Table 2 Numbers of C → T and G → A mutations found in CpG dinucleotides and CpHpG trinucleotides in a dataset of 1,766 regulatory mutations of 191 gene promoters (HGMD) and the numbers of possible C → T and G → A mutations in CpG dinucleotides and CpHpG trinucleotides.

From: Methylation-mediated deamination of 5-methylcytosine appears to give rise to mutations causing human inherited disease in CpNpG trinucleotides, as well as in CpG dinucleotides
