A multi-center study by Thompson et al. showed that the relative risk of pancreatic cancer in patients with a BRCA1 mutation is 2.26 (95% CI: 1.26–4.06), and another study by Easton et al. showed that the relative risk of pancreatic cancer in patients with a BRCA2 mutation is 3.51 (95% CI: 1.87–6.58) [32,33]. The gene discussed is BRCA1; the disease is familial pancreatic carcinoma.
