Imprinted gene methylation and age in disease-free women. Average methylation (%) within imprinted genes PLAGL1/ZAC1, RB1, H19-ICR1, SNRPN-DMR1, IGF2-DMR2, PEG3 and KvDMR-ICR2 according to age for all disease-free samples. Linear regression analysis fit shown with a solid line and with 95Â % CI shown with a dashed line. Average methylation levels are shown by an open circle. None of the associations were statistically significant. PLAGL1/ZAC1 pleomorphic adenoma gene like 1, RB1 retinoblastoma 1, H19 H19, imprinted maternally expressed non-coding transcript-imprint control region 1, SNRPN small nuclear ribonucleoprotein polypeptide N, IGF2 insulin-like growth factor 2, PEG3 paternally expressed gene 3, KvDMR 11p15 region imprint control region 2, CI confidence intervals
