Early Identification of Protein S K196E Mutation in a Patient With Cerebral Venous Thrombosis: A Case Report

Mutation of protein S K196E (PS K196E) is a genetic risk factor for venous thromboembolism; however, there are few reports on cerebral venous thrombosis (CVT) with this mutation. We report a case of CVT that was diagnosed as having PS K196E mutation at the initial thrombotic event.
