Genes That Influence the Body’s Internal Clock

Polymorphisms in core clock genes may contribute to individual differences in circadian rhythm expression.

• Core clock genes form a feedback loop that regulates gene transcription and translation.
• The genetic clockwork generates circadian rhythms in various cells throughout the body.
• Individual variations in circadian rhythms are linked to differences in genetic makeup.
• The circadian clock influences gene expression patterns and cellular functions.
• Genetic factors related to circadian rhythms may play a role in normal physiological processes and disease development.
