Xie W et al (2012), showed the presence of a
differentially methylated region in the intragenic region of Casc1. The DMR spans 124 bp
(14,5136,212-14,5136,335;mm9 build) and contains 7 CpG dinucleotides which are maternally
methylated. Additionally, allele specific enrichment of the active histone mark, H3K4me3 was
observed on the paternal allele.
