122 Similar recommendations have been made by other groups to add mutations that would increase detection in the Hispanic popula- tin.13,18,32 In the African American population, the A559T mutation was the 4th most common mutation among CF patient chromosomes (2.78%) and the third most frequent among CF carriers (6.38%) and as such would warrant inclusion, with 711ϩ5GϾA (0.93%), in any screening program serving an African American population.

27 If the mutations that have also been found in the white population were excluded, the 3120+1G→A mutation would account for 53% of African-American CFTR mutations.4 This mutation has also been found in a black CF patient whose father, the 3120+1G→A carrier, is from Cameroon.8 More recently, the mutation has been identified in three Greek families10 and it has also been shown to be a common CFTR mutation (25% of their CF chromosomes) in Saudi Arabia.11 In an attempt to establish how common CF is in African populations, healthy unrelated subjects were screened for four mutations: 3120+1G→A,9 A559T,12 S1255X,13 and 444delA.14 They occur in African-American CF patients at frequencies of 12.2%, 2.0%, 1.4%, and 0.7%, respectively.4 Subjects and methods DNA samples from 208 San and 1152 unrelated, healthy African blacks from southern, western, and central Africa were studied.

59 With a 95% confidence interval, the frequencies of subjects who are carriers for these mutations are low in African populations (0-0.0074 for A559T and S1255X; 0-0.0092 for 444delA)18 and the allele frequencies would be even lower.

223 They include another deletion mutation at amino acid position 507 (⌬I507), several missense mutations (F508C, G551D, G551S, A455E, R553Q, P574H, S549N, A559T), and some nonsense mutations (G542X, R553X, Q493X).

360 The CFTR NBD1 model that results (Fig. 6) gathers the disease causing mutations in three different clusters: (1) mutations affecting the nucleotide binding pocket and the putative general base: A455E, G458V, E504Q AI507 AF508 P574H; (2) mutations in motif C which are probably related to an interaction with region D: S549[R,N,I] G551[S,D], R553Q; and (3) mutations within or near motif B, L558S, A559T, R560T, Y563N and mutations S492F and G480C.

110 Actually, two African mutations (p.A559T and c.3120+1GNA) have been found in two regions with high African admixture in Colombia (Bolivar and Antioquia-Choc&#f3;) [14], and the c.3120+1G-NA mutation has also been found in Brazil [15, 26], with a frequency of 4% in Rio de Janeiro, and Argentina (Oller Ramirez, personal communication).

115 The extended panel detected 21.7% more mutations (P < 0.01) using six additional race-specific (R75X, G480C, A559T, 2307insA, S1255X, and 3791delC) and seven panethnic variants (see Supplementary Table S2 online).

357 Moreover, a large ''hot spot`` region for natural CFTR mutations is located at the NBD1:ICL4 interface, involving (1) six ICL4 positions (H1054D, G1061R, L1065P, R1066H/R1066C, F1074L, and L1077P), which line the path followed by F508 during the MD1 conformational transition from its initial to its final position, and (2) seven positions in NBD1 (S492F, I507del, F508del, V520F, A559T, R560K/R560T, and A561E) (Fig. 7c).
