RAD51D and breast cancer: Among the genes that had no evidence of association with overall breast cancer risk, RAD51D showed some evidence of association with ER-negative disease (OR = 11.26 (CI 95% 2.60–48.68), p-value = 1.19 × 10−3, p-diff = 0.049 for difference with ER-positive disease) (Figure 2, Table 1).
