4 Thirteen mutations were novel, i.e. p.R280L, p.P580L, p.G343V, p.S108X, p.R259W, p.P534R, p.fs A246, p.L576P, p.K602X, p.A314P, p.N148D, p.H283R, and p.fs R89. Login to comment
53 Thirteen mutations were novel, i.e. p.R280L, p.P580L, p.G343V, p.S108X, p.R259W, p.fs A246, p.L576P, p.P534R, p.K602X, p.A314P, p.N148D, p.H283R, and p.fs R89, 9 of which were missense mutations. Login to comment
56 The mutations p.S108X and p.R259W occurred simultaneously in the same family and they lined tandemly on the same allele of ABCD1 gene, a phenomenon called multiple mutations. Login to comment
82 Two sets of multiple mutations, i.e. [p.S108X; p.R259W] and [p.K217E; p. V489V], were identified, which were new according to the international database (http://www.x-ald.nl), and it was the first time that multiple mutations were found in the ABCD1 gene in Chinese population. Login to comment

32 Fragments that covered the p.Ser108X and p.Arg259Trp mutations (pedigree 1) or p.Lys217Glu and p.Val489Val mutations (pedigree 2) of the ABCD1 gene were amplified with the primers listed in●▶ Table 1 [7]. Login to comment
37 323C>A and c.775C>T) lined tandemly were detected in one allele of the ABCD1 gene, leading to the substitution of the normal serine with stop codon at codon 108 (p.Ser108X) and the substitution of the normal arginine with tryptophan at codon 259 (p.Arg259Trp). Login to comment
61 The second missense mutation (p.Arg259Trp) has not been reported previously. Login to comment
66 Fourthly, the in silico analysis of pathogenicity was performed using PolyPhen, and the prediction result revealed that p.Arg259Trp is probably damaging, suggesting that the mutation is pathogenic. Login to comment
67 For the multiple mutation combination p.Ser108X and p.Arg259Trp, it is rather obvious that the nonsense mutation is disease-causing by itself, as it results in no ALDP. Login to comment
