DunedinPACE (Pace of Aging, Computed from the Epigenome) is a third-generation blood DNA methylation biomarker developed by Belsky, Caspi, and Moffitt from the longitudinal Dunedin Study cohort. Unlike first-generation (Horvath, Hannum) and second-generation (PhenoAge, GrimAge) clocks which measure biological age as a static odometer, DunedinPACE functions as an instantaneous speedometer—quantifying the biological pace of deterioration per chronological year across 19 multi-organ physiological biomarkers. A DunedinPACE score of 1.0 indicates aging at the expected chronological pace, whereas scores below 0.8 indicate a decelerated pace of aging associated with markedly lower morbidity and mortality.

DunedinPACE, a DNA methylation biomarker of the pace of aging
“DunedinPACE demonstrated high test-retest reliability (ICC = 0.96) and showed that individuals aging faster had accelerated decline in physical function, cognitive capability, and facial aging, as well as increased risk of chronic disease and mortality.”

“Requires standardized capillary or venous blood sampling; technical batch effects and seasonal variations require careful laboratory quality control.”
