Meta-analysis results of epigenome-wide association studies in neonates reveals widespread differential DNA methylation associated with birthweight

<p>Birthweight is associated with health outcomes across the life course, DNA methylation may be an underlying mechanism. In this meta-analysis of epigenome-wide association studies of 8,825 neonates from 24 birth cohorts in the Pregnancy And Childhood Epigenetics Consortium, DNA methylation in neonatal blood is associated with birthweight at 914 sites, with a difference in birthweight ranging from -183 to 178 grams per 10% increase in methylation (P_Bonferroni&lt;1.06x10^-7).</p>
