Overview

• CheekAge, an epigenetic clock, measures biological aging through a simple cheek swab.
• The test was validated using blood samples from over 1,500 elderly participants in the Lothian Birth Cohorts study.
• For each standard deviation increase in CheekAge versus chronological age, the risk of death rose by 21%.
• Key DNA markers, such as ALPK2 and PDZRN4, were identified as significant predictors of mortality.
• CheekAge's performance in predicting mortality outpaced several established blood-based epigenetic clocks.
