GNAS and ovarian endometrioid carcinoma: Among the 19 mutations discovered, two identified in endometrioid ovarian carcinomas were previously unreported (Table S1): p.P110H in KRAS and p.C805T in GNAS. Both missense mutations were evaluated as “damaging”, “probably damaging”, “deleterious”, “disease-causing” in SIFT, Polyphen-2, Provean, and MutationTaster, respectively, whereas only p.Pro110His was predicted to potentially affect splicing by HSF.
