Horizontal stacked bar chart showing normalized somatic mutation allele frequencies detected in tumour tissue samples by whole exome sequencing. The mutation with highest tumour allele frequency in a sample is scaled to 100% and the remaining mutations are scaled accordingly. The chart compares the most prominent tumour mutations between samples, irrespective of the tumour cell content in a tissue sample. P marks genes that were covered in plasma cfDNA pan-cancer sequencing
