  1. Bold indicates significance p < 1 × 10−6. Probes were annotated with the most proximal gene, genomic position Bp (hg19), and CpG island context (CGI feature)
  2. Estimate intra-pair difference in M value (logit-transformed beta), FDR false discovery rate < 0.05, TSS200 region spanning from transcription start site (TSS) to 200 bp upstream of TSS, TSS1500 region spanning from − 200 to − 1500 bp upstream of TSS, 5′UTR 5′ untranslated region, IGR intergenic region, NA not applicable, Hyper hyper-methylation, Hypo hypo-methylation
  3. aRelative DNA methylation of “inferior” twin compared to “superior” twin
