Location of the 63 identified DMRs in the genome. Relative location of the identified 37 maternal DMRs and 26 paternal DMRs are shown in the human genome according to the genomic sequence released in 2006 in the UCSC Genome Browser database (hg18). Paternal DMRs are highlighted in blue and maternal DMRs are highlighted in red. Known imprinted genes are boldfaced and underlined. Chromosome 7 contains the highest number of DMRs (nine DMRs), while there are no DMRs identified on chromosomes 13, 21 and Y.
