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.

65 Although each of the remaining 3 mutations (E271K, R401W, and S606L) was identified in only 1 apparently sporadic case of a patient with AMN, a review of the literature indicated that the S606L mutation has been identified in 2 patients with Addison disease only but in no patients with CCALD.33,46 COMMENT MUTATIONS IN THE ALD GENE Because of the low frequency (4%-7%) of large genomic rearrangements in the ALD gene,26,33,34 a detailed nucleotide sequence analysis to detect small nucleotide alterations is required for most cases of ALD.

86 Similar to this mutation, the mu- tationsG1197A(E271K)andC1587T(R401W)wereiden- tified in patients with AMN with no family history of ALD in the present study. Login to comment
