50 Of the 8 additional CFTR gene sequence alterations detected using extensive CFTR exon screening, 5 have been described rarely in the CF population (L206W [identified in 2 subjects], P67L, 1677delTA, R117L, and 4016insT).60 One mutation, D979A, was previously identified in a Vietnamese CBAVD patient.60 Interestingly, our CBAVD subject with D979A (also a carrier of IVS8-5T) was of Vietnamese descent as well.

251 The mild pulmonary phenotype seen in patients with genotype I-II/III-V is consistent with previous reports where a few rare mutations such as A455E, R117H, 3849+10kbCRT, 2789+5GRT, and P67L (all class IV or V mutations) are clearly linked to a better pulmonary outcome.13 14 26-28 The findings observed in this study support the hypothesis that differences in CF pulmonary phenotype could be related to the effect of the genotype on CFTR protein production and function.

182 The previously reported P67L mutation has a similar effect on CFTR function as the P67S mutation As shown above the P67S mutation reduces ΔGIBMX/ Fsk by decreasing the surface expression of the mutated CFTR channels. Login to comment
194 same position in the CFTR protein has previously been described, P67L, and was reported to cause a dominant mild phenotype of CF [29], i.e. if a patient is heterozygous for this mutation, he suffers from a mild CF even when the mutation on the other allele is known to cause severe CF (e.g. ΔF508). Login to comment
196 Therefore, we decided to investigate the P67L mutation to compare its effect with the effect of the P67S mutation. Login to comment
197 In two different batches of oocytes we found that ΔGIBMX/Fsk was similarly decreased in P67S CFTR (30.2 ± 2.8 µS, n=9) and P67L CFTR (14.3 ± 4.1 µS, n=9) expressing oocytes compared to ΔGIBMX/Fsk of wild-type CFTR (157.0 ± 24.4 µS, n=9, see figure 5) expressing oocytes. Login to comment

201 Experiments were essentially performed as described in figure 2 to determine ΔGIBMX/Fsk in matched oocytes from two different batches expressing either wild-type CFTR, P67S or P67L CFTR (N=2, n=9,** p<0.01, *** p<0.001). Login to comment
205 3) The mutation P67L, a previously described dominant mild form of CFTR [29], reduced the CFTR whole-cell conductance to about the same level as the P67S mutation. Login to comment
223 This P67L mutation was found to confer a dominant mild effect, i.e. compound heterozygotes carrying the P67L mutation on one allele and a severe CFTR mutation (e.g. ΔF508) on the other allele have a mild phenotype. Login to comment
224 Gilfillan et al. [29] reported that none of the P67L compound heterozygotes they investigated showed consistently raised sweat chloride concentrations and 77% of the 13 patients investigated were pancreatic sufficient. Login to comment
225 Another study [31] reported one patient with a negative sweat test and pancreatic sufficiency, who was also heterozygous for P67L. Login to comment
226 To our knowledge no functional data have yet been reported for the P67L mutant. Login to comment
227 In our study we found that the P67L mutant had a similar inhibitory effect on the CFTR whole-cell conductance as the P67S mutant. Login to comment
231 Thus, in the oocyte expression system the inhibitory effect of the ΔF508 mutation seems to be rather similar to that observed in the present study for the P67S and P67L mutant channels. Login to comment
236 Thus, the temperature sensitivity of the ΔF508-CFTR may explain its more severe phenotype compared to the P67S or the P67L mutations. Login to comment
237 In any case, the mild CF phenotype of patients with the P67S or the P67L mutations suggests that the residual function of these mutant channels is sufficient to prevent severe symptoms. Login to comment

39 However, a significantly higher level (P b 0.05; ANOVA followed by Tukey's multiple comparisons test; n = 3-6) of mRNA expression was measured for P67L-, E92K-, and A455E-CFTR (Fig. 1). Login to comment
43 Mutations such as P67L-, E56K-, and A455E-CFTR exhibited intermediate levels of mature CFTR, which are consistent with less severe defects in CFTR processing (mature CFTR protein for P67L-, E56K-, and A455E-CFTR were 28.4&#b1; 6.8, 12.2&#b1;1.5, and 11.5&#b1;2.5% of normal, respectively).

