18 CFTR gene studies were pursued using a DGGE scanning strategy,8 9 and the maternal CFTR allele was found to carry three missense mutations, D443Y (1459G>T, exon 9), G576A (1859G>C, exon 12), and R668C (2134C>T exon 13), which have each previously been reported in males with CBAVD.10-12 On further analysis, the complex mutated maternal allele was found in the younger boy.

39 D443Y, G576A, and R668C have been observed independently or in pairs, in patients with a CF related syndrome for whom the whole CFTR coding sequence has been analysed: D443Y, G576A, R668C, D443Y-G576A, D443Y-R668C in CBAVD patients10-12 and G576A-R668C in a patient with disseminated bronchiectasis, but with no other CF causing mutation found in trans.15 To our knowledge, the D443Y mutation was only observed in CBAVD patients.11 12 The G576A and R668C variations have both initially been described as polymorphisms since they were found on the non-CF chromosome of the mother of a CF child.8 However, they were later considered as putative mild mutations associated with a CBAVD phenotype when combined in trans with F508.16 17 These genotypes may possibly not be disease causing in women.

48 It is thus possible that, in our family, the D443Y variation worsens a very mild deleterious eVect of the G576A-R668C allele, or vice versa, accounting for the abnormal sweat test and, perhaps, the respiratory infections in the younger brother. Login to comment

50 CFTR mutations were detected in 387 out of 444 alleles (87.2%), most of them being previously described in patients with CF of varying severity, CBAVD or other CFTR diseases: 45% of identified alleles consisted of severe CF mutations (e.g. F508del, W1282X, 2183AA.G); 13.8% of mild or variable CF mutations (e.g. L206W, 3272-26A.G, R117H, D1152H); 36.7% of mild CFTR defects which are currently not considered CF-causing (e.g. IVS8(T)5, Q1352H, the complex alleles [D443Y;G576A;R668C] and [R74W;D1270N]) and 4.5% of rare missense mutations whose effect is difficult to predict (e.g. A959V, G1069R, V1153E).

142 In fact, they occur in highly conserved regions of the CFTR protein, which share 100% amino acid sequence homology between species48 and affect the NBD1, NBD2, and transmembrane regions of the protein, which are known to regulate chloride conductance and permeability.49-51 P439S was previously reported in a child with CF with pancreatic insufficiency and mild lung disease, in association with the P439S/R688C genotype.52 The E1401K mutation occurs at a position in which other mutations, E1401X and E1401A, have been described in patients with CF with pancreatic insufficiency.8 Some difficulties in defining CF or CAVD-causing mutations were observed with some missense mutations.6,27 G576A and R668C have been found independently, in pairs, or combined with the D443Y mutation on the same chromosome in patients withaCF-relatedsyndrome.Inaccordancewithpreviousstudies, we expected that G576A and R668C were located in cis in two patients and combined with D443Y in the same chromosome in two patients.6,9,12 Although initially described as polymorphisms,27 they were later considered mild mutations associated with the CBAVD phenotype when combined in trans with the severedeltaF508mutation.53 However,ourpresentresultssuggest they might also cause the CAVD phenotype when associated with other mild CFTR mutations, because three of four patients carry- ingthesecomplexallelesharboredamildorverymildmutationin the other chromosome (D443Y-G576A-R668C/3272-26A¡G, Table 5 Comparative analysis of CFTR mutation allelic frequencies (%) in patients with congenital absence of the vas deferens Countries Patients T5 allele DeltaF508 R334W R117H References Argentina 36 NA 20.8 NA 5.6 43 Austria 22 NA 13.6 NA 9.1 44 Italy 12 8.3 29.2 NA 4.2 39 The Netherlands 21 9.5 19.0 NA 21.4 38 Germany 106 12.3 26.4 0.5 11.3 30 Greece 14 14.3 14.3 NA NA 32 France 800 16.3 21.8 NA 4.4 6 United States 92 17.9 21.2 NA 2.2 41 Canada 74 18.2 16.9 1.4 6.1 5 Turkey 51 19.6 2.9 NA NA 35 Brazil 17 20.6 11.7 NA 2.9 34 Spain 134 20.9 16.0 0.4 3.0 33 Iran 113 25.7 12.4 0.9 3.5 37 Egypt 16 43.7 6.2 NA NA 40 Taiwan 27 44.4 NA NA NA 42 Portugal 45 31.1 23.3 6.7 4.4 13, 36, PS NA, not available; PS, present study.

