Intergenerational association of DNA methylation between parents and offspring.

ABSTRACT: Early patterning of DNA methylation (DNAm) may play an important role in later disease development. To better understand intergenerational epigenetic inheritance, we investigated the correlation between DNAm in blood in mother-newborn and in father-newborn pairs in the Isle of Wight (IoW) birth cohort. For parent-newborn pairs (n = 48), offspring DNAm was measured in cord blood and the parent's DNAm in whole blood. Mothers' DNAm was analyzed at birth (Guthrie card), age 18, early and late pregnancy respectively, and fathers' DNAm was measured during the mother's pregnancy. Linear regressions were applied to assess the intergenerational correlation of parental DNAm with that of offspring. Among various pairs of mother-newborn and father-newborn DNAm, the pairs where the mothers' DNAm was me
