In dried blood spots, >90th percentile PFOA concentration correlated with DNA methylation CpG near SCRT2, SRXN1; >90th percentile PFOS concentration was related to a CpG in GVIN1 in boys and a CpG in ZNF26 in girls). Log-scaled, continuous PFOS concentration associated with methylation of CpG in PTBP1, a gene associated with cardiovascular disease and development. This evidence concerns the gene SCRT2 and cardiovascular disorder.
