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.

68 However, several lines of evidence suggest that all these mutations may be pathogenic: (a) after screening the entire coding region of the ABCD1 gene, no other mutation was found in these patients, except for patient A302, who has two changes at the same allele: R17H and FsG473, the later being most certainly the disease-causing mutation.

69 Therefore, although we did not detect it in controls, it is very probable that R17H is a new polymorphism; (b) none of the novel mutations was detected when 100 normal chromosomes were analyzed; (c) all the amino acid residues, except R120, are conserved among the proteins belonging to the ABC subfamily D.
