This gene list was then used to interrogate a TNBC microarray data set enriched for BRCA1 mutations [27] in order to identify a molecular subgroup of breast cancers enriched for this biology and labelled as BRCA1-/NFκB+ (“NFκB on”) and all other tumours labelled as non-BRCA1-/NFκB+ (“NFκB off”). This evidence concerns the gene NFKB1 and neoplasm.
