What role does ADH1B play in menopause?

The provided context contains no evidence regarding the role of ADH1B in menopause. ADH1B encodes an alcohol dehydrogenase enzyme involved in ethanol metabolism. Some population-based studies have explored links between ADH1B variants and estrogen levels or age at menopause, but the evidence is weak and insufficient for clinical guidance. Without specific data from the MyBody-X knowledge base, no reliable conclusion can be drawn. The evidence rating is 'unclear'.
