Schematic model of DNA methylation at the MLH1 CpG island and shore. In PBMCs and normal colorectal tissue (left panel), the MLH1 shore incurs hypomethylation in association with variant SNP genotype of rs1800734. No methylation is present at the CpG island in these DNA sources. In colorectal tumour (right panel), DNA methylation at the CpG shore loses its association with rs1800734 genotype whereas the CpG island incurs hypermethylation in association with variant SNP genotype of rs1800734
