Biological ageing estimators derived from DNA methylation data are heritable and correlate with morbidity and mortality. We report 137 genome wide significant loci (113 novel) via meta-analyses of six DNA methylation-based (DNAm) biomarkers in 34,962 European-ancestries and 6,482 African American individuals. Several DNAm biomarkers exhibit strong genetic correlations with multiple health and lifestyle measures. Polygenic scores explained up to 4.2% of the variance and the score for a DNAm estimator of mortality risk, DNAmGrimAge, was associated with parental longevity, education, and adiposity-related traits. Overall, this study greatly advances our understanding of the genetic determinants of epigenetic ageing processes in human blood. ### Competing Interest Statement The authors have declared no competing interest.
