“…The inherited basis of B10-20% of familial pancreatic cancers has been identified and is reflected largely in germline mutations in the BRCA2 gene (Goggins et al, 1996;Ozcelik et al, 1997;Hahn et al, 2003) (The Breast Cancer Linkage Consortium, 1999;Murphy et al, 2002). Germline mutations in the p16 (Goldstein et al, 1995;Lynch et al, 2000;Vasen et al, 2000;Bartsch et al, 2002), FANCC (van der Heijden et al, 2003;Rogers et al, 2004), FANCG (van der Heijden et al, 2003;Rogers et al, 2004), PRSS1 (Lowenfels et al, 1993(Lowenfels et al, , 1997, STK11 (Giardiello et al, 2000;Lim et al, 2004), and hMLH1 (Yamamoto et al, 2001) genes are infrequent causes of familial pancreatic cancer and are associated with a number of cancer syndromes, including familial multiple mole melanoma (FAMMM), hereditary pancreatitis, hereditary nonpolyposis colon cancer, and Peutz-Jeghers syndrome. In addition, germline BRCA2 mutations are observed in B5% of patients with apparently sporadic pancreatic cancer, that is, patients who do not appear to have an inherited predisposition to pancreatic or breast/ovarian cancer (Goggins et al, 1996;Ozcelik et al, 1997;The Breast Cancer Linkage Consortium, 1999;Figer et al, 2001).…”
