84 The G118T (D443Y) and G157T (V456F) mutations did not significantly affect the splicing pattern, whereas the A146C (Q452P) caused an almost complete inclusion on the exon (96%). Login to comment
137 Identification of Regulatory Elements of Splicing in CFTR Exon 9-Three natural missense mutations with completely different effects on splicing (Q452P (A146C), which induces exon inclusion; A455E (C155A), causing exon exclusion; and V456F (G157T), with no effect) are located within 15 nucleotides.

144 On the contrary, the 153C and the 157T (V456F) variants did not significantly affect the splicing pattern. Login to comment
198 The natural mutations Q456P, A455E, and V456F correspond to A146C, C155A and G157T, respectively. Login to comment

108 Examples are V456F [33] and V520F [34] (labeled C and K, respectively, in fig. 2) which involve residues buried in the interior of the NBD1 subdomain. Login to comment
134 Accordingly, the missense mutation V456F (labeled C in fig. 2), which involves a topohydrophobic position buried in NBD1 (see above), was also reported in a patient suffering from a mild (pancreas-sufficient) form of CF [33]. Login to comment
