Sets of significantly methylated gene-associated features compared among tissues determined by the RPKM method. Gene counts per tissue are shown on the diagonal as: number with significantly methylated promoter/number with significantly methylated gene body. Proportions of these sets shared by pairs of tissues is shown, with promoter commonalities above the diagonal and gene body commonalities below the diagonal.
