In this Han Chinese population, the -344T/C polymorphism of the CYP11B2 gene was found to be associated with EH and glucose homeostasis, both of which might be mediated by plasma aldosterone levels, insulin sensitivity and β-cell function.
Aldosterone synthase (CYP11B2) is one of the most studied candidate genes related to essential hypertension (EH) and left ventricular hypertrophy (LVH).
Our results suggest that the down-regulation of ANP gene expression at mRNA and protein levels and up-regulated CYP11B2 protein expression levels may be correlated with the essential hypertension and could serve as circulating prognostic biomarkers for essential hypertension.
When subgrouped by sex, males with the t allele of REN Taq I had decreased risk for EH (OR: 0.529), and those with AGT -6G and CYP11B2 -344 C had increased risk for EH (OR: 1.498; 1.449).
Our study suggests that there is lack of association between C-344T polymorphism of CYP11B2 gene and EH in Dongxiang and Han populations, whereas the polymorphism was correlated with EH in female population of Tibetan.
Among individuals with essential hypertension certain relationships were documented between rs5182 and rs5186 polymorphisms of AGTR1 gene and rs1799998 polymorphism of CYP11B2 gene on one hand and the volume of carotid bodies on one other.
This case-control study was aiming to investigate the relationship between the aldosterone synthase gene (CYP11B2) biallelic polymorphism in the promoter at position -344 (-344C/T) with essential hypertension and left ventricular hypertrophy in the Egyptian population.
