Determination of the relative contribution of three genes-the cystic fibrosis transmembrane conductance regulator gene, the cationic trypsinogen gene, and the pancreatic secretory trypsin inhibitor gene-to the etiology of idiopathic chronic pancreatitis.
Eur J Hum Genet. 2002 Feb;10(2):100-6., [PMID:11938439]

Abstract [show]
In the last 5 years, mutations in three genes, the cystic fibrosis transmembrane conductance regulator (CFTR) gene, the cationic trypsinogen (PRSS1) gene, and the pancreatic secretory trypsin inhibitor (PSTI) gene, have been found to be associated with chronic pancreatitis (CP). In this study, using established mutation screening methods, we systematically analysed the entire coding sequences and all exon/intron junctions of the three genes in 39 patients with idiopathic CP (ICP), with a view to evaluating the relative contribution of each gene to the aetiology of the disease. Our results demonstrate that, firstly, 'gain-of-function' mutations in the PRSS1 gene may occasionally be found in an obvious ICP subject. Secondly, presumably 'loss-of-function' mutations in the PSTI gene appear to be frequent, with a detection rate of at least 10% in ICP and, finally, abnormal CFTR alleles are common: at least 20% of patients carried one of the most common CFTR mutations, and about 10% of patients were compound heterozygotes, having at least one 'mild' allele. Thus, in total, about 30% of ICP patients carried at least one abnormal allele in one of the three genes, and this is the most conservative estimate. Moreover, a trans-heterozygous state with sequence variations in the PSTI/CFTR genes was found in three patients. However, an association between the 5T allele in intron 8 of the CFTR gene and ICP remains unproven.

85 Firstly, we found a total of 10 additional alleles (R352Q, P5L, c.4575+2G4A, V562I, IVS3-6T4C, E217G/A1136T, IVS18-20T4C, and L967S; Table 1) that would have been missed by the conventional genotyping method. Login to comment
87 For example, R352Q, P5L, and A1136T occur in strictly conserved residues (refer to Figure 2 in Chen et al33 ). Login to comment
88 In particular, R352Q is within the stringently conserved motif T351-R352- Q353, which is immediately downstream of TM6 and has been suggested to loop back into the chloride channel, narrowing the lumen and thereby forming both the major resistance to current flow and the anion selectivity filter;34 A1136T is within TM12; c.4575+2G4A, occurring just two nucleotides downstream of the translation stop codon, may affect the interplay between splicing and polyadenylation or alter the mRNA stability; Q1476X is a nonsense mutation.

Reduced CFTR function and the pathobiology of idiopathic pancreatitis.
J Clin Gastroenterol. 2005 Apr;39(4 Suppl 2):S70-7., [PMID:15758663]

Abstract [show]
Idiopathic chronic pancreatitis (ICP) is the leading cause of chronic pancreatitis in children and nonalcoholic adults. The risk of developing ICP is increased in individuals who have mutations of the cystic fibrosis gene (CFTR) and of a trypsin inhibitor gene (PSTI). In studies from the United States and France, the risk of ICP is increased about 40-fold by having two abnormal copies of the CFTR gene, about 14-fold by having the N34S PSTI mutation, and about 500-fold by having both. When ICP patients have two abnormal copies of the CFTR gene, there is also evidence of reduced residual CFTR protein function in extrapancreatic tissues based on clinical findings and nasal ion transport responses. Thus, pancreatitis risk is highest in individuals who have abnormalities in both the pancreatic ducts (CFTR) and acini (PSTI). These findings indicate that PSTI is a modifier gene for CFTR-related ICP and have implications for the diagnosis and pathogenesis of pancreatitis.

Abstract [show]
BACKGROUND: Genetic testing of the cystic fibrosis transmembrane conductance (CFTR) gene is currently performed in patients with congenital bilateral absence of vas deferens (CBAVD). This study was conducted to investigate the role of mutations in the CFTR gene in CBAVD-dependent male infertility. METHODS: 73 Chinese patients diagnosed with CBAVD were studied. The entire coding regions and splice sites of 27 exons of the CFTR gene were sequenced in 146 chromosomes from the 73 CBAVD patients. Screening was carried out using PCR, gel electrophoresis and DNA sequencing to identify novel variants of the entire coding regions and boundaries of the 27 exons. RESULTS: Five novel nonsynonymous mutations, three novel splice site mutations and one deletion were identified by sequencing. Apart from the novel variants, we also found 19 previously reported mutations and polymorphism sites. Thirty-four patients (46.57%) had the 5T variant (6 homozygous and 28 heterozygous) and in two of them it was not associated with any detectable mutation of the CFTR gene. All potential pathogenic mutations are not contained in the 1000 Genome Project database. In total, the present study identified 30 potential pathogenic variations in the CFTR gene, 9 of which had not previously been described. CONCLUSIONS: Most patients with CBAVD have mutations in the CFTR gene. A mild genotype with one or two mild or variable mutations was observed in all the patients. These findings improve our understanding of the distribution of CFTR alleles in CBAVD patients and will facilitate the development of more sensitive CFTR mutation screening.

Abstract [show]
Preimplantation genetic diagnosis (PGD) for inherited disorders is presently applied for more than 300 different conditions. The most frequent PGD indication is cystic fibrosis (CF), the largest series of which is reviewed here, totalling 404 PGD cycles. This involved testing for 52 different CFTR mutations with almost half of the cases (195/404 cycles) performed for DeltaF508 mutation, one-quarter (103/404 cycles) for six other frequent mutations and only a few for the remaining 45 CFTR mutations. There were 44 PGD cycles performed for 25 CF-affected homozygous or double-heterozygous CF patients (18 male and seven female partners), which involved testing simultaneously for three mutations, resulting in birth of 13 healthy CF-free children and no misdiagnosis. PGD was also performed for six couples at a combined risk of producing offspring with CF and another genetic disorder. Concomitant testing for CFTR and other mutations resulted in birth of six healthy children, free of both CF and another genetic disorder in all but one cycle. A total of 96 PGD cycles for CF were performed with simultaneous aneuploidy testing, including microarray-based 24-chromosome analysis, as a comprehensive PGD for two or more conditions in the same biopsy material.
