['BRCA2 mutations are the well-known cause of inherited susceptibility to pancreatic cancer. However, the true association of BRCA2 mutations with pancreatic cancer may vary among different ethnic groups. As such, we aimed to determine the role of BRCA2 mutations as a risk factor for sporadic and familial pancreatic cancer in Korean patients.', 'Between January 1998 to October 2002, 110 patients with pancreatic ductal adenocarcinoma gave informed consent for pedigree cancer survey. Analysis of BRCA2 mutations was done in 60 of those patients, all of whom agreed to genetic test. BRCA 2 mutation was analyzed by denaturing high-performance liquid chromatography and direct sequencing.', 'Among the 110 patients, 8 cases (7.2%) were confirmed as familial pancreatic cancer. There were no pathogenic BRCA2 truncation mutations in 60 patients with BRCA2 mutation analysis. However, 2 single polymorphic amino acid changes, C1342A(H372N), A3199G(N991D), a silent polymorphism A7470G(S2414S), a splice site mutation intron 16:-14(T to C) polymorphism, and an intron 16:-12 (T to C) unclassified variant were detected in both 9 of 53 sporadic and 1 of 7 familial pancreatic cancer patients.'] Does bRCA2 mutations as a universal risk factor for pancreatic cancer have a limited role in Korean ethnic group?
