Is ADH1B useful for Müdigkeit?

ADH1B encodes alcohol dehydrogenase, an enzyme that metabolizes ethanol. Certain variants (e.g., rs1229984) cause rapid conversion of alcohol to acetaldehyde, leading to flushing, nausea, and discomfort. Regarding fatigue, ADH1B is only indirectly relevant if tiredness stems from alcohol consumption or hangover. There is no strong evidence that ADH1B testing predicts or explains general fatigue, chronic exhaustion, or energy levels in non-drinkers. The association is strictly alcohol-dependent. Without alcohol intake, the gene has no proven utility for fatigue management. MyBody-X may include ADH1B in an alcohol metabolism panel, but its clinical value for fatigue is minimal. Evidence: mechanistic/observational for alcohol metabolism, not for fatigue as a standalone symptom. Avoid overinterpretation.
