How are CLOCK and Wechseljahre related?

The CLOCK gene is a core component of the circadian rhythm machinery. Menopause (Wechseljahre) involves hormonal shifts that can disrupt sleep and daily rhythms. Research suggests that CLOCK gene variants may influence the timing of menopause and the severity of symptoms like hot flashes and sleep disturbances. However, the evidence is moderate and largely based on observational studies; no direct causal pathway has been firmly established. Genetic testing for CLOCK in the context of menopause remains investigational and is not a standard clinical tool.
