ATM (OR [95% CI] = 1.82 [1.20, 2.75], p = 4.64 × 10−3) was positively associated in our prostate cancer-specific case-case analysis, and the two remaining genes were positively associated in our breast cancer-specific case-case analysis: BRCA1 (OR [95% CI] = 2.38 [1.07, 5.30], p = 0.0340) and BRCA2 (OR [95% CI] = 1.97 [1.22, 3.18], p = 5.50 × 10−3). This evidence concerns the gene ATM and prostate cancer.
