- Description
- Understanding of the etiology and risk of pancreatic cancer (PaCa) is still poorly understood. This study evaluated the prevalence of 10 Polish founder mutations in four genes among PaCa patients and assessed their possible association with the risk of disease in Poland. In the study 383 PaCa patients and 4,000 control subjects were genotyped for founder mutations in: BRCA1 (5382insC, 4153delA, C61G), CHEK2 (1100delC, IVS2 + 1G > A, del5395, I157T), NBS1 (657del5) and PALB2 (509-510delGA, 172-175delTTGT). A statistically significant association between the 657del5 mutation and an increased risk of pancreatic cancer was observed for NBS1 gene. The Slavic NBS1 gene mutation (657delACAAA) was detected in 8 of 383 (2.09%) unselected cases compared with 22 of 4,000 (0.55%) controls (OR: 3.80, p = 0.002). The PALB2 509_510delGA and 172-175delTTGT mutations combined were seen in 2 (0.52%) unselected cases of PaCa and in 8 (0.20%) of 4,000 controls (OR: 2.61, p = 0.49). For BRCA1, the three mutations combined were detected in 4 of 383 (1.04%) PaCa patients and in 17 of 4,000 (0.42%) controls (OR: 2.46, p = 0.20). CHEK2 mutations were not associated with the risk of pancreatic cancer (OR: 1.11, p = 0.72). The founder mutation in NBS1 (657del5) was associated with an increased risk of PaCa in heterozygous carriers, indicating that this mutation appears to predispose to cancer of the pancreas. By identifying pancreatic cancer risk groups, founder mutation testing in Poland should be considered for people at risk for PaCa.
