The majority of tumours were basal-like by PAM50 (75%, 15/20), with HRDetect scores >0.7 found in 80% (12/15) basal-like TNBC and none (0/4) of the non-basal TNBC, with one non-basal BRCA1 mutant ER+ tumour having an HRDscore >0.7 (p = 0.031 Fisher’s exact test, Fig. 5a). The gene discussed is BRCA1; the disease is neoplasm.
