5-hydroxymethylcytosine is enriched at paternally methylated secondary DMRs. Average 5hmC levels and standard deviations for primary DMRs associated with the paternally methylated H19-ICR, the maternally methylated Snrpn DMR, the paternally methylated H19-pp and Cdkn1c DMRs and the maternally methylated Ndn and Peg12 DMRs in DNA derived from 9.5 and 14.5 d.p.c. embryos and from 5 d.p.p. and adult liver
