ABSTRACT The set of somatic mutations present in a human tumor is a record of one or more mutational processes, each of which leaves distinct “signature” of mutation types. Mutation types can be classified in various ways, the most straightforward being the base change induced by a single-base substitution (e.g., C>A, T>G, etc.). The advent of high-throughput DNA sequencing has facilitated the comprehensive, genome-wide assessment of mutation types in human tumors. This has spurred the development of methodology to tease […]
