Association of angiotensinogen gene M235T polymorphisms with essential hypertension：a meta-analysis / 重庆医学

ABSTRACT

Objective To evaluate the association of angiotensin (AGT ) gene M235T polymorphism with essential hypertension (EH) .Methods The literatures examining the association of the M 235T polymorphisms with EH were selected in electronic data-bases .Using RevMan5 .0 ,heterogeneity and pooled effect sizes were calculated .Results Totally ,29 articles ,with 5 971 cases and 6 443 controls were finally included in this study .The odds ratio (OR) value of TT+ TM∶MM genotype was 1 .13 (95% CI 1 .00-1 .25 ,P=0 .04) in worldwide populations .Subgroup analysis showed that the OR values of TT ∶MM genotype were 1 .13 (95% CI 0 .90-1 .42 ,P=0 .28) in subjects published before 2008 and 1 .29(95% CI 0 .94-1 .75 ,P=0 .11) in those after 2008(year of 2008 included) .The OR values of T ∶M in Han population was 1 .24 (95% CI 1 .01-1 .53 ,P=0 .04) .Conclusion TT+ TM genotype of the M235T polymorphisms is associated with EH in worldwide populations ,and T allele is also correlated with EH in Han popu-lation .
