66 Of note, in the case of some other changes, the results were unclear - for example, in the case of already known mutations published in the CFTR Mutation Database: T1053I (according to Align-GVGD: 'less likely to be pathogenic`, score C0, PolyPhen: 'possible damaging`, score 0.816 and SIFT: 'deleterious`, score 0.01), similarly for L467F (Align-GVGD: 'less likely`, class C0, PolyPhen: 'probably damaging`, score 0.994 and SIFT: 'deleterious`, score 0.03).

113 For example, the diagnosis of CF has not been confirmed following the identification of the T1053I and L467F mutations. Login to comment

94 The mutation p.G85E has been shown to reduce gene activity by altering the tertiary structure of the CFTR channel;31 p.R334W leads to loss of conductivity of the large conductance channel of CFTR;32 p.T338I is a mutation in the sixth transmembrane segment of the MSD1 domain; p.L467F and p.I506T are mutations in the first nucleotide binding domain (NBD1); and p.N1303K is a mutation in the second nucleotide binding domain (NBD2) of the CFTR protein.

95 Both domains are conserved in the ATP-binding cassette transporters.33 In addition, mutations p.D110H, p.R334W, p.T338I, p.L467F, and p.P1013L altered predicted exon splicing enhancer motifs in the CFTR gene, suggesting that they may have a deleterious effect on splicing. Login to comment
