Twenty invasive breast tumours and one HGSOC from 21 cases were analysed using whole-exome sequencing (n = 5), Sanger sequencing (n = 2), and/or a targeted sequencing gene panel that included all exons and intron boundaries of RAD51C and other common BC somatically mutated genes (n = 14) (Table 2). This evidence concerns the gene RAD51C and breast cancer.
