Fisher exact tests with just the 539 breast cancer patients (excluding 29 ovarian cancer patients) yielded almost similar results, except for ATM, which was no longer significant (OR = 11.3, 10.8, 3.8, and 2.4, respectively; p < 0.01, p < 0.01, p = 0.03, and p = 0.07, respectively). This evidence concerns the gene ATM and breast cancer.
