A Case Report of CHEK2 and MUTYH Germline Mutations Associated With Cholangiocarcinoma in a Young Patient

Cholangiocarcinoma (CCA) is a major cause of primary liver carcinoma and has been associated with the penetrance of several germline mutations. We present a 31-year-old female evaluated for left upper quadrant pain and abnormal liver function tests. Ultrasound revealed a nodule in the liver, and bio...

Sumario:Cholangiocarcinoma (CCA) is a major cause of primary liver carcinoma and has been associated with the penetrance of several germline mutations. We present a 31-year-old female evaluated for left upper quadrant pain and abnormal liver function tests. Ultrasound revealed a nodule in the liver, and biopsy showed intrahepatic adenocarcinoma. Germline testing was positive for two mutations: c.1100delC and c.1227_1228dupGG on the CHEK2 gene and the MUTYH gene, respectively. The patient was started on chemotherapy and tolerated it well. We aimed to demonstrate an association between CHEK2 and MUTYH mutations with CCA and highlight the importance of genetic testing for at-risk patients.
