DNAmAge

Meaning

DNAmAge, or DNA methylation age, is a quantifiable measure of an individual’s biological age derived from analyzing specific patterns of DNA methylation across the genome, serving as a robust epigenetic biomarker of aging. This molecular clock, developed by researchers like Steve Horvath, provides a more accurate reflection of physiological decline and mortality risk than chronological age alone. Clinically, calculating DNAmAge allows practitioners to assess the pace of an individual’s aging process, offering a powerful tool for monitoring the efficacy of longevity interventions and lifestyle modifications. A discrepancy where DNAmAge exceeds chronological age, known as age acceleration, signals a heightened vulnerability to age-related diseases.
