There are clear examples with germline mutations in genes like adenomatous polyposis coli (APC), cadherin 1 (CDH1), BRCA1, von Hippel-Lindau tumor suppressor (VHL), and ataxia telangiectasia mutated (ATM) which are causative for the development of cancer in specific types of tissue (Schneider et al., 2017). Here, CDH1 is linked to cancer.
