DNA analyses of the cystic fibrosis transmembrane conductance regulator (CFTR) gene in Japanese patients with idiopathic chronic pancreatitis (ICP) were performed to determine the relationship between the CFTR mutation and ICP. The study included patients with alcoholic pancreatitis (n = 20), patients with ICP (n = 20) and healthy volunteers (controls; n = 110). The poly-T region in intron 8 of the CFTR gene was analysed by direct sequencing. The CFTR coding region was screened using single-strand conformational polymorphism and direct sequencing. In the controls, frequencies of the 5T genotype and 5T allele were 4.5% and 3.6%, respectively. The frequency of the 5T genotype was significantly higher in the ICP group (20%) versus controls, but was not significantly different in alcoholic chronic pancreatitis patients (5%). Thus, the CFTR gene mutation, especially the 5T genotype, appears to have some relationship to ICP prevalence in Japanese patients independent of cystic fibrosis.
