William Foulkes and colleagues identify germline inactivating mutations in familial cases of small cell carcinoma of the ovary, hypercalcemic type (SCCOHT). Through additional analysis of non-familial tumors, the authors find that nearly 100% of tumors carry SMARCA4 mutations and 38 of 40 lack protein expression, implicating SMARCA4 loss as the major cause of SCCOHT.
