	1	Association of rare SPINK1 gene mutation with another base substitution in chronic pancreatitis patients显示文摘AIM: To verify and expand the known spectrum of serine protease inhibitor Kazal type 1 (SPINK1) gene mutations in chronic pancreatitis. METHODS: DNA extracted from 172 chronic pancreatitis patients was assayed for SPINK1 gene mutations by PCR and DNA sequencing. A control cohort of 90 unrelated healthy individuals was analysed by the same methods for presence of common populational polymorphisms, and frequency of five-loci haplotypes was calculated. Linkages of gene aberrations in single SPINK1 gene copies were analysed by long-distance PCR followed by allele-specifi c PCR and DNA sequencing. RESULTS: The most frequent SPINK1 gene mutation N34S was found at a frequency of 6%. Furthermore, we detected the heterozygous intervening sequence (IVS) 3 + 2 T > C mutated gene in 2 German patients and 1 Macedonian chronic pancreatitis patient. In all three SPINK1 gene copies an additional rare base substitution was found: 5’untranslated region (UTR)-215 G > A. Poly-morphism analysis revealed that all three affected genes carried the same fi ve-loci haplotype. DNA sequencing of another chronic pancreatitis-related gene PRSS1 (cationic trypsinogen) did not reveal any mutations in these 3 pa-tients.CONCLUSION: We found in 3 (2%) of 172 chronic pancreatitis patients an IVS3 + 2 T > C SPINK1 gene mutation and a base substitution 5’UTR-215 G > A inthe same gene copy. Most probably the 5’UTR-215 G >A represents a rare polymorphism and not a mutationas previously concluded. Haplotype analysis suggests acommon origin of the IVS3 + 2 T > C mutation in thesepatients.
