Activating mutations in the KRAS gene are present in more than 80% of pancreatic cancers and more than 30% of colorectal cancers (Timar and Kashofer, 2020) and have been shown to be significantly associated with the poor prognosis of many cancers, such as pancreatic cancer (Buscail et al., 2020) and non-small cell lung cancer (Cai et al., 2020). Here, KRAS is linked to familial pancreatic carcinoma.
