Xie W et al (2012), showed the presence of a
differentially methylated region upstream of Neurog3 gene. The DMR spans 44 bp
(61,590,706-61,590,749;mm9 build) and contains 9 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.
