• We compared the frequency of PPM1D mutation in the white blood cells from 1295 ovarian cancer case patients and 834 control subjects. We found a truncating mutation in 20 case patients vs 1 control subject (odds ratio [OR] = 13.07; 95% confidence interval [CI] = 1.75 to 97.55; P < .001). The 12-year mortality of the PPM1D-positive case patients was higher than that of the PPM1D-negative case patients (hazard ratio = 2.02; 95% CI = 1.21 to 3.39; P = .007). Three of the 20 PPM1D carrier case patients had a past history of breast cancer compared with 29 of 1129 noncarriers (OR = 6.69; 95% CI = 1.86 to 24.11; P = .007). The lifetime risks for breast or ovarian cancer among female first-degree relatives of PPM1D mutation carriers were not increased compared with that of case patients without mutations. These observations suggest PPM1D mutations in the mosaic state predispose women to breast and ovarian cancer in the absence of a family history of cancer.
