Abstract [show]
Adrenoleukodystrophy (ALD) is an X-linked disorder affecting primarily the white matter of the central nervous system occasionally accompanied by adrenal insufficiency. Despite the discovery of the causative gene, ABCD1, no clear genotype-phenotype correlations have been established. Association studies based on single nucleotide polymorphisms (SNPs) identified by comprehensive resequencing of genes related to ABCD1 may reveal genes modifying ALD phenotypes. We analyzed 40 Japanese patients with ALD. ABCD1 and ABCD2 were analyzed using a newly developed microarray-based resequencing system. ABCD3 and ABCD4 were analyzed by direct nucleotide sequence analysis. Replication studies were conducted on an independent French ALD cohort with extreme phenotypes. All the mutations of ABCD1 were identified, and there was no correlation between the genotypes and phenotypes of ALD. SNPs identified by the comprehensive resequencing of ABCD2, ABCD3, and ABCD4 were used for association studies. There were no significant associations between these SNPs and ALD phenotypes, except for the five SNPs of ABCD4, which are in complete disequilibrium in the Japanese population. These five SNPs were significantly less frequently represented in patients with adrenomyeloneuropathy (AMN) than in controls in the Japanese population (p=0.0468), whereas there were no significant differences in patients with childhood cerebral ALD (CCALD). The replication study employing these five SNPs on an independent French ALD cohort, however, showed no significant associations with CCALD or pure AMN. This study showed that ABCD2, ABCD3, and ABCD4 are less likely the disease-modifying genes, necessitating further studies to identify genes modifying ALD phenotypes.

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.
