32 Within the northern regions, the western and eastern mutation frequency distributions were remarkably distinct: the western part being characterized by mutation 171721G R A, and the eastern part by mutations R1162X, 2183AA R G, and 71115G R A. Moreover, the island of Sardinia showed the presence of mutation T338I, which was absent from other European CF alleles.

193 The conductance of different T338 mutants varied over almost two orders of magnitude (Fig. 6), although the low conductances estimated for T338N, T338V and T338I should be considered rough approximations only.

195 The central portion of TM6 containing both of these key amino acids (T338 and S341) may therefore be the region where conductance is mainly determined. The low conductance of T338I could also explain why this mutation is associated with CF (Saba et al. 1993), although partial misprocessing (Fig. 1C) may also play a role.

207 All single channel conductances reported in this paper were measured at hyperpolarized potentials; conductance of the mutant channels T338N, T338V and T338I might be significantly lower at depolarized potentials (Fig. 2).

153 Of the 103 test-set mutations, two CF-neutral mutations had a score higher than one standard deviation above the mean (G550R and R933G), and two CF-causing mutations had scores lower than one standard deviation below the mean (G85V and T338I); these four mutations were consistently the most difficult to accurately rank with our method.

85 In total, among the mutations detected in our PS patients, 17 (D579G, E193K, F1052V, 711+5G---~A, G1349D, G85E, R347R R352Q, $549N, 2789+5A---~G, D1152H, R1066H, R334W, T338I, 3849+10kbC---~T, S1251N, R1066C) have been detected in compound heterozygosity with a mutation already classified as severe (AF508, 1717-1G--~A, G542X) and thus can be considered as presumably mild.

86 Of these mutations, seven (G85E, EI93K, 711+5G--qA, R347P, R334W, R352Q, T338|) are located in the first transmembrane (I TM) domain, five (2789+ 5A---~G, RI066H, F1052V, D1152H, R1066C) in the second transmembrane (II TM) domain, four in the nucleo- R334W R347P R352Q T338I E193K 711+.E G85E 1 2 3 4 D579G G->A I S 549N 5 6a 6b 7 8 9 10 11 12 13 3849+11 !11 !

91 Conversely, other presumably mild mutations such as R352Q (three chromosomes), and G85E, Dl152H, 711+5G--~A, R1066H, T338I, R334W, D579G (two chromosomes each), are more frequently detected in the PS cohort, accounting in total for 27.4% of chromosomes.

93 Screening for only eight presumed mild mutations (R352Q, R1066H, G85E, Dl152H, 711+5G---~A, T338I, R334W and D579G) in addition to the predominant four severe mutations (AF508, G542X, 1717-1G-+A and N1303K), would have allowed the identification of 64.5% of the molecular defects in our patients having PS.

4 In molecular screening for CF defects in Sardinians, carried out by DGGE analysis of exons 4 - 7 - 1 0 - 1 1 - 14a-15- 17b-20-21, we identified two novel mutations: a C - T transversionat nt 1145 (T338I) and a C-A transversion at nt 2867 (S912X).

10 The T338I mutation was found in four unrelated CF patients, of whom two had on the other chromosome the AF508 mutation and two an unknown mutation.

11 The analysis of two extragenic markers (XV-2c and KM 19) revealed that all four T338I alleles carried the same haplotype B (KM19/PstI = 2; XV2c/TaqI = 1) (7).

19 Likewise, in the T338I mutation the encoded amino acid switched from apolar to polar (Thr--De), presumably producing an alteration of the pore of the channel formed by the transmembrane segment.

87 Similarly, the baseline chloride transport and ivacaftor response were higher for mutant CFTR forms with mild defects in channel conductance (30-84% of normal; D110H-, R347H, and R352Q-CFTR) [17-19], compared with those with severe defects in CFTR channel conductance (undetectable R334W- and T338I-CFTR) [9,20].

306 However, recent data indicating that VX-770 potentiates channels bearing multiple disease-causing mutations, spread across CFTR, and that VX-770 potentiates one mutant but not another one in the same domain (for example, VX-770 potentiated TM mutants T338I- and R347H- but not S341P- and E92K-CFTR and potentiated cytoplasmic loop mutants E193K- and K1060T- but not R1066M- and L1065P-CFTR) do not support this conclusion (30, 38).
