Exome data of cancerous tumors in biliary tract cancers

We collected data from 13 patients with tumors in the biliary tract cancers invading the bile duct and subsequently underwent surgical resection: 7 cholangiocarcinomas, 1 gallbladder carcinoma, 3 ampullary carcinomas, 1 pancreatic cancer, and 1 intraductal papillary mucinous carcinoma. Whole-exome sequencing-based extracted DNA from resected samples revealed pathogenic alterations of TP53, ABCA8, BRCA2, FGFR2, APC, SMAD4 and NRAS.
