The study was conducted in 2022 and examines the hereditary predisposition to longevity by analyzing the pedigrees of 300 long-lived people who lived throughout their lives in the Carpathians (Ivano-Frankivsk region, Ukraine). The clinical and genealogical method is carried out in two stages. This is primarily the compilation of the pedigree and its graphic image, then genetic analysis of the data. It should be noted that all respondents were informed about the specifics of the study and gave written consent to the analysis of personal data. According to clinical and genealogical indicators, the predisposition to longevity with its implementation in the phenotype was in 72% of respondents and 1.8 times more often inherited from the maternal than paternal line (p <0.05).
