| Outline of Final Research Achievements |
We examined 47 individuals in 22 families of Japanese familial pancreatic cancer kindred to identify susceptible germline variants by whole exome sequencing. Nonsynonymous single nucleotide variants, splice-site variants, insertions, and deletions that were rarely found or not found in the 1000 Genome or the Human Genetic Variation databases were collected. Known susceptible genes and genes identified as candidate pancreatic cancer genes in the mouse sleeping beauty experiment were selected. We found potentially susceptible germline variants in BRCA2, PALB2, PUM1, FARP1, FAM193A, CTNNA1, and MLL5. These germline variants may contribute to susceptibility to familial pancreatic cancer in Japan. We also examined acinar cell carcinoma cases by whole exome and found germline variants in BRCA2 and FAT genes with loss of the wild type allele in cancer tissues. Moreover, we determined clinicopathological and molecular characteristics of familial pancreatic cancer and its associated lesions.
