Relationship between TGF-ß1 + 869 T/C and + 915 G/C gene polymorphism and risk of acute rejection in renal transplantation recipients.

BACKGROUND: This meta-analysis was conducted to assess the relationship between the transforming growth factor-beta 1 (TGF-ß1) + 869 T/C gene polymorphism, + 915 G/C gene polymorphism, and the susceptibility of acute rejection in the recipients with renal transplantation. METHODS: Relevant studies were searched and identified from the Cochrane Library and PubMed, and eligible investigations were recruited and data were calculated by meta-analysis. RESULTS: In this study, we found no relationship between either TGF-ß1 + 869 T/C or TGF-ß1 + 915 G/C gene polymorphism and acute rejection susceptibility in patients with renal transplantation. No association between either gene polymorphism and acute rejection susceptibility in patients with renal transplantation in Caucasian, Asian, or African populations individually was found. CONCLUSION: The TGF-ß1 + 869 T/C and + 915 G/C gene polymorphisms are not associated with acute rejection susceptibility in recipients with renal transplantation.
