The Claim

In individuals of European descent, 25 genetic loci are associated with parental longevity, with 10 reaching genome-wide significance for combined parental attained age. These loci include variants near or within the APOE, CHRNA3, LPA, CDKN2B-AS1 (ANRIL), and SH2B3/ATXN2 genes, indicating that human longevity is a highly polygenic trait influenced by multiple common genetic variants with small individual effects.

In plain English

Scientists found 25 spots in the DNA of people with European roots that are linked to how long their parents lived — some of these spots are near genes we already know affect aging, and it looks like living a long life is shaped by lots of little genetic factors working together.

What the research says

1 study

  1. Study: Human longevity: 25 genetic loci associated in 389,166 UK biobank participants

    The study looked at genes in people of European ancestry and found that many small genetic differences, including in some of the same genes mentioned in the claim, are linked to how long their parents lived. This supports the idea that living a long life runs in families because of lots of little genetic factors.
