Genome wide blood DNA methylation measured at birth and age 7 on the EPIC array

We measured the DNA methylation levels at ~800,000 CpG sites from ethnically admixed children in CBMCs at birth and PBMCs age 7 to study the longitudinal dynamics of methylation marks. We found that self-reported race-dependent methylation levels were conserved over time, which helped to suggest that blood methylation levels are robust to environmental exposures during the first 7 years of life. DNA methylation measured on the EPIC array in CBMCs at birth and PBMCs at age 7 from 196 children.