106 For example, patients with CF who have the class II mutation, P67L, along with a severe CF-causing mutation (most commonly F508del), have a mean sweat chloride concentration of 57 mmol/L [21], which is lower than that in patients with CF who carry two copies of the most common class II mutation, F508del (~100 mmol/L).

36 Further in vitro data suggest that other CFTR proteins with residual function may also be potentiated by ivacaftor, including those with mutations that affect conductance (e.g. R117H, D110H), mildly affect CFTR processing (e.g. E56K, P67L) or have uncharacterized effects (e.g. D110E, S1235R) [5, 16].

116 Supporting this hypothesis is the fact that VX-809 has been shown to act on MSD1 folding and that it also rescues functional defects in CFTR caused by disease-related mutations in the vicinity of the three amino acids highlighted here (P67L, L206W) [16]. Login to comment

0 e journal.publications.chestnet.org Improved Clinical and Radiographic Outcomes After Treatment With Ivacaftor in a Young Adult With Cystic Fibrosis With the P67L CFTR Mutation Shatha Yousef, MD; George M. Solomon, MD; Alan Brody, MD; Steven M. Rowe, MD, MSPH; and Andrew A. Colin, MD The underlying cause of cystic fibrosis (CF) is the loss of epithelial chloride and bicarbonate transport due to mutations in the CF transmembrane conductance regulator (CFTR) gene encoding the CFTR protein.

3 P67L is a class 4 conductance (nongating) mutation exhibiting residual CFTR function. Login to comment
4 We report marked clinical improvement, normalization of spirometry, and dramatic reduction in radiographic structural airway changes after .1 year of treatment with ivacaftor in a young adult with the compound heterozygous genotype P67L/F508del CFTR. Login to comment
13 This includes P67L, a class 4 conductance mutation that exhibits residual CFTR function and relatively preserved CFTR expression, has a worldwide prevalence of 0.2%, and is the sixth most common mutation in Scotland.9 We report a case of a patient with CF who is a complex heterozygote for P67L/F508del with severe CF lung disease who improved significantly shortly after starting treatment with ivacaftor, including evidence of resolving structural lung disease.

14 Case Report The patient is an 18-year-old woman of Scottish descent with genotype F508del/P67L. Login to comment
34 P67L is generally considered a CFTR mutation with reduced conductance.12 Furthermore, Sosnay and colleagues13 reported lower levels of mature glycosylated protein compared with wild-type CFTR (low band C/B ratio), suggesting an additional abnormality caused by ineffective maturation of P67L.

35 Van Goor et al12 studied the in vitro effect of ivacaftor on multiple mutant CFTR forms due to missense mutations, including mutations that cause abnormal protein processing and reduced CFTR activity at the plasma membrane, such as P67L. Login to comment
36 In vitro, ivacaftor caused a significant increase in chloride current in epithelial cells expressing these mutations.12 Combined with data illustrated by this case, results strongly indicate that P67L is among the mutations that can Figure 1 - Comparison of the average FEV1 of all available measurements obtained during the years prior to ivacaftor and after the start of ivacaftor treatment.

39 Moreover, the observed course of this patient supports the notion that ivacaftor could exhibit a class effect on CFTR mutations with decreased conductance but residual function and expression, such as P67L. Login to comment
44 Currently, evaluation of conductance mutations has been limited to the R117H mutation, which also exhibits abnormal gating.15 Although ivacaftor has been reported to reduce the stability of some CFTR forms in vitro, including P67L, any detrimental effect on cell surface levels was not apparent based on a robust and sustained clinical response in this individual.16,17 Our positive experience emphasizes the need for definitive studies to test the potential benefit of ivacaftor for patients with CF with nongating missense mutations.
