It is best known for its role in warfarin sensitivity. Some consumer DNA tests claim that VKORC1 variants are linked to longevity, because vitamin K influences blood clotting, bone metabolism, and vascular health. However, the scientific evidence for a direct connection between VKORC1 polymorphisms and human longevity is weak. No large GWAS have identified VKORC1 as a significant longevity marker. The proposed effects are purely mechanistic and indirect (e.g., via vitamin K status and arterial calcification). Moreover, vitamin K status is heavily influenced by diet and gut microbiome. A DNA test alone cannot predict lifespan. Claims that VKORC1 is a 'longevity gene' are more marketing than evidence-based science. Clinically, VKORC1 testing (e.g., rs9923231) is relevant for warfarin dosing, not for longevity. Lifestyle factors such as exercise, diet, and smoking cessation have a far greater impact on lifespan.","area":"gesundheit","canonical_id":"gesundheit:canonical-72895c78ab08f3b01a296285","id":"public-4f16c96ddc628cc28a335250","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs facts: VKORC1 and longevity","score":31.65451043,"snippet":"VKORC1 encodes vitamin K epoxide reductase, a key enzyme in the vitamin K cycle.

Einige Varianten (z.B. rs9923231) verändern die Enzymaktivität und damit die Vitamin-K-Verfügbarkeit. In der Alternsforschung wird spekuliert, dass eine optimierte Vitamin-K-Versorgung über VKORC1 die arterielle Elastizität und Knochengesundheit fördern könnte – beides Faktoren, die mit Langlebigkeit assoziiert sind. Allerdings gibt es keine robusten Humanstudien, die einen direkten kausalen Zusammenhang zwischen VKORC1-Varianten und einer verlängerten Lebensspanne belegen. Die Evidenz ist überwiegend mechanistisch und basiert auf indirekten Effekten (z.B. Matrix-Gla-Protein). Viele kommerzielle DNA-Tests bewerben VKORC1 als „Langlebigkeitsgen“, was eine Übertreibung darstellt. Die tatsächliche Relevanz für die individuelle Lebenserwartung ist gering, da Ernährung, Bewegung und andere Gene (z.B. FOXO3, APOE) weitaus stärker ins Gewicht fallen. Fazit: VKORC1 ist kein direktes Langlebigkeitsgen; die Evidenz ist schwach und marketinggetrieben. Eine ausgewogene Vitamin-K-Zufuhr (grünes Blattgemüse) ist sinnvoll, aber eine Gen-basierte Supplementierung nicht empfohlen.","area":"gesundheit","canonical_id":"gesundheit:canonical-04edee8d6a4651a947c6f222","id":"public-17fdfd6c5010364fb9625d43","kind":"qa","language":"de","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs Facts: VKORC1 und longevity","score":31.51084299,"snippet":"VKORC1 ist ein zentrales Gen im Vitamin-K-Stoffwechsel und beeinflusst die Blutgerinnung sowie die Kalzifizierung von Gefäßen.
