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.
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.
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.
Aldosterone synthase (CYP11B2) is one of the most studied candidate genes related to essential hypertension (EH) and left ventricular hypertrophy (LVH).
After 6 weeks, the results showed that the ACE I/D polymorphism, not the CYP11B2-344T/C polymorphism, was associated with systolic blood pressure (SBP) response to HCTZ (P = 0.009) in the Han Chinese population with essential hypertension, with no interaction.
To address this issue, we carried out a haplotype-based, case-control study to explore the association between a human CYP11B2 gene and essential hypertension (EH) in the southwest Han population of China (n = 1020 individuals).
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.
Current large sample analysis did not support the association between the etiology of essential hypertension and CYP11B2 - 344 C/T polymorphism in Han Chinese.
Interaction between the C(-344)T polymorphism of CYP11B2 and alcohol consumption on the risk of essential hypertension in a Chinese Mongolian population.
The intron-2 conversion polymorphism of CYP11B2 was suggested to lead to overexpression of the gene, and may therefore have potential to predict the blood pressure response of patients with essential hypertension to angiotensin-converting enzyme inhibitors (ACEIs).
Although polymorphisms in renin-angiotensin-aldosterone (RAA) system genes for angiotensinogen (AGT M235T), angiotensin-converting enzyme (ACE I/D), angiotensin II type 1 receptor (AT1 A/C1166), and aldosterone synthase (CYP11B2-344T/C) have been major targets for genetic investigation in association with essential hypertension (EH), the influence of these genetic factors is still to be determined.
