Among patients with breast tumors, BARD1 mutations were correlated with solid tubular histology, nuclear grade 3, and triple-negative subtype (OR = 6.7, 10.0, and 6.0, respectively; p = 0.01, p < 0.01, and p = 0.02, Fisher exact tests; Table 4)13. This evidence concerns the gene BARD1 and breast neoplasm.
