Conclusion. There is a significant relationship between the studied polymorphic variants of the APOC3, PON1, AGT, AGTR1 genes and vascular control parameters in the context of orthostasis. It may be a predictor of early development of arterial hypertension.

The genetic architecture of blood pressure (BP) includes more than 30 genes, the polymorphic variants of which cause phenotypic heterogeneity of BP. Given that a human genetic information is largely stable from birth, it can act as an early predictor of hypertension (HTN). Identification of polymorphic variants of genes associated with a high HTN risk may be one of the promising areas of early diagnosis and prevention of this disease. In addition, the availability of this data will make it possible to clarify the prognosis of patients already with HTN, as well as to personalize the treatment approach. The review analyzes the papers devoted to the molecular genetic basis of hypertension and identifies the possible role of gene polymorphism of the renin-angiotensin-aldosterone system in hypertension development. A large number of studies have revealed an association between HTN and polymorphic variants of the ACE, AGT, AGTR1 genes. In addition, polymorphism of these genes is involved in the development of atherosclerosis and related diseases, kidney and central nervous system disorders, and justifies the effectiveness of angiotensin-converting enzyme inhibitors in the treatment of HTN.
