A role for cis -regulatory elements in methylation fidelity was also demonstrated by highly significant (p<2.2×10 −5 ) enrichment of transcription factor binding sites in CGI probe loci showing heritably high (118 elements) and low (47 elements) methylation, and also in loci demonstrating stochastic hyper-(30 elements) and hypo-(31 elements) methylation.
