Results from CBCS recapitulated with marginal significance the established relationship between tumor subtype and patient genotype11: that tumors of patients with BRCA1 mutations are more likely to be Basel-like (6 of 16, 37.5%) than were tumors from patients of other genotypes (150 of 855, 17.5%; OR = 2.82, [1.01, 7.88]). The gene discussed is BRCA1; the disease is neoplasm.
