Genes significantly influence human lifespan, accounting for about 25% of variation. Ongoing research uses molecular biology and centenarian studies to identify specific genes affecting longevity and disease development.

Area of Science:

  • Genetics
  • Gerontology
  • Epidemiology

Background:

  • Human lifespan is influenced by genetic factors, as evidenced by family and twin studies.
  • Approximately 25% of lifespan variation is attributed to genetic determination.
  • Centenarian studies and molecular biology advancements enable the search for longevity-associated genes.

Purpose of the Study:

  • To review the literature on the influence of genes on human longevity.
  • To discuss common factors affecting disease development and lifespan.
  • To explore methodological challenges and propose new approaches in longevity epidemiology.

Main Methods:

  • Review of existing literature on genes and longevity.
  • Analysis of family, twin, and centenarian study data.

  • Discussion of molecular biology techniques for gene identification.

    • Main Results:

    • Genetic factors play a significant role in determining human lifespan.
    • Identification of candidate genes influencing longevity is an active area of research.
    • The polygenic nature of lifespan and historical mortality changes present epidemiological challenges.

    Conclusions:

    • Genes are a key determinant of individual survival and longevity.
    • Further research is needed to understand the complex genetic architecture of aging.
    • Novel methodological approaches are required to address the complexities in longevity studies.
