In addition, we sequenced whole genomes from 14 additional breast tumors and matched normal samples [24] from patients carrying germline BRCA1/2 mutations, resulting in a dataset of 81 tumor genomes: 27 with germline BRCA1 mutations, 19 with BRCA2 mutations (17 germline and 2 somatic), and 35 sporadic breast tumors without BRCA inactivation, of which 19 were triple-negative and 16 were ER+. Here, BRCA1 is linked to breast neoplasm.
