Featured Abstract

Association between Inherited Germline Mutations in Cancer Predisposition Genes and Risk of Pancreatic Cancer

Individuals genetically predisposed to pancreatic cancer may benefit from early detection. Genes that predispose to pancreatic cancer and the risks of pancreatic cancer associated with mutations in these genes are not well defined. Mayo Clinic researchers conducted a study to determine whether inherited germline mutations in cancer predisposition genes are associated with increased risks of pancreatic cancer. Individuals were classified based on carrying a deleterious mutation in cancer predisposition genes and having a personal or family history of cancer. Germline mutations in coding regions of 21 cancer predisposition genes were identified by sequencing of products from a custom multiplex polymerase chain reaction-based panel; associations of genes with pancreatic cancer were assessed by comparing frequency of mutations in genes of pancreatic cancer patients with those of reference controls. In this case-control study, mutations in 6 genes associated with pancreatic cancer were found in 5.5% of all pancreatic cancer patients, including 7.9% of patients with a family history of pancreatic cancer and 5.2% of patients without a family history of pancreatic cancer. Further research is needed for replication in other populations. The study was published in the JAMA.