113 The most frequent phenotype associated with combinations of p.Asp443Tyr, p.Gly576Ala, and p.Arg668Cys was CBAVD. Login to comment
117 Outcome was known for seven out of nine cases: (1) one baby, with the triple mutant p.[Asp443Tyr;Gly576Ala;Arg668Cys], was considered possibly affected with mild CF or CFTR-RD at the time of analysis. Login to comment
120 Of the 37 healthy individuals, seven had a severe CF mutation in trans; one carried the triple mutant p.[Asp443Tyr;Gly576Ala;Arg668Cys]; five carried the double mutant p.[Gly576Ala;Arg668Cys]; and one carried p.Arg668Cys in isolation. Login to comment
121 These observations in patients carrying varied combinations of p.Arg668Cys, p.Gly576Ala, p.Asp443Tyr in trans with a classical CF mutation argue against as considering them as CF defects, but as CFTR-RD-associated mutations. Login to comment
122 Epidemiological Data from the French General Population Of the 1,423 healthy individuals screened, 26 were heterozygous for p.[Gly576Ala;Arg668Cys] (allelic frequency 0.91%, 95% CI 0.60-1.33%); four for p.[Asp443Tyr;Gly576Ala;Arg668Cys] (allelic frequency 0.14%, 95% CI 0.04-0.36%); two for p.Arg668Cys; two for p.Gly576Ala (allelic frequency for each 0.07%, 95% CI 0.0080.25%); and one for p.[Ser519Gly;Gly576Ala;Arg668Cys] (allelic frequency 0.04%, 95% CI 0.0009-0.20%).

125 Processing of CFTR Mutants To evaluate the contribution of each mutation to the phenotype, we first studied the maturation of CFTR in HeLa cells that had been transiently transfected with cDNA encoding the WT and mutated CFTR proteins p.Gly149Arg, p.Asp443Tyr, p.Gly576Ala, and p.Arg668Cys in different combinations.

132 A: Western blot analysis of the CFTR expression: 1, WT; 2, p.Gly576Ala; 3, p.Arg668Cys; 4, p.[Gly576Arg;Arg668Cys]; 5, p.[Asp443Tyr;Gly576Ala;Arg668Cys]; 6, pTracer; 7, p.Asp443Tyr. Login to comment
141 Lower amounts of mature p.Asp443Tyr and p.[Asp443Tyr;Gly576Ala;Arg668Cys] proteins were detected, with a decrease in proportion of band C (ratio band C/(band B + band C): 56.9% vs. 83.5 for the WT (Fig. 2A). Login to comment
146 As shown in Figure 3, p.Gly576Ala, p.Arg668Cys, p.Asp443Tyr, p.[Gly576Ala;Arg668Cys], and p.[Asp443Tyr;Gly576Ala;Arg668Cys] were targeted to the plasma membrane (Figs. 3B-F). Login to comment

