Extended Data Fig. 9: Major signature contributions from urothelial cancer patients’ tumors measured through whole-genome sequencing.

Top: total mutation counts per sequenced tumor. Bottom: signature contributions. Trinucleotide frequencies were fit to the entire COSMIC database (version v.3.3). When a patient had two or more tumors (B01, B04, B15, B16, B17, B18, B19), we measured signature contributions of mutations that were present in two or more tumors and thereby likely reflect mutations that arise earlier in tumor evolution.
