Xie W et al (2012), showed the presence of a
differentially methylated region in the promoter of Vwde. The DMR spans 135 bp
(13,174,720-13,174,854;mm9 build) and contains 7 CpG dinucleotides which are paternally methylated.
However, the authors did not find presence of any active histone mark and/or preferential
transcription from the maternal allele.
