The evidence, however, is weak and mixed. While MTHFR polymorphisms (C677T, A1298C) can reduce enzyme activity and affect folate metabolism, large-scale studies and meta-analyses have not confirmed a causal link to neurodevelopmental disorders. Professional guidelines (AAP, ACMG) advise against routine MTHFR testing in children because results lack clinical utility: they do not change management, and may cause unnecessary worry or false reassurance. Some practitioners recommend methylfolate supplementation based on MTHFR status, but randomized controlled trials show no benefit for autism or ADHD symptoms. The only potential relevance is in rare cases of severe hyperhomocysteinemia, which is not detected by standard DTC panels. In summary, MTHFR testing in children is not evidence-based; it is a classic example of marketing over science. Parents should focus on standard pediatric care and consult a physician for specific symptoms.","area":"gesundheit","canonical_id":"gesundheit:canonical-6b7579980f68e91233ae69a5","id":"public-061261cc306f0dcfe3a14aaf","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Lay opinion vs evidence: MTHFR Kinder","score":40.98935812,"snippet":"Lay opinion often portrays MTHFR variants in children as a root cause of autism, ADHD, or digestive issues, fueled by DTC marketing.
