A high prevalence of genetic polymorphisms in idiopathic and alcohol-associated chronic pancreatitis patients in Ireland
2020
Abstract Background Individual genetic architecture is considered central to susceptibility and progression of disease in chronic pancreatitis. The study aimed to evaluate the presence of common pancreatic gene mutations in a defined cohort of idiopathic and alcohol-induced chronic pancreatitis patients in Ireland. Methods The study comprised patients with idiopathic and alcohol-induced chronic pancreatitis and historic controls. Variants in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, cationic trypsinogen (PRSS1) gene and serine protease inhibitor kazal type-1 (SPINK1) gene, were assessed by Taqman© genotyping assay. Results Of n = 126 patients and n = 167 controls, mutations were detected in 23 (20%) and in 10 (6%) respectively (P Conclusion There was a significant prevalence of chronic pancreatitis-associated gene mutations in this well-phenotyped cohort. In patients with alcohol-related or idiopathic chronic pancreatitis, the possibility of genetic mutations in the SPINK 1 gene should be considered as a contributing aetiology factor.
