COMT (catechol-O-methyltransferase) degrades dopamine and norepinephrine; the common Val158Met variant (rs4680) is linked to altered stress sensitivity and cognitive performance, but effects on fatigue are small, inconsistent, and heavily modulated by sleep, diet, and stress. Direct-to-consumer tests marketing COMT as a 'fatigue gene' overstate clinical utility. Evidence is primarily mechanistic and from GWAS, not from controlled intervention trials. Fatigue is multifactorial – hormones, microbiome, nutrient status, and lifestyle are more impactful than a single gene. A COMT test alone provides no actionable insight. Safety note: Not a medical diagnosis; persistent fatigue warrants clinical evaluation.","area":"gesundheit","canonical_id":"gesundheit:canonical-6ee99fb2976461aa377d2c11","id":"public-3dea8d69fd59fdc7c34cfee7","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: COMT in the context of Müdigkeit","score":21.67798304,"snippet":"The provided MyBody-X knowledge does not include COMT markers.

These direct-to-consumer nutrigenetic tests analyze gene variants linked to nutrient metabolism or energy pathways (e.g., MTHFR, FTO, COMT). However, effect sizes are small, and clinical relevance for everyday fatigue is unproven. Fatigue has many causes: poor sleep, stress, iron deficiency, thyroid issues, depression, or chronic infections. A DNA test alone cannot diagnose these. Evidence for personalized supplement recommendations from such tests is mostly marketing or mechanistic. Without blood work (e.g., ferritin, vitamin D, B12) and medical evaluation, the utility is questionable. Bottom line: The test may offer lifestyle inspiration but does not replace clinical diagnostics. If you suffer from persistent fatigue, consult a doctor first.","area":"gesundheit","canonical_id":"gesundheit:canonical-b2ec2c1ea6c6dcdffb7f5f33","id":"public-7ff5daf29403ea6f179375e7","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: NutriCare | INFINITY DNA-Test in the context of Müdigkeit","score":19.83982608,"snippet":"The NutriCare or INFINITY DNA test from MyBody-X is marketed for fatigue, but the scientific evidence is weak.

Such tests typically analyze single gene variants (e.g., FTO, MC4R, PPARG) associated with a small increased risk of obesity – effect sizes are tiny (GWAS p often >5e-8, beta <0.1). Fatigue is multifactorial: poor sleep, stress, iron deficiency, thyroid issues, vitamin D deficiency, or psychological factors. A DNA test cannot assess these. Evidence for personalized diet based on these genes is insufficient; randomized trials show little clinically meaningful benefit. MyBody-X tests are screening tools, not diagnostic.
