Principal component analysis (PCA) showing genome-wide DNA methylation similarities between individual tumour, based on 77,113 variably methylated (VM)-CpG probes. Tumour samples of different CRC subgroups are shown in different colours. The MLH1-VUS group includes CRCs from 3 MLH1 germline VUS carriers (two MLH1: c.-11C > T and one MLH1: c.-[28A > G; 7C > T] carriers)
