16 Mutations detected in both groups included 7 missense mutations (S13F, P67L, G98R, S492F, G970D, L1093P, N1303K) and 9 deletion, frameshift, nonsense or splicing mutations (R75X, G542X, ⌬F508, 451-458⌬8 bp, 5T, 663⌬T, exon 13 frameshift, 1261؉1G3A and 3272-26A3G). Login to comment

37 MATERIALS AND METHODS Cell Lines Baby hamster kidney (BHK) cells, stably expressing the wt and mutant (G91R, L346P, L1093P, N1303K, ⌬F508, 4D, 1218X, 1158X, and 823X) CFTR with three tandem hemagglutinin (HA)-epitope (3HA) inserted into the fourth extracellular loop, were isolated and maintained as described previously (Sharma et al., 2004; Du et al., 2005). Login to comment
252 Four CF mutations, G91R (Xiong et al., 1997), L346P (Choi et al., 2005), L1093P (Seibert et al., 1996), and N1303K (Gregory et al., 1991), localized to the transmembrane (TM) 1 and TM6 in MSD1, the cytosolic loop (CL) 4, and in the NBD2, respectively (Figure 7a). Login to comment
274 Remarkably, the G91R, L346P, ⌬F508, 4D, and L1093P mutations, regardless of their location, profoundly augmented the protease susceptibility of the NBD2 (ϳ30 kDa), probed with the M3A7 Ab (Figure 7g and Supplemental Figure S7c). Login to comment
301 One of the most important observations of this study is that the NBD2 conformational stability was dramatically impaired regardless the localization of mutations (G91R, L346P, ⌬F508, 4D, and L1093P) in the NBD1, TM1, TM6, or CL4 (Figure 6e). Login to comment

5 Functional analysis using forskolin-stimulated efflux of 125 I in HEK cells transfected with an ABCC7 construct harboring the L1093P mutation confirmed that cAMP-mediated anion efflux was abnormal, but some function was preserved. Login to comment
6 Analysis of parental DNA established that N1303K was of English origin, while L1093P was of Greek, Irish or Native American (Cherokee) origin. Login to comment
7 Given the intensive screening for CF mutations in European populations, we hypothesize that L1093P is of Native American origin. Login to comment
12 Preliminary evidence indicates that the L1093P mutation might be of Native American origin. Login to comment

51 The father was heterozygous for N1303K, and the mother for L1093P (Fig. 1a). Login to comment

66 To assess the anion channel function of CFTR harboring the L1093P mutation, HEK cells transiently expressing either plasmid alone, WT- ABCC7, or L1093P- ABCC7 were assayed for 125 I efflux in the absence and presence of forskolin. The extent to which the rate of efflux increases following forskolin is correlated with the number of active CFTR channels in the membrane (n), their open probability (Po), and their conductance (γ). Login to comment
67 As shown in Fig. 1c, efflux from the L1093P mutation was significantly reduced relative to WT ABCC7, but was slightly but significantly elevated relative to vector alone. Login to comment
70 The present mutation, L1093P, was found in association with N1303K in a pancreatic insufficient subject who had lung disease severe enough to require a transplant. Login to comment
72 The clinical phenotype and our physiological data indicate that L1093P should also be considered a severe mutation, yet it does retain some function, in contrast with mutations such as ∆F508-ABCC7 and G551D-ABCC7 that are indistinguishable from vector controls in this assay. Login to comment
73 Dysfunction of L1093P. Login to comment
74 The basis of the dysfunction of L1093P was not determined. Login to comment
75 L1093P occurs in the part of exon 17b, residues 1035-1102, that forms the 4th intracellular loop of ABCC7(Cotton et al. 1996; Seibert et al. 1996). Login to comment
81 Possible Native American Origin of L1093P. Login to comment
85 The L1093P mutation was maternal. Login to comment
86 Previous comprehensive screenings of European populations have not detected the L1093P mutation. Login to comment
88 Because of the high sensitivity of DGGE, which is essentially 100% when optimized (Gejman et al. 1998), these figures indicate that the L1093P mutation, if present in these populations, probably accounts for < 0.2% of CF mutations. Login to comment
89 Therefore, we consider the alternative hypothesis that L1093P might be of Native American origin. Login to comment

315 The NBD2 transmission interface was also found to be particularly important for CFTR assembly as processing mutations in other domains that cause cystic fibrosis (such as èc;F508 in NBD1, G91R in TMD1, L1093P in TMD2) were found to impair the conformational stability of NBD2 (54).
