5 The spectrum of novel mutations consists of 3 frameshift (p.Ser284fs*16, p.Glu380Argfs*21 and p.Thr254Argfs*82); a deletion (p.Ser572_Asp575del); a splicing mutation (c.1081+5G.C) and 3 missense mutations (p.Ala341Asp, p.His420Pro and p.Tyr547Cys). Login to comment

88 These new changes included 3 frameshifts (p.Ser284fs*16; p.Glu380Argfs*21; p.Thr254Argfs*82); a deletion (p.Ser572_Asp575del), a splicing mutation (c.1081+5G.C) and three single base pair substitutions (p.Ala341Asp, p.His420Pro and p.Tyr547Cys). Login to comment
94 It was verified by functional studies that the missense substitutions p.Ala341Asp, p.His420Pro and p.Tyr547Cys are disease-causing mutations. Login to comment
97 No protein was observed in western blot assays and b-oxidation was defective in fibroblast cultures of the patient with the p.Ala341Asp mutation (Figure 3 and 4). Login to comment
101 PolyPhen predicted that p.Ala341Asp is possibly damaging, and p.Tyr547Cys and p.His420Pro can be probably damaging (Table 2). Login to comment
126 Each line was loaded with the same amount of total protein extracts, as verified with anti-b-actin protein. Line 1: healthy fibroblasts, line 2: X-linked adrenoleukodystrophy fibroblasts, line 3: c.1081+5G.C, line 4: p.Ala341Asp. Login to comment
139 For the p.Ala341Asp, p.Tyr547Cys and p.His420Pro alleles, we did not observe protein in western blots and the level of b-oxidation was deficient (Figures 1, 2, 3, 4 and data not shown). Login to comment
140 These results confirm that p.Ala341Asp, p.Tyr547Cys and p.His420Pro are the causing disease mutations in each patient. Login to comment
