Lack of Association of ACE2 G8790A Gene Mutation with Essential Hypertension in the Chinese Population: A Meta-Analysis Involving 5260 Subjects.

ABSTRACT: BACKGROUND: The angiotensin converting enzyme 2 (ACE2) G8790A gene polymorphism has been associated with the susceptibility to essential hypertension (EH), but the results are disputable. OBJECTIVE AND METHODS: To investigate the relationship between the ACE2 G8790A gene polymorphism and EH, eight separate studies with 5260 subjects were meta-analyzed. The pooled odds ratio (OR) and its corresponding 95% confidence interval (CI) were calculated by a random effect model. RESULTS: In the ACE2 G8790A gene polymorphism and EH meta-analysis in a Chinese population, no significant association was found between the ACE2 G8790A gene polymorphism and EH (OR: 1.03, 95% CI: 0.87-1.21, P?=?0.76). In the stratified analysis by gender, no significant risk was found among males (OR: 1.06, 95% CI: 0.82-1.36, P?=?0.66) or females (OR: 0.98, 95% CI: 0.77-1.24, P?=?0.85). Under a dominant model of inheritance in the female subgroup, the pooled OR for the GG/GA?+?AA value was 1.01 (95% CI: 0.82-1.25, P?=?0.92). Under a recessive model of inheritance in the female subgroup, the pooled OR for the AA/AG?+?GG value was 0.93 (95% CI: 0.50-1.73, P?=?0.83). CONCLUSION: The current meta-analysis suggested that the ACE2 G8790A gene polymorphism might not be related to the increased EH risk in the Chinese population.
