Evidence check: CLOCK in the context of menopause

CLOCK (Circadian Locomotor Output Cycles Kaput) is a core circadian gene. During menopause, circadian disruption is common, and some studies link CLOCK variants to sleep quality, hot flashes, or mood changes. However, effect sizes are small, and evidence is mostly from GWAS or observational studies. A genetic test cannot diagnose menopause-related issues or predict severity. Lifestyle, hormone levels, and environment are far more influential. Caveat: No clinically validated cutoffs exist for CLOCK SNPs in the menopause context. Results should be considered exploratory, not actionable.
