Proportion of variance of genome-wide DNA methylation levels attributed to genetic variation. Estimates for the 723,814 CpGs sites covered by the EPIC array after a classical twin study of 88 MZ and 70 DZ twin pairs from the TwinsUK cohort. a Cumulative proportion of variance components of the ACE model: variance explained by additive genetic effects, or heritability (A), common environmental effects (C) and nonshared environmental effects (E). b Cumulative proportion of heritability estimates by genomic annotations
