In this study, we found that BUB1, BUB1B, CCNB1, CDC20, ISG15, KIF11, NCAPG, and TTK were not only significantly expressed in corresponding tumor tissues with BRCA somatic mutations compared with WT BC and normal tissue but also showed significant prognostic value for BC (Figures 6A–I). This evidence concerns the gene NCAPG and breast cancer.
