E-selectin gene polymorphism (A561C) and essential hypertension. Meta-analysis in the Chinese population
1School of Public Health of Guangxi Medical University, 22 Shuangyong Road, Nanning, Guangxi, China.
Background:
The A561C polymorphism of the E-selectin gene (SELE) has been reported to be associated with essential hypertension (EH) in several studies; however, results among these studies were inconsistent. Here, we conducted a meta-analysis to explore the association of the A561C polymorphism with EH.
Methods:
Publications were retrieved through searching PubMed, Web of Science, the China National Knowledge Infrastructure (CNKI), China Biological Medicine, and the Wanfang database. Odds ratios (OR) and 95 % confidence intervals (CI) were calculated to estimate the strength of association of A561C with EH. Subgroup analysis was also performed to assess ethnic discrepancies. A total of seven studies comprising 2,127 EH patients and 2,078 controls were analyzed.
Results:
In the dominant model analysis, we found significant associations between the A561C polymorphism and EH in all subjects (CC+AC vs. AA, OR = 1.96, 95 %CI 1.57-2.44, P heterogeneity = 0.381), in a Han Chinese subgroup (CC+AC vs. AA, OR = 2.38, 95 %CI 1.73-3.29, P heterogeneity = 0.269), and in non-Han Chinese minorities (CC+AC vs. AA, OR = 1.62, 95 %CI 1.19-2.21, P heterogeneity = 0.84).
Conclusion:
The findings suggest that C allele carriers of the SELE gene polymorphism (A561C) might be predisposed to EH in the Chinese population. Further investigations in other ethnic populations should be conducted to verify these findings.
