The effect of periconceptional micronutrient supplementation on offspring DNA methylation

ABSTRACT: The effect of pre and periconceptional multiple micronutrient supplementation on methylation of CpG loci within CpG islands associated with 14,000 genes across the human genome has been investigated in the offspring of a cohort of Gambian women participating in a controlled double blinded trial. Methylation levels in placebo and micronutrient supplemented cohorts were compared in genomic DNA from cord blood (35 placebo and 21 micronutrient supplemented) and in circulating blood samples (14 placebo and 9 micronutrient supplemented) drawn from the same cohort at 9 months old. A small number of differentially methylated CpG loci were identified in cord blood (14 in males and 21 in females) and a larger number in the 9 month infant comparison (108 in males and 106 in females). Seven differenti
