Epigenetic Clock

Meaning

The Epigenetic Clock is a biochemical measure of biological age that estimates the chronological age of a tissue or organism by analyzing the pattern of DNA methylation at specific genomic sites. This measure often deviates from chronological age, providing a more insightful indicator of an individual’s cumulative exposure to physiological stress and environmental factors. Clinically, the difference between biological and chronological age, termed age acceleration, is a powerful biomarker correlated with all-cause mortality and various age-related diseases.
