Methylation levels of candidate genes versus birth weight. "Beta value" is fraction of methyl C observed at the PGRMC1 (CpG ID: cg19606309) site (A) and RGS14 (CpG ID: cg09010421) site (B) on Illumina GoldenGate array in placenta (n = 22, in duplicate). Methylation levels assayed at same site by bisulfite pyrosequencing also correlated with birth weight for PGRMC1 (C) and RGS14 (D) in placenta (n = 13).
