Time matters: circadian genetics and the molecular logic of human health and disease.

Genetic variation and misalignment of the circadian clock significantly influence human health, disease risk, and treatment outcomes, highlighting the importance of temporal biology.

• Why it matters: Understanding how the circadian system impacts physiology and disease is crucial because time is a key but often overlooked factor in health management and therapeutic strategies.
• What they did: The review synthesizes recent advances in circadian genetics and molecular mechanisms, including the evolution from a linear feedback loop to a complex, dynamic network, and discusses future research priorities.
• The result: These insights enable the development of disease-specific models and new tools to modulate circadian pathways, paving the way for more precise, time-aware medical interventions.
