Xie W et al (2012), showed the presence of a
differentially methylated region in the promoter of Vwde (also knows as Mis-1or Mlvi-1; or
Gt(pU21)84Imeg). The DMR spans 161 bp (61,868,725-61,868,885;mm9 build) and contains 10 CpG
dinucleotides which are maternally methylated. However, the authors did not find presence of any
active histone mark and/or preferential transcription from the paternal allele.
