80 Many (13 out of 20) of the missense mutations change highly conserved (5/5 species analyzed) amino acid residues (R75Q, G85E, I148T, I506V, R668C, G622D, L997F, I1027T, F1052V, L1096R, I1131V, R1162L, N1303K); others affect amino acid residues conserved in 4/5 species (K68 E, R170H, M470V, V562L, S1235R), or in 3/5 species (R31C and G576A; Tucker et al. 1992).

115 Although the second mutation in this patient is unknown, the R1162Q allele is expected to be very mild, because another mutation in this codon,R1162L was previously classified as a normal variant (Fanen et al., 1992). Login to comment

494 Moreover, two of the CFTR mutations found were previously reported as non-disease causing polymorphisms (R1162L, T1220I), five alterations were described for the first time and have not been demonstrated in a previous study of 640 Spanish CF patients.154 In summary, only 4 of 144 asthmatic patients (2.8%) possessed a verified CF causing mutation (R74W, I148T, T582R, and R1066C).

47 DNA sequence analysis identified a 3617 GϾT heterozygous base change that led to a R1162L mutation. This base change, located 4 bases from the 3=-end of the exon 19 forward primer, was described by Fanen et al. as a polymorphism,15 and was detected in a patient with asthma16 and in a patient with chronic pancreatitis.17 The R1162 residue is conserved across many species,16 and analysis of the effect of R1162L mutation on CFTR protein using the PolyPhen algorithm (http://www.

56 This type of analysis has already been performed for some of the uncommon mutations found in this work (R1162L, S1235R and L997F, see Discussion), while we performed frequency studies for D836Y, P1013L, P5L and D806G. Login to comment
77 By contrast, the pathogenic role of some of the uncommon mutations found (P5L, D836Y, P1013L, D806G, L997F, S1235R, and R1162L) is still a matter of debate (15, 17, 28, 32, 48-58). Login to comment
80 R1162L have also been shown, in previous reports (49, 54), to be less frequent in the general population (0.5%, a percentage confirmed in this work, 0.3% and 0.3%, respectively). Login to comment
81 The absence or lower frequency of L997F, S1235R and R1162L in the general population than in our target group is compatible with a possible pathogenic role of these mutations. Login to comment

198 R1162L is predicted to be a highly deleterious variant by SIFT and damaging by PolyPhen modeling [55] and is included in the CFTR2 mutation database and classified as a variant not causing CF. Login to comment

4 Conclusions: The outcomes in children 2-6 years of age with the L997F, G576A, R1162L, V754M, R668C, R31C, and S1235R variants are consistent with the CFTR2 non-CF-causing classification. Login to comment
