Table 1 Numbers of C → T and G → A mutations found in CpG dinucleotides and CpHpG trinucleotides in a dataset of 54,625 missense and nonsense mutations in 2,113 different human genes (HGMD) and the numbers of possible C → T and G → A mutations in CpG dinucleotides and CpHpG trinucleotides within the coding regions of the mutated genes.

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
