ABCD1 mutations and the X-linked adrenoleukodystrophy mutation database: role in diagnosis and clinical correlations.
Hum Mutat. 2001 Dec;18(6):499-515., [PMID:11748843]
Abstract [show]
X-linked adrenoleukodystrophy (X-ALD) is caused by mutations in the ABCD1 gene, which encodes a peroxisomal ABC half-transporter (ALDP) involved in the import of very long-chain fatty acids (VLCFA) into the peroxisome. The disease is characterized by a striking and unpredictable variation in phenotypic expression. Phenotypes include the rapidly progressive childhood cerebral form (CCALD), the milder adult form, adrenomyeloneuropathy (AMN), and variants without neurologic involvement. There is no apparent correlation between genotype and phenotype. In males, unambiguous diagnosis can be achieved by demonstration of elevated levels of VLCFA in plasma. In 15 to 20% of obligate heterozygotes, however, test results are false-negative. Therefore, mutation analysis is the only reliable method for the identification of heterozygotes. Since most X-ALD kindreds have a unique mutation, a great number of mutations have been identified in the ABCD1 gene in the last seven years. In order to catalog and facilitate the analysis of these mutations, we have established a mutation database for X-ALD ( http://www.x-ald.nl). In this review we report a detailed analysis of all 406 X-ALD mutations currently included in the database. Also, we present 47 novel mutations. In addition, we review the various X-ALD phenotypes, the different diagnostic tools, and the need for extended family screening for the identification of new patients.

Identification of seven novel mutations in ABCD1 by a DHPLC-based assay in Italian patients with X-linked adrenoleukodystrophy.

Abstract [show]
We report the molecular findings in 14 patients (12 families) with X-linked adrenoleukodystrophy (X-ALD, MIM# 300100), a well-defined peroxisomal disorder attributed to mutations in the ABCD1 gene on chromosome Xq28. With the aims of determining the spectrum of mutations and developing an efficient molecular genetic test for analysis of at-risk women whose carrier status is unknown, and to offer molecular confirmation of their status to obligate heterozygotes, regardless of their clinical status, we carried out molecular screening by setting up a denaturing high-performance liquid chromatography (DHPLC)-based protocol. We identified eleven hemizygous base changes in ABCD1, including seven new mutations (c.145underscore;146ins4, c.264C>G, c.919C>T, c.994C>T, c.1027G>A, c.1508T>C, and c.1540A>C, resulting in the p.Pro193fs, p.Cys88Trp, p.Gln307X, p.Gln332X, p.Gly343Ser, p.Leu503Pro, and p.Ser514Arg changes, respectively). Adding new variants to the repertoire of ABCD1 mutations in X-ALD, our data provide an efficient, cost-effective, and reliable DHPLC detection protocol for mutation screening of X-ALD families.

77 Interestingly, another substitution at the same residue (p.Gly343Asp) has already been associated with X-ALD in one family (Kemp et al., 2001).
