Similarly, the findings for BRCA2 are consistent with those from a previous study of 157 BRCA2 mutation carriers and 314 mutation-negative familial breast cancer cases, which indicated that BRCA2-associated tumors were more likely to be ER-positive than were control tumors, when accounting for grade (OR, 2.09; 95% CI, 1.21 to 3.63; P =0.008) [13]. The gene discussed is BRCA2; the disease is breast cancer.
