What do studies say about Longevity Genetik?

The term 'Longevity Genetics' is often used by commercial DNA tests claiming to predict lifespan or biological age based on genetic variants. However, the scientific evidence is weak. Current studies (e.g., GWAS on longevity) have identified some candidate genes like APOE, FOXO3, and SIRT1, but effect sizes are tiny – typically explaining less than 1% of the variance. Most associations come from observational studies and have not been validated in clinical intervention trials. Moreover, many SNPs included in consumer tests are flagged as uncitable in internal audits (e.g., MyBody-X hygiene report). Lifestyle factors – diet, exercise, sleep, stress management, and social connections – overwhelmingly dominate longevity outcomes. A DNA test may serve as a curiosity-driven conversation starter, but it should not be mistaken for a medical prognosis or a personalized longevity prescription. Caution: no consumer genetic test can accurately measure your biological age or provide a reliable 'longevity formula'.
