Given the different immune profile of the TNBC subtype compared with other BC subtypes, and the associations between BRCA1/2 mutations and TNBC, we selected non-TNBC tissues with BRCA1/2 mutations and non-TNBC BRCA1/2-WT tissues (that is, MUT and WT samples excluding all TNBC subtypes) for comparison. The gene discussed is BRCA1; the disease is breast cancer.
