83 Four of the natural substitutions, C31T (Q414X), G61A (G424S), T122G (I444S), and C155A (A455E), significantly decreased exon 9 inclusion to 48, 30, 40, and 16%, respectively, whereas only a modest decrease was evident for N418S. Login to comment
91 We have evaluated the possibility that some of the changes in the splicing pattern induced by the natural substitutions in exon 9, particularly the Q414X, might be related to nonsense mediated altered splicing. Login to comment
129 On the other hand, in the F1 and F2 minigenes, C31T creates a stop codon (Q414X), whereas C155A does not. Login to comment

7 We also identified a novel missense mutation (V456F) and a novel nonsense mutation (Q414X) within the coding region of exon 9. Login to comment
9 In contrast, the pancreas-insufficient Q414X/AF508 compound heterozygote suffered from a severe form of the disease, indicating that alternative splicing of exon 9 does not overcome the deleterious effect of a stop codon within this exon. Login to comment

83 The novel nonsense mutation Q414X was detected in another German CF family by direct sequencing of a PCR product whose SSCP pattern did not match the pattern that we expected from the repeat genotype. Login to comment

89 These results strongly suggest that Q414X is disease-causing by itself and produces a severe phenotype despite alternative splicing. Login to comment
111 The apparent abundance of exon 9 skipping in healthy individuals needs to be taken into consideration when a disease-causing role is attributed to mutations within the coding region of exon 9, such as the Q414X and V456F mutations identified in this study. Login to comment
124 Here, we have described the first case of a nonsense mutation Q414X within this alternatively spliced exon in a patient with prominent pulmonary and gastrointestinal CF symptoms. Login to comment
126 Any CFTR gene product produced by the Q414X allele would be truncated or lacking exon 9. Login to comment
127 The most simple conclusion drawn from the severe clinical course of the compound heterozygote Q414X/AF508 is that the deleterious effects of the Q414X mutation cannot be overcome by exon skipping because exon 9- CFTR cannot compensate for full-length CFTR. Login to comment
