ObjectiveTo evaluate the relationship between A46G and C79G polymorphisms in the β2-adrenergic receptor (ADRB2) gene and the incidence of essential hypertension (EH) among the Han Chinese population.MethodsWe conducted a computer retrieval of PUBMED, EMBASE, CNKI, Wanfang and VIP databases prior to May 2010. Articles investigating the relationship of EH and ADRB2 gene polymorphism of Han group were found through literature search, including 15 articles on A46G and 10 articles on C79G. According to the including and excluding criteria, a Meta-analysis was conducted in EH and ADRB2 gene polymorphism of A46G and C79G. The association was examined by RevMan4.2 software through quantitative analysis.ResultsEight articles on A46G polymorphism (including 1078 EH cases and 788 control subjects) and six articles on C79G polymorphism (including 1367 EH cases and 1006 control subjects) were included in the current study. Meta-analysis showed that there was a significant association between A46G polymorphism and EH: genotype GG/(AA + AG) (fixed-effected model, OR = 1.35, 95%CI = 1.04 - 1.74, P = 0.02), genotype GG/AA (fixed-effected model, OR = 1.41, 95%CI = 1.06 - 1.89, P = 0.02). No significant association was found between C79G polymorphism and EH of Han group in China: G/C allele comparison (random-effected model, OR = 0.88, 95%CI = 0.55 - 1.39, P = 0.57).ConclusionSignificant association was found between A46G polymorphism of ADRB2 gene and EH, whereas no association could be found between C79G polymorphism and EH among Han Chinese population.
