ADH1B encodes alcohol dehydrogenase, which catalyzes the first step of ethanol metabolism. The well-studied variant rs1229984 (Arg48His) results in faster alcohol clearance and is associated with reduced risk of alcohol dependence. Some research suggests this variant may influence stress-induced drinking behavior, as fast metabolizers may experience less reinforcement from alcohol. However, evidence for a direct effect on stress physiology (e.g., cortisol response) is weak and inconsistent. Most data come from genetic association and epidemiological studies, not from randomized controlled trials. Therefore, the predictive value for individual stress management is limited. A DNA test for ADH1B cannot provide clinical guidance for coping with stress. Lifestyle factors such as sleep, exercise, and social support have a much larger impact.
