Figure 5: The CTCF locus and its distally associated CpG sites.

(a) UCSC browser illustration of the gene structure and location of SNPs associated with distal CpG sites, and boxplot representation of the association in cis between CTCF expression and SNP genotypes. (b–h) Distally associated CpG sites, their gene annotations and boxplot representations of SNP–CpG associations. The Transcription Factor ChIP-seq from ENCODE tracks are displayed in the UCSC browser illustrations to indicate CTCF-binding sites.
