However, clinical application of this observation is hampered by the lack of knowledge regarding subpopulations at risk for SNs who could potentially benefit from genetic screening.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>PATIENTS AND METHODS<\/jats:title>\n            <jats:p>Whole-exome sequencing was performed using germline DNA from 499 survivors with SNs (cases) and 625 survivors without (matched controls) in a Children's Oncology Group study. Using conditional logistic regression, we estimated demographic\/clinical\/therapeutic characteristics and P\/LP mutations associated with SN risk. We then randomly partitioned the case-control data set using a 60\/40 split to create training and test data, respectively, and developed a clinical risk classifier. Model performance and its improvement with addition of P\/LP mutation status was evaluated on the test data using the area under the receiver operating curve (AUC).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>RESULTS<\/jats:title>\n            <jats:p>\n              We found a 4.26-fold higher odds of SNs among P\/LP mutation carriers (95% CI, 2.36 to 7.69). The clinical risk classifier (including sex, primary cancer type and year of diagnosis, exposure to radiation and platinum compounds, and length of follow-up) showed a significant performance improvement with the addition of P\/LP mutation status, and P\/LP \u00d7 platinum and P\/LP \u00d7 radiation interactions (AUC increased from 0.79 to 0.82,\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              = .014).
