Basing on data already available, we decided to start in our institution a specific genetic protocol focused on biliary tract cancer patients, which includes genetic counseling and, if indicated, germline test. The inclusion criteria are: 1) Patient with personal history of oncologic disease other than BTC, 2) Patient with familiar history of oncologic disease (considering relatives of first and second grade), 3) Patient with ≤ 50 years old, 4) Patient presenting a somatic mutation in genes involved in DNA damage repair pathways and mismatch repair. The aim of the presented protocol is to identify germline pathogenic variants with prophylactic and therapeutic impact, and to collect and integrate a significant amount of clinical, familial, somatic, and genetic data.
