, The patient’s other mutation is F508del. Missense mutation Arginine to Glycine at codon 1283. Predicted by PolyPhen as Probably Damaging; Align GVGD classifies it as C65 (most likely to interfere with function); highly conserved nucleotide and amino acid.
c.3848G>A , p.Arg1283Lys (CFTR1) ? , This mutation in exon 20 of the CFTR gene was caused by a G to A substitution at nucleotide 3980. This change creates a MboII site giving a similar pattern (fragments of almost the same sixe) as G1244E and destroys the same MnII site as W1282X. It was found on a french CF chromosomes bearing haplotype C and appears to be rare: 1 out of 1200 CF chromosomes and was never found on 200 normal chromosomes studied. As the Arginine at this position is not always conserved and as tis change is not severe we are not sure that this substitution is a disease causing mutation. c.3848G>T , p.Arg1283Met (CFTR1) ? , The mutation destroys the same Mnl I restriction site as W1282X and consequently some members of the consortium may have to recharacterize their W1282X mutants if they were originally identififed through this digest. R1283M creates a Fok I site and can also be detected using some ASo's . This mutation is present is present in 3 unrelated patients in our population and thus accounts for 0.8% of our chromosomes. Two of the patients are of Welsh descent and the third is of either English or Welsh descent. All three of the individuals have moderate to severe phenotypes. Since this mutation is not present on 51 normal chromosomes nor on 85 [delta]F508 chromosomes, and since it would cause a non-conservative amino acid substituion, we believe that it is a disease causing mutation. |

Polymorphisms of MRP1 (ABCC1) and related ATP-dependent drug transporters.
Pharmacogenet Genomics. 2005 Aug;15(8):523-33., [PMID:16006996]
Abstract [show]
Genetic variations in drug metabolizing enzymes and targets are established determinants of adverse drug reactions and interactions, but less is known about the role of genetic polymorphisms in membrane transport proteins. MRP1 (ABCC1) is one of 13 polytopic membrane proteins that comprise the 'C' subfamily of the ATP-binding cassette (ABC) superfamily of transport proteins. MRP1 and related ABCC family members, including MRP2, 3, 4 and 5 (ABCC2, 3, 4 and 5), each have a distinctive pattern of tissue expression and substrate specificity. Together, these five transporters play important roles in the disposition and elimination of drugs and other organic anions, and in maintenance of blood-tissue barriers, as confirmed by enhanced chemosensitivity of respective knockout mice. Moreover, Mrp2 (Abcc2) deficient animals display mild conjugated hyperbilirubinemia, corresponding to a human condition known as Dubin-Johnson syndrome (DJS). Naturally occurring mutations in MRP/ABCC-related drug transporters have been reported, some of which are non-synonymous single nucleotide polymorphisms. The consequences of the resulting amino acid changes can sometimes be predicted from in vitro site-directed mutagenesis studies or from knowledge of mutations of analogous (conserved) residues in ABCC proteins that cause DJS, Pseudoxanthoma elasticum (ABCC6), cystic fibrosis (CFTR/ABCC7) or persistent hyperinsulinemic hypoglycemia of infancy (SUR1/ABCC8). Continual updating of databases of sequence variants and haplotype analysis, together with in vitro biochemical validation assays and pharmacological studies in knockout animals, should make it possible to determine how genetic variation in the MRP-related transporters contributes to the range of responses to drugs and chemicals observed in different human populations.

Unilateral renal agenesis associated with congenital bilateral absence of the vas deferens: phenotypic findings and genetic considerations.
Hum Reprod. 2001 Feb;16(2):282-8., [PMID:11157821]
Abstract [show]
An association between congenital bilateral absence of the vas deferens (CBAVD), normal renal anatomy and cystic fibrosis (CF) gene mutations is well established (CF/CBAVD). We postulate that unilateral renal agenesis (URA) and CBAVD (URA/CBAVD) may have a non-CF mutation-mediated genetic basis that leads to abnormal development of the entire mesonephric duct at a very early stage in embryo development (< or =7 weeks). The physical, laboratory and radiographic findings of men with URA/CBAVD (n = 17) and CF/CBAVD (n = 97) were compared; the fertilization and pregnancy rates in the URA/CBAVD population calculated, and the incidence of renal agenesis in immediate family members and offspring of men with URA/CBAVD analysed. No statistical differences could be identified within any of the above comparisons. The fertilization rate for the URA/CBAVD group was 58.2 +/- 26.3%. Eight infants and two fetuses had normal renal anatomy, while one terminated male fetus had bilateral renal and vasal agenesis. Thirty first-order relatives had normal renal units. Anatomical expression of the reproductive ductal derivatives in men with URA/CBAVD and CF/CBAVD was similar, but the phenotypic outcome of the renal portion of the mesonephric duct was different. The potential for transmission of this fatal anomaly reinforces the need for prenatal ultrasounds with all pregnancies involving URA/CBAVD men.

