Somatic mutation landscape in pre-diagnosis tissues versus healthy controls. A Comparison of the number of mutations per sample categorized by source (germline, somatic, or combined) between the two groups, across four quartiles. B Oncoplots of genes that are most frequently affected by somatic mutations in the two different cohorts. Percent numbers indicate the fraction of cases affected. Asterisks indicate genes with significantly different mutation frequencies between the groups
