84 Interestingly, the five previously described SNPs (rs17782508, rs2301345, rs4148077, rs4148078, and rs3742801) that are in complete linkage disequilibrium were significantly less frequently represented in the patients with Japanese AMN than in the controls in the Japanese population (p=0.0468), whereas Table 2 Identified ABCD1 mutations: mutations of ABCD1 that result in amino acid substitutions or in-frame deletions Patient number Phenotype Mutation of ABCD1 Effect of mutation of ABCD1 Position of mutation 13 CCALD 709C>T S108L Loop1 14 CCALD 709C>T S108L Loop1 15 CCALD 829A>G N148S TM2 16 CCALD 1026A>G N214D TM3 17 CCALD 1182G>A G266R Between TM4 and EAA-like 18 CCALD 1324T>Ca L313P Between EAA-like and TM5 19 CCALD 1938C>T R518W Walker A 20 CCALD 1939G>A R518Q Walker A 21 CCALD 2017A>G Q544R Between Walker A and Cons 22 CCALD 2017A>G Q544R Between Walker A and Cons 23 CCALD 2065C>T P560L Between Walker A and Cons 24 CCALD 2065C>T P560L Between Walker A and Cons 25 CCALD Del. 2145-2156 Del.

4 The second, a de novo C709T transition, results in a substitution Ser 108 Leu between the second and the third putative transmembrane segments, in a childhood case. Login to comment
43 Moreover studies regarding a homologous peroxisomal transmembrane protein (PMP70) have suggested a role of the corresponding region for targeting and insertion in the peroxisomal membrane.14 The mutation C709T results in the substitution of serine 108 for leucine in the loop between the second and the third putative transmembrane segments.

44 Other mutations in this segment have been described that cause ALD including the substitution of serine 108 for tryptophan described in a ChALD and in an AMN.9 The authors9 demonstrated that the substitution of this serine for tryptophan showed decreased ALDP immunoreactivity and a weak 75 kD ALDP band on Western blotting indicating that the substitution of serine 108 probably results in the synthesis of an unstable protein that is rapidly degraded in the cytosol.