Cystic fibrosis phenotype evaluation and paternity outcome in 50 males with congenital bilateral absence of vas deferens.
Hum Reprod. 2001 Oct;16(10):2093-7., [PMID:11574497]
Abstract [show]
BACKGROUND: Most infertile males with congenital bilateral absence of vas deferens (CBAVD) carry mutations on the cystic fibrosis transmembrane conductance regulator gene and may express mild cystic fibrosis (CF) symptoms. Barriers to paternity for these men can now be overcome by assisted reproduction. Our aims were to investigate the CF-related phenotype and clinical outcome for 50 patients with CBAVD seen at a CF adult centre between 1992 and 1999. METHODS AND RESULTS: The investigation of the patients included screening for 22 CF mutations and identification of the poly-T variant of intron 8, sweat testing, clinical investigation for CF-related extra-genital manifestations, and genetic counselling. CFTR mutations were detected on 56 alleles of the 50 patients. A total of 15 (30%) was compound heterozygote and 26 (52%) heterozygote. In all, 38% of the patients had a positive sweat test. Four patients were diagnosed with typical CF not detected previously. Twenty-one patients became fathers following ICSI (eight cases), artificial insemination by donor or IVF with sperm donor (seven cases) or through adoption (six cases). A mail survey allowed the identification of CF-related clinical symptoms. Information on the occurrence of CF-related symptoms was obtained for 58.5% of patients: in the absence of initial symptoms, no new clinical signs were reported. CONCLUSION: Patients diagnosed with CBAVD need genetic counselling before assisted reproduction. Even when no wish for paternity is expressed, CF gene screening should be associated with at least a sweat test and clinical evaluation because of possible mild forms of CF disease. Medical follow-up did not reveal any new symptoms.

Analysis by mass spectrometry of 100 cystic fibrosis gene mutations in 92 patients with congenital bilateral absence of the vas deferens.
Hum Reprod. 2002 Aug;17(8):2066-72., [PMID:12151438]
Abstract [show]
BACKGROUND: Limited mutation analysis for congenital bilateral absence of the vas deferens (CBAVD) has revealed only a minority of men in whom two distinct mutations were detected. We aimed to determine whether a more extensive mutation analysis would be of benefit in genetic counselling and prenatal diagnosis. METHODS: We studied a cohort of 92 men with CBAVD using mass spectrometry and primer oligonucleotide base extension to analyse an approximately hierarchical set of the most common 100 CF mutations. RESULTS: Analysis of 100 CF mutations identified 33/92 (35.9%) patients with two mutations and 29/92 (31.5%) with one mutation, compound heterozygosity accounting for 94% (31/33) of those with two mutations. This panel detected 12.0% more CBAVD men with at least one mutation and identified a second mutation in >50% of those considered to be heterozygotes under the two routine 25 mutation panel analyses. CONCLUSION: Compound heterozygosity of severe/mild mutations accounted for the vast majority of the CBAVD patients with two mutations, and underscores the value of a more extensive CF mutation panel for men with CBAVD. The CF100 panel enables higher carrier detection rates especially for men with CBAVD, their partners, partners of known CF carriers, and those with 'mild' CF with rarer mutations.

Genotyping microarray for the detection of more than 200 CFTR mutations in ethnically diverse populations.
J Mol Diagn. 2005 Aug;7(3):375-87., [PMID:16049310]
Abstract [show]
Cystic fibrosis (CF), which is due to mutations in the cystic fibrosis transmembrane conductance regulator gene, is a common life-shortening disease. Although CF occurs with the highest incidence in Caucasians, it also occurs in other ethnicities with variable frequency. Recent national guidelines suggest that all couples contemplating pregnancy should be informed of molecular screening for CF carrier status for purposes of genetic counseling. Commercially available CF carrier screening panels offer a limited panel of mutations, however, making them insufficiently sensitive for certain groups within an ethnically diverse population. This discrepancy is even more pronounced when such carrier screening panels are used for diagnostic purposes. By means of arrayed primer extension technology, we have designed a genotyping microarray with 204 probe sites for CF transmembrane conductance regulator gene mutation detection. The arrayed primer extension array, based on a platform technology for disease detection with multiple applications, is a robust, cost-effective, and easily modifiable assay suitable for CF carrier screening and disease detection.

