RETRACTED: Association of aldosterone synthase ( CYP11B2 ) gene polymorphism with IgA nephropathy risk and progression of IgA nephropathy

Abstract

OBJECTIVE: This meta-analysis was conducted to assess the association of aldosterone synthase (CYP11B2) gene polymorphism with the risk of immunoglobulin A (IgA) nephropathy (IgAN) and the progression of IgAN. METHODS: The literature on associations was identified from PubMed and the Cochrane Library on 1 October 2013, and eligible reports were synthesized. RESULTS: Eligible reports were recruited into this meta-analysis for the association of CYP11B2-344C/T (rs1799998) gene polymorphism with IgAN risk, and the progression of IgAN. In this meta-analysis, the association of CYP11B2-344C/T (rs1799998) gene polymorphism with IgAN risk was not found in overall populations and in Asians. Interestingly, the C allele and CC genotype were associated with the risk of IgAN in Caucasians, but the TT genotype was not. CONCLUSION: CYP11B2-344C/T gene polymorphism is not associated with IgAN risk and IgAN progression in overall populations and in Asians, but CYP11B2 C allele and CC genotype were associated with the risk of IgAN in Caucasians. However, more studies should be performed in the future to confirm this association.
