However, the scientific evidence is far more cautious: these variants reduce the activity of the methylenetetrahydrofolate reductase enzyme, which is involved in folate metabolism. Reduced activity can lead to elevated homocysteine levels when folate intake is low – a known risk factor for cardiovascular events. But: most carriers have no health issues, and evidence for direct causal links to the claimed conditions is weak or contradictory. Many direct-to-consumer tests overstate clinical relevance. Testing is only useful in the context of a medical workup for elevated homocysteine or specific risk factors. Routine supplementation with methylfolate is not evidence-based and may even carry risks. Bottom line: MTHFR is a prime example of the gap between mechanistic plausibility and clinical evidence.","area":"gesundheit","canonical_id":"gesundheit:canonical-b706a0b1481fc86bdb5a290b","id":"public-029cc2777a7f2b9c5ab9f724","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Lay opinion vs evidence: MTHFR Labor","score":38.72107571,"snippet":"MTHFR genetics (especially C677T and A1298C variants) is often portrayed in lay circles as a major cause of fatigue, depression, thrombosis, or miscarriage.
