Mutational Signature Contribution of Matched Primary and Recurrent Breast Tumors

Mutational signature contribution table reports COSMIC mutational signatures (v2; https://cancer.sanger.ac.uk/signatures/signatures_v2/) for matched primary and locally recurrent tumors (n = 27 + 27). "SUBSTITUTION.TABLE" contains the number of nucleotide substitutions (type by sample). "MUT.SIG.contribution" reorts the fractional contribution of all 30 COSMIC signatures in each samples. "MUT.SIG.contrib.DELTA" reports pair-wise contribution difference (DELTA = contribution.recurrence - contribution.primary) for paired samples. This dataset was used for Figure 2 in the following manuscript: "Proteogenomics decodes the evolution of human ipsilateral breast cancer".
