Approved research

Unravelling the determinants of successful ageing by examining longevity

Principal Investigator: Dr Karen Mather
Approved Research ID: 53850

Lay summary

Exceptionally long-lived individuals often delay or escape common age-related diseases and can be seen as models of successful ageing. Exceptional longevity is moderately heritable suggesting genetic factors plays a role in determining survival. Therefore, these individuals can be used to study the influence of genetics on successful ageing. Examining the genetic overlap between exceptional longevity and different traits (e.g. Alzheimer's disease, protein levels) may reveal novel phenotypes and common pathways linked to successful ageing. This project aims to identify the different genetic factors and pathways associated with longevity/successful ageing. In the UKB, longevity data is not available for the majority of participants so parental longevity will be used as a proxy. Other longevity-related traits will also be investigated, including healthy longevity, which will be defined as parental longevity plus the absence of common diseases. The duration of the project will be three years. The results of this project will increase our knowledge of the factors associated with exceptional longevity and successful ageing and may facilitate innovative strategies to promote health in our ageing population.
