Can APOE help with Langlebigkeit?

APOE is best known for its role in Alzheimer's disease and lipid metabolism. The ε4 allele increases risk for late-onset Alzheimer's and cardiovascular issues, potentially shortening lifespan. The rarer ε2 allele may offer slight protection. However, the overall effect on longevity is modest and heavily modulated by diet, exercise, and other lifestyle factors. GWAS have linked APOE variants to human lifespan, but the effect sizes are small and not deterministic. A consumer DNA test cannot predict your longevity. Evidence is human-moderate: associations are real but not strong enough for individual prediction. Be cautious of marketing claims that overstate APOE's role. Longevity is polygenic and multifactorial; no single gene decides it.