148 Thus, p.Asp443Tyr seemed to be more perinuclear than p.[Asp443Tyr;Gly576Ala;Arg668Cys], and this result is consistent with the Western blotting results and a partial block in CFTR trafficking. Login to comment
151 Functional Analysis of Chloride Channel Function in CFTR Mutants To determine the impact of p.Gly149Arg, p.Asp443Tyr, p.Gly576Ala, and p.Arg668Cys in single, double, or triple mutants on CFTR chloride channel function, we expressed full-length WT and mutant proteins in HeLa cells, and measured chloride channel activity using single-cell fluorescence imaging and the potential-sensitive probe DiSBAC2(3)(Molecular Probes). Login to comment
152 The CFTR Cl- channel conductance was detected at the plasma membrane in WT CFTR and mutants containing p.Asp443Tyr, p.Gly576Ala, and p.Arg668Cys, whereas no conductance was observed in cells transfected with either GFP negative control or p.Phe508del protein (Figs. 4A and 4B). Login to comment
154 The activity of the p.Asp443Tyr and WT channels was similar. Login to comment
160 Discussion In the present study, we investigated genotype-phenotype correlations and the in vitro consequences of CFTR mutations: four in isolation (i.e., p.Gly149Arg, p.Asp443Tyr, p.Gly576Ala, and p.Arg668Cys) and three complex alleles observed in patients or healthy individuals (i.e., p.[Gly576Ala;Arg668Cys], p.[Asp443Tyr;Gly576Ala;Arg668Cys], and the rarer p.[Gly149Arg; Gly576Ala;Arg668Cys]). Login to comment
165 A: Wild-type CFTR; B: p.Gly576Ala; C: p.Arg668Cys; D: p.Asp443Tyr; E: p.[Gly576Ala;Arg668Cys], F: p.[Asp443Tyr;Gly576Ala;Arg668Cys] are targeted at least to the plasma membrane. Login to comment
173 In contrast, genotypes combining mutants other than p.Gly149Arg, namely p.Arg668Cys, p.[Gly576Ala;Arg668Cys], and p.[Asp443Tyr;Gly576Ala;Arg668Cys], in trans with a CF mutation, were not observed in patients with classical CF, although they were observed in patients with moderate phenotypes, in particular CBAVD. Login to comment
175 This observation is also consistent with the results of the functional studies, which demonstrated residual CFTR function, with p.Asp443Tyr having an effect on protein maturation, and p.Gly576Ala and p.Arg668Cys having an effect on Cl- channel activity. Login to comment
178 This was corroborated by the observation that additional, different mutations occurred on this haplotype (p.Asp443Tyr, p.Gly149Arg, and p.Ser519Gly, the latter being observed only once in the sample from the general population). Login to comment
179 These results have substantial implications for diagnostic and genetic counseling, as they classify p.[Gly149Arg;Gly576Ala;Arg668Cys] or p.Gly149Arg (even if no CF patient was detected with only this mutation) as a CF-causing mutation, and p.Arg668Cys, p.[Gly576Ala;Arg668Cys], and p.[Asp443Tyr;Gly576Ala;Arg668Cys] as CFTR-RD mutations.

32 Surprisingly, only one mutation was identified in her father (p.Asp443Tyr in exon 9), and no mutation was found in her mother. Login to comment
33 The same result (p.Asp443Tyr mutation) was obtained in Bordeaux with case 1. Login to comment
36 The new analysis for this family confirmed the previous results: case 1 carries the c.1392 ϩ 6insC and c.1392 ϩ 12GϾA mutations in intron 9, but not the Asp443Tyr mutation in exon 9. Login to comment
37 On analysis of fresh parental samples at Bordeaux Hospital, the previous parental results were also confirmed, showing that her father must be carrier for Asp443Tyr mutation in exon 9. Login to comment
67 Sequencing of the PCR fragments using CF9.6 and CF9 ϩ 58 primers revealed two heterozygous mutations, c.1392 ϩ 6insC and c.1392 ϩ 12GϾA. However, PCR using the CF9-130 and CF9 ϩ 58 primers (PCR product B, Bordeaux primers), revealed only the GϾT variation at position 1327, corresponding to the p.Asp443Tyr mutation, and not the expected c.1392 ϩ 6insC and c.1392 ϩ 12GϾA mutations.

70 Surprisingly, only the p.Asp443Tyr mutation was detected using another primers pair that spans from intron 8 to intron 9, (CF9-268 and CF9 ϩ 121, PCR C, from intron 8 to intron 9 as for Bordeaux primers). Login to comment
