The role of NOS3 (rs2070744) and GNB3 (rs5443) genes' polymorphisms in endothelial dysfunction pathway and carotid intima-media thickness in hypertensive patients.

The mechanisms orchestrating the balance between nitric oxide and endothelium-derived contracting factors, and genetic predisposition to endothelial dysfunction in hypertensive patients remain to be determined. One-hundred hypertensive patients participated in the case-control study to clarify the risk of endothelial dysfunction and carotid "intima media" thickness (IMT) changes depending on NOS3 (rs2070744) and GNB3 (rs5443) genes' polymorphisms. It is found that presence of NOS3 gene's С-allele significantly elevates the risk of atherosclerotic plaques on carotid arteries (OR95%CI: 1.

The cytochrome 11B2 aldosterone synthase gene rs1799998 single nucleotide polymorphism determines elevated aldosterone, higher blood pressure, and reduced glomerular filtration, especially in diabetic female patients.

Objective: The cytochrome 11B2 aldosterone synthase gene (CYP11B2) that links to aldosterone synthase enzyme synthesis changes and blood pressure regulation is of particular interest among the renin-angiotensin-aldosterone system encoding genes.

Methods: One-hundred hypertensive patients with target-organ damaging (2nd stage), moderate, high or very high cardiovascular risk were involved in the case-control study. Mean age was 59.
