129 Of those exon 13 mutations that were not detected at 60°C, G628R and Q685X (see Fig. 4) each lies within a domain with a melting temperature of 56°C. Login to comment
130 It is therefore understandable that G628R and Q685X did not resolve at 60°C. Login to comment

2 We mutated CFTR amino acids located in the betac5-betac6 hairpin, within the betac5 strand (H620Q), within the beta-turn linking the two beta strands (E621G, G622D), as well as within (S623A, S624A) and at the extremity (G628R) of the betac6 strand. Login to comment
3 Functional analysis reveals that the current density was largely reduced for G622D and G628R channels compared with wt CFTR, similar for E621G and S624A, but increased for H620Q and S623A. Login to comment
4 For G622D and G628R, the abnormal activity is likely due to a defective maturation process, as assessed by the augmented activity and mature C-band observed in the presence of the trafficking corrector miglustat. Login to comment
5 In addition, in presence of the CFTR activator benzo[c]quinolizinium, the CFTR current density compared with that of wt CFTR was abolished for G622D and G628R channels, but similar for H620Q, S623A, and S624A or slightly increased for E621G. Login to comment
6 Finally, G622D and G628R were activated by the CFTR agonists genistein, RP-107, and isobutylmethylxanthine. Login to comment
33 We have mutated these two glycine residues in aspartic acid (G622D) and arginine (G628R) and considered other mutants in their neighborhood (H620Q, E621G, S623A, and S624A). Login to comment

87 RESULTS Expression of the NBD1 C-terminal CFTR Mutants-We have introduced EGFP-tagged CFTR proteins into HEK293 cells, wt CFTR and six CFTR mutants, i.e. H620Q, E621G, G622D, S623A, S624A, and G628R. Login to comment

110 Third, the current densities for G622D and G628R, although not abolished, are both significantly reduced (p Ͻ 0.001) compared with wt (supplemental Table 2). Login to comment
115 Because we observed a pronounced reduction of the current density for the mutants G622D and G628R, we incubated transfected HEK293 and BHK-21 cells with this corrector and analyzed the corresponding CFTR activity. Login to comment
117 Similarly in BHK-21 cells the iodide efflux responses stimulated by Fsk and genistein was significantly increased for G622D and G628R after treatment with the corrector (Fig. 4B). Login to comment
118 This observation indicates that the diminution of cAMP-induced Cl- current is probably due to the diminution or to the absence of a mature form of G622D and G628R mutants. Login to comment
119 In support of this hypothesis, Western blot analysis of cells treated with miglustat shows enhanced mature C-band for G622D and G628R mutants (Fig. 4A). Login to comment
133 MPB-91 stimulated the Cl- current for each CFTR mutants studied except the glycine mutants G622D and G628R (Fig. 6 and supplemental Table 3). Login to comment
134 For them, comparison of the corresponding IV slope (Fig. 7A) did not reveal significant differences between basal condition (I/V slope of G622D, 0.032 Ϯ 0.001, n ϭ 7; G628R, 0.046 Ϯ 0.002, n ϭ 5) and in presence of 50 ␮M MPB-91 (I/V slope of G622D, 0.037 Ϯ 0.001, n ϭ 7; G628R, 0.053 Ϯ 0.003, n ϭ 5) indicating the absence of a response of the two mutated channels to that agent. Login to comment
136 Results in Fig. 8 show a potentiation of the cAMP-dependent Cl- current by MPB-91 for wt channels but neither for G622D nor G628R FIGURE 5. Login to comment
141 We also tested analogues of MPB-91 (12), but again for the mutant G622D or G628R, the Cl-channel function of CFTR was not stimulated by MPB-95 and MPB-97 (Fig. 9A). Login to comment
143 Importantly, all of these CFTR activators stimulated the Cl-channel activity of G622D and G628R CFTR, suggesting the relative specificity of the effect observed in the presence of the benzoquinolizinium drugs (Fig. 9B). Login to comment
146 Using Western blot analysis, we now observed a strong decrease of the mature-glycosylated form for the two mutants G622D and G628R. Login to comment
158 Consistently, the defect in the maturation process induced by the G622D and G628R mutations, which causes the retention of the mutated CFTR protein, can be clearly explained by the key role of these glycine residues at the structure level. Login to comment
184 In contrast, for the two mutants G622D and G628R, no activation was recorded in the presence of MPB-91 or other MPB compounds. Login to comment
187 However, this is not the case since xanthine (isobutylmethylxanthine), RP-107, or iso- flavonoide (genistein) successfully stimulated the channel activity of G622D and G628R CFTR channels. Login to comment
188 Therefore, one could hypothesize that the mechanism of activation of CFTR by MPB was itself affected by the mutations G622D and G628R and that the binding site of MPB might be located, on the folded protein, in the vicinity of the last beta hairpin of CFTR NBD1. Login to comment
189 However, the perturbation induced by the G622D and G628R mutations on the overall NBD1 structure might be felt at long range and thus influence potential binding sites, which may be distant at the three-dimensional level. Login to comment

11 However, a clear statement on the pathogenicity of a mutation is difficult to obtain, in particular for missense mutations.2,3 Moreover, the existence of at least two mutations or sequence variations on the same allele, named complex alleles, complicates genetic counseling.4-11 p.Ser1235Arg (3837T4G or c.3705T4G), initially reported by Cuppens et al.12 with a second mutation on the same allele, p.Gly628Arg, is located in a poorly conserved region in the second nucleotide binding fold (NBF2).

134 These data are consistent with previous functional study of this locus in combination with alleles found at p.Met470Val and p.Gly628Arg loci.13 Wei et al.13 demonstrated that the p.Ser1235Arg CFTR protein does not cause change in the chloride transport activity. Login to comment
