Methylation levels of candidate genes versus birth weight. "Beta value" is the fraction of methyl C observed at the ANGPT4 (CpG ID: cg26540515) site (A) in placenta and PRSS21 (CpG ID: cg21085768) site (B) in cord blood on the Illumina Infinium array (n = 48). Methylation levels assayed at same site by bisulfite pyrosequencing also correlated with birth weight for ANGPT4 (C) in placenta (n = 26) and PRSS21 (D) in cord blood (n = 25).
