6 Only six mutations (Y174S, G277R, FsE471, R518Q, P543L, and R554H) were found in more than one family. Login to comment
7 Mutations G277R, P543L, and R554H were the most frequent, each of them being found in three patients (5%). Login to comment
41 The novel mutations included 12 amino acid substitutions [R17H, V102E, R120P, N148Y, G277R (829G> C), L279P, A396T, M501L, K533E, D561V, R617L, and S656F], five stop codon (S108X, S358X, W524X, Q567X, and S572X), one acceptor splice site mutation (IVS1-3C > G), and nine frameshift mutations as a consequence of four deletions [FsS453 (1359delT), FsG473 (1420delA), FsA616 (1847delC), and Fs N390 (1171delTCCTGACAGC)], one insertion [FsW326 (979insT)], and three complex mutations [FsQ38 (115delTG CCTGGCCCCGGCCAGinsGCA, FsF252 (757 delCTCACGGCC insGAGG), and FsL504 (1515 delCACAGinsGCA)].

67 With respect to the 12 missense mutations (R17H, V102E, R120P, N148Y, G277R, L279P, A396T, M501L, K533E, D561V, R617L, and S656F), only in four cases (L279P, K533E, R554H, and S656F mutations), three of which (K533E, R554H, and S656F) affect adenosine triphosphate-binding domain or boundaries, could negative ALDP protein expression be established.

72 Only six mutations (Y174S, G277R, FsE471, R518Q, P543L, and R554H) have been found repeated in patients belonging to different families. Login to comment
74 In contrast, mutations G277R, P543L, and R554H are the most frequent in the Spanish population, each one accounting for three independent patients (5%) with different phenotypes, as occurs in other populations (for more information: http://www.x-ald.nl). Login to comment

61 Here, a mutation (G277R) was detected, and the signal intensities around the mutation were reduced because of the mismatch of the mutation site. Login to comment