Spectrum of CFTR mutations in cystic fibrosis and in congenital absence of the vas deferens in France.
Hum Mutat. 2000;16(2):143-56., [PMID:10923036]
Abstract [show]
We have collated the results of cystic fibrosis (CF) mutation analysis conducted in 19 laboratories in France. We have analyzed 7, 420 CF alleles, demonstrating a total of 310 different mutations including 24 not reported previously, accounting for 93.56% of CF genes. The most common were F508del (67.18%; range 61-80), G542X (2.86%; range 1-6.7%), N1303K (2.10%; range 0.75-4.6%), and 1717-1G>A (1.31%; range 0-2.8%). Only 11 mutations had relative frequencies >0. 4%, 140 mutations were found on a small number of CF alleles (from 29 to two), and 154 were unique. These data show a clear geographical and/or ethnic variation in the distribution of the most common CF mutations. This spectrum of CF mutations, the largest ever reported in one country, has generated 481 different genotypes. We also investigated a cohort of 800 French men with congenital bilateral absence of the vas deferens (CBAVD) and identified a total of 137 different CFTR mutations. Screening for the most common CF defects in addition to assessment for IVS8-5T allowed us to detect two mutations in 47.63% and one in 24.63% of CBAVD patients. In a subset of 327 CBAVD men who were more extensively investigated through the scanning of coding/flanking sequences, 516 of 654 (78. 90%) alleles were identified, with 15.90% and 70.95% of patients carrying one or two mutations, respectively, and only 13.15% without any detectable CFTR abnormality. The distribution of genotypes, classified according to the expected effect of their mutations on CFTR protein, clearly differed between both populations. CF patients had two severe mutations (87.77%) or one severe and one mild/variable mutation (11.33%), whereas CBAVD men had either a severe and a mild/variable (87.89%) or two mild/variable (11.57%) mutations.

Independent origins of cystic fibrosis mutations R334W, R347P, R1162X, and 3849 + 10kbC-->T provide evidence of mutation recurrence in the CFTR gene.
Am J Hum Genet. 1994 Nov;55(5):890-8., [PMID:7526685]
Abstract [show]
Microsatellite analysis of chromosomes carrying particular cystic fibrosis mutations has shown different haplotypes in four cases: R334W, R347P, R1162X, and 3849 + 10kbC-->T. To investigate the possibility of recurrence of these mutations, analysis of intra- and extragenic markers flanking these mutations has been performed. Recurrence is the most plausible explanation, as it becomes necessary to postulate either double recombinations or single recombinations in conjunction with slippage at one or more microsatellite loci, to explain the combination of mutations and microsatellites if the mutations arose only once. Also in support of recurrence, mutations R334W, R347P, R1162X, and 3849 + 10kbC-->T involve CpG dinucleotides, which are known to have an increased mutation rate. Although only 15.7% of point mutations in the coding sequence of CFTR have occurred at CpG dinucleotides, approximately half of these CpG sites have mutated at least once. Specific nucleotide positions of the coding region of CFTR, distinct from CpG sequences, also seem to have a higher mutation rate, and so it is possible that the mutations observed are recurrent. G-->A transitions are the most common change found in those positions involved in more than one mutational event in CFTR.

Mutation analysis in 600 French cystic fibrosis patients.
J Med Genet. 1994 Jul;31(7):541-4., [PMID:7525963]
Abstract [show]
The cystic fibrosis transmembrane conductance regulator (CFTR) gene of 600 unrelated cystic fibrosis (CF) patients living in France (excluding Brittany) was screened for 105 different mutations. This analysis resulted in the identification of 86% of the CF alleles and complete genotyping of 76% of the patients. The most frequent mutations in this population after delta F508 (69% of the CF chromosomes) are G542X (3.3%), N1303K (1.8%), W1282X (1.5%), 1717-1G-->A (1.3%), 2184delA + 2183 A-->G (0.9%), and R553X (0.8%).

[Male infertility caused by bilateral agenesis of the vas deferens: a new clinical form of cystic fibrosis?].
Rev Med Interne. 1997;18(2):114-8., [PMID:9092029]
Abstract [show]
Congenital bilateral absence of vas deferens causes male excretory infertility and represents 1 to 2% of male infertility. Because of a genotypic similarity with cystic fibrosis, the possible in vitro fertilization with epididymal sperm requires careful genetic counselling. We studied genotype, sweat chloride concentration, respiratory function tests, sinus abnormalities, pancreatic and hepatic functions in 22 subjects with congenital bilateral absence of vas deferens. Among them, four were compound heterozygotus, all of them with the R117H mutation. Ten had a positive sweat test, one of them also being compound heterozygotus. Congenital bilateral absence of vas deferens and double mutation or positive sweat test led to high probable cystic fibrosis diagnosis in 13 subjects. Six subjects were heterozygotus for one cystic fibrosis mutation, criterium which is not sufficient for cystic fibrosis diagnosis; five of them had sinus abnormalities, present in 11 of the 22 subjects. Only three patients had no mutation nor sweat chloride abnormalities. This work confirms the high frequency of cystic fibrosis mutations in males with congenital bilateral absence of vas deferens, with a higher frequency of positive sweat test than in other publications, and a high frequency of sinus abnormalities. This monosymptomatic phenotype of cystic fibrosis suggests new hypotheses for a relationship between genotype and phenotype.
