Two novel mutations in the adrenoleukodystrophy gene in two unrelated Japanese families and the long-term effect of bone marrow transplantation.
J Neurol Sci. 2000 Aug 15;177(2):131-8., [PMID:10980309]
Abstract [show]
We identified two novel missense mutations in exon 1 of adrenoleukodystrophy (ALD) gene in two unrelated Japanese families. The first, G(874)C transition results in Arg(163)Pro substitution in the cytoplasmic domain of the ALD protein in adrenomyeloneuropathy family. The second, C(679)G results in Ser(98)Trp substitution in the first transmembrane loop in childhood onset cerebral ALD family. Both mutations cause the substitution of polar amino acid (arginine and serine) with non-polar amino acid (proline and tryptophan). Bone marrow transplantation (BMT) from his non-affected his younger sister was performed on a boy with childhood onset cerebral ALD who showed neurological deficit and brain MRI abnormalities. We evaluated the effect of BMT over a 6-year period in terms of neurological deficit, the level of very-long-chain fatty acids (VLCFA) in plasma and fibroblasts, and brain MRI. After BMT, patient's peripheral white blood cells were replaced by donor's XX ones carrying a normal ALD gene confirmed by in situ hybridization using satellite DNA of the centromere of X and Y chromosomes as probes and the level of VLCFA in lymphocytes was within normal limit. However, his neurological state progressively deteriorated. BMT was not beneficial to him.

Spectrum of mutations in the gene encoding the adrenoleukodystrophy protein.
Am J Hum Genet. 1995 Jan;56(1):44-50., [PMID:7825602]
Abstract [show]
X-linked adrenoleukodystrophy (ALD) has been associated with mutations in a gene encoding an ATP-binding transporter, which is located in the peroxisomal membrane. Deficiency of the gene leads to impaired peroxisomal beta-oxidation. Systematic analysis of the open reading frame of the ALD gene, using reverse transcriptase-PCR, followed by direct sequencing, revealed mutations in all 28 unrelated kindreds analyzed. No entire gene deletions or drastic promoter mutations were detected. In only one kindred did the mutation involve multiple exons. The other mutations were small alterations leading to missense (13 of 28) or nonsense mutations, a single amino acid deletion, frameshifts, or splice acceptor-site defects. Mutations affecting a single amino acid were concentrated in the region between the third and fourth putative transmembrane domains and in the ATP-binding domain. Mutations were detected in all investigated ALD kindreds, suggesting that this gene is the only gene responsible for X-linked ALD. This overview of mutations is useful in the determination of structurally and functionally important regions and provides an efficient screening strategy for identification of mutations in the ALD gene.
