1 Nine of these (I601F, L610S, A613T, D614G, I618T, L619S, H620P, G628R and L633P) resulted in aberrant processing. Login to comment
66 The mutations that gave rise to a protein that was not able to proceed to the 190 kDa form (I601F, L610S, A613T, D614G, I618T, L619S, H620P, G628R and L633P; Table 2) are therefore class two mutations (17), where the disease phenotype is caused by the absence of sufficient CFTR protein at the cell surface.

7 One of these mutants, L619S, exhibits no detectable function, whereas the other two, D614G and I618T, exhibit partial activity as chloride channels. Login to comment
40 One of these RD1 mutants, L619S, failed to exhibit chloride channel function in two electrode voltage clamp studies and hence is likely to reside in a region critical for this activity. Login to comment
130 Single Channel Analysis Reveals Defects in Channel Opening by CFTR D614G and I618T-We know from the previous whole cell studies that the L619S mutation causes severe dysfunction of the CFTR channel activity because, despite expression of this mutant protein at the cell surface (Fig. 3), cyclic AMP-activated chloride currents were not detected (Fig. 4).

173 Mutation of the leucine residue at position 619 to serine has a profound inhibitory effect on channel activity, such that whole cell currents cannot be detected despite significant cell surface expression. Login to comment

102 As the L619S change was present in conjunction with the previously known rare sequence variant 1716 G--->A (Kerem et al. 1990) on the same allele, it was difficult to decide whether both sequence changes were required to cause the disease. Login to comment
