For case-control comparisons, odds ratios (with 95% confidence intervals) for breast cancer of all subtypes combined were 26.7 (3.59, 189.1) for BRCA1; 8.8 (3.44, 22.48) for BRCA2; and 9.0 (2.06, 39.60) for PALB2. Case-control odds ratios for TNBC were 55.0 (7.01, 431.4) for BRCA1; 12.1 (4.18, 35.12) for BRCA2; and 10.8 (1.97, 59.11) for PALB2 (Table 2). This evidence concerns the gene PALB2 and breast carcinoma.
