Abstract
A personalized healthy aging program, aimed at preservation of functional capacities in old ages, should consider genetic (hereditary) factors that determine the structure and functions of body organs and systems, and their age-related changes. Individual genetic characteristics of a person can influence the aging process. For this reason, recent research focuses on identifying genetic mechanisms of aging and longevity associated with multifactorial diseases. Renin-angiotensin system (RAS) contributes to the development of pathological conditions leading to cardiovascular diseases, cognitive changes, disorders of auditory and visual analyzers, and may determine the preservation of functional capacities in older adults. We present a literature review of the role of the RAS gene polymorphisms in the aging processes. The results of the synthesis of Russian and international literature indicated the contribution of polymorphic variants of the angiotensinogen (AGT), angiotensin-converting enzyme (ACE), and angiotensin II receptor type 1 (AGTR1) genes to the development of pathological conditions and the associated decreases in functional capacities of an elderly person. Testing for these polymorphisms can be of a practical importance for personified health assessment and development of timely preventive interventions aimed at improving life expectancy and quality of life among older adults.
