Table 3 Annotation of CpG sites and differential methylated regions (DMRs) in the pairwise comparison

From: Genome-wide DNA methylation analysis in Chinese Chenghua and Yorkshire pigs

Genetic features Number Annotated with genea Annotated within CpGb
Promoter Exon Intron Intergenic CpG island CpG shore Other regions
CpG sites 2,416,211 28.31% 15.08% 36.01% 20.60% 48.93% 18.96% 32.11
DMRs 722 3.32% 12.33% 50.69% 33.66% 12.19% 16.48% 71.33%
  1. aAnnotated with gene, the percentage of CpG sites or differential methylated regions that overlap with gene promoter, exon, intron, or intergenic; bAnnotated within CpG, the percentage of CpG sites or differential methylated regions that overlap with CpG island, CpG shore or other regions
