Taking rs7119375 as an example, the odds of having hypertension was 2.46 (95% confidence interval (95% CI): 2.06-2.94), 2.82 (95% CI: 2.29-3.46) and 3.97 (95% CI: 2.37-6.64) under additive, dominant and recessive models (P<0.001), respectively, whereas the adjusted risk estimates were slightly attenuated but still significant.
Via sequencing the genes of apelin/angiotensin receptor-like 1 (apelin/APJ) pathway, we have recently identified and validated four common polymorphisms (rs3761581, rs56204867, rs7119375, and rs10501367) implicated in the development of hypertension.
Haplotype analysis indicated that haplotypes C-C-G-G (in order of T-1860C, rs3761581, rs7119375 and rs10501367) [adjusted odds ratio (ORadjusted) = 1.67, P = 0.0061] and T-A-A-A (ORadjusted = 1.62, P = 0.0008) conferred an increased risk for hypertension after adjustment for age, onset age, body mass index (BMI) and waist-to-hip ratio, whereas haplotype C-C-A-A (ORadjusted = 0.33, P = 0.0048) conferred a protective effect.
Three SNPs (rs7119375, rs10501367 and rs9943582) within AGTRL1 were found to be associated with hypertension, BMI and the onset age of hypertension, whereas after correction, only marginal associations were noted.
