rs7582694, or rs3821236 minor allele frequency was associated with the risk of SLE, but this association was not found in rs16833431, rs11889341, rs10168266, rs7601754, however, the number of included studies was small and the results were less robust. In addition, STAT4 rs7574865 gene polymorphism was not associated with the LN risk. CONCLUSIONS: Our results indicate that T allele or TT homozygous is a significant risk genetic molecular marker to predict the SLE susceptibility and GG genotype is a valuable marker to against the SLE risk, but the association was not found for LN. However, more investigations are required to further clarify the association of the T allele or TT homozygous with SLE / LN susceptibility. This article is protected by copyright.
