Our study is part of a multicenter, multidisciplinary Pancreatic Cancer Genetic Epidemiology (PACGENE) consortium to identify susceptibility genes in high risk FPC pedigrees using cutting-edge genetic analysis methods.
1. To identify high risk pedigrees for genetic linkage analysis utilizing established pancreatic cancer family research resources. We will recruit and screen new pancreatic cancer patients over 5 years to accrue biospecimens, tumor tissues, and risk factor data (including family history) from available relevant family members of familial pancreatic cancer (FPC) pedigrees suitable for genetic linkage studies (those with 3 or more persons affected with pancreatic cancer and those providing expected lod score of 0.3 or higher.
2. To genotype informative individuals in high-risk FPC pedigrees with 400 evenly spaced markers (~ 10 centimorgan intervals) throughout the genome. We will also perform genotyping with genome-wide microsatellite markers.
3. To map a pancreatic cancer susceptibility gene(s) by genetic linkage analysis of the high-risk FPC pedigrees. We propose to use conventional parametric linkage strategies, but will also implement the latest methods that incorporate environmental covariates in the analysis. |
