Relationship between Angiotensin II Type 1 Receptor (AT1R) A1166C gene polymorphism and renal scarring risk is still controversial. This meta-analysis was performed to evaluate the association of AT1R A1166C gene polymorphism and renal scarring risk susceptibility. A predefined literature search and selection of eligible relevant studies were performed to collect data from electronic databases of PubMed, Embase and Cochrane Library. Three literatures were identified and included for the analysis of the relationship between AT1R A1166C gene polymorphism and renal scarring risk. We found that AT1R A1166C gene polymorphism was not associated with renal scarring susceptibility using the comparison of patients with scarring vs patients without scarring (C: OR=1.33, 95%CI: 0.83-2.13, P=0.23; CC: OR=1.71, 95%CI: 0.22-13.56, P=0.61; AA: OR=0.69, 95%CI: 0.39-1.21, P=0.20). Furthermore, AT1R A1166C gene polymorphism was also not associated with renal scarring risk using the comparison of patients with scarring vs healthy control. In conclusion, AT1R A1166C gene polymorphism was not associated with renal scarring risk susceptibility. However, more studies should be performed in the future.
