Figure 3. Somatic mutation patterns of all 47 epigenetic key genes included in the Comprehensive Cancer Panel.

The codes for mutation classification are 0 (white), not mutant; 1 (light red), one or more mutations (truncating or non-truncating) with variant allele frequency < 25 % in tumor tissue; 2 (medium red), one or more non-truncating mutations with variant allele frequency ≥ 25 % in tumor tissue; 3 (dark red), one or more truncating mutations with variant allele frequency ≥ 25 % in tumor tissue.
