Abstract:
CpG densities and sequence motifs that are characteristic of regions of DNA associated with epimutations and control of epimutations are provided. Such regions include, within approximately 400 (or fewer) base pairs, at least one, usually two, and preferably all three of the following features: i) a CpG density of 15% or less; ii) the presence of the sequence motif ATTTGTTTTTTCTTTTnT (SEQ ID NO: 1) where n is A, T, C or G, and statistically relevant variants thereof; and iii) the presence of the sequence motif GGGGGnGGGG (SEQ ID NO: 2), where n is A, T, C or G, and statistically relevant variants thereof.
