Mutation signature contributions across race/ethnicity and subtype. a The contribution (proportion) of mutation signatures (Signatures D, E, F, and G are combined into “Other”) within each individual. Individuals are partitioned by race/ethnicity and ordered by APOBEC C > T signature contributions (high to low). The number of individuals representing each cohort is shown. b Mekko plot of the proportional contributions of mutation signatures across IHC subtypes
