Variability of endocrinological dysfunction in 55 patients with X-linked adrenoleucodystrophy: clinical, laboratory and genetic findings.
Eur J Endocrinol. 1997 Jul;137(1):40-7., [PMID:9242200]
Abstract [show]
X-linked adrenoleucodystrophy (ALD) has been shown to be one of the most frequent causes of Addison's disease in men. It is characterized by an impaired peroxisomal beta-oxidation of very long chain fatty acids and is associated with mutations of the ALD gene resulting in a defective peroxisomal membrane transport protein. There is a striking variability of endocrinological and neurological symptoms in patients with ALD, with no clearly evident correlation between mutations of the ALD gene and the different neurological phenotypes. No data on endocrinological symptoms and the ALD genotype have been published so far. We report endocrinological, clinical, laboratory and molecular genetic data from 55 patients with ALD from 34 families. Endocrinological symptoms of adrenal insufficiency were observed in 33 patients, 20 of whom showed additional neurological symptoms of cerebral ALD or adrenomyeloneuropathy. Isolated neurological symptoms were seen in 12 patients; in nine patients there were neither endocrinological nor neurological symptoms. Mutations of the ALD gene (n = 28) were detected in 50 patients (including nine sets of brothers) from 32 families. No correlation was found between the ALD gene mutation and endocrinological dysfunction. However, we found that all sets of brothers were concordant for the endocrinological phenotype (cortisol synthesis was reduced in two sets and normal in seven sets), whereas four sets showed a discordant neurological phenotype. As yet unknown hereditary factors other than mutations within the ALD gene may interfere with the endocrinological phenotype more strongly than with the neurological phenotype of ALD.

Abstract [show]
BACKGROUND: X-linked adrenoleukodystrophy (X-ALD) is a neurodegenerative disorder characterized by progressive demyelination of the nervous system, adrenocortical insufficiency and increase of very long chain fatty acids (VLCFAs) in the plasma and tissues. METHODS: A total of 131 individuals from 30 Chinese pedigrees were involved in this study, including 42 symptomatic patients, 44 female carriers, and 15 high-risk fetuses from 13 families. The mutation was first pinpointed through long distance RT-PCR-based RNA approach and confirmed through peripheral blood DNA approach. RESULTS: A total of 28 mutations were identified, of which 19 were missense, 3 nonsense and 6 frame-shift mutations. Thirteen mutations were novel, i.e. p.R280L, p.P580L, p.G343V, p.S108X, p.R259W, p.P534R, p.fs A246, p.L576P, p.K602X, p.A314P, p.N148D, p.H283R, and p.fs R89. Two mutations occurred de novo, for they were not found in somatic cells of their parents. Three females from the same family developed AMN-like symptoms and they were heterozygous for the p.H283R mutation. Four asymptomatic boys were diagnosed as X-ALD patients and prenatal molecular diagnosis were provided for 13 X-ALD-stricken families. CONCLUSIONS: Our work extended the spectrum of mutations in X-ALD and benefited genetic counseling through reliable identification of heterozygous females and asymptomatic males.

Abstract [show]
OBJECTIVE: To identify asymptomatic males with X-linked adrenoleukodystrophy (X-ALD) from Chinese pedigrees by molecular genetic testing. METHODS: Genomic DNA was extracted from peripheral blood of the asymptomatic individuals from X-ALD families, and fragments spanning the proband's mutation were amplified. PCR-RFLP, direct sequencing and denaturing high performance liquid chromatography (DHPLC) were used to detect the PCR products. RESULTS: Four asymptomatic male subjects from three Chinese X-ALD pedigrees were found to carry the same mutation with the probands. In Pedigree 1, by restriction analysis with endonuclease Eco47 I, the digestion pattern of the proband's elder brother (Subject 1) was same with the proband, which indicated that both carried the same mutation. In Pedigree 2 and Pedigree 3, the PCR products were analysed by DHPLC, and the patterns of elution peaks of the Subjects 2-4 and the heterozygous mothers were similar, which indicated the presence of sequence alterations in the ABCD1 gene. DNA sequencing of the corresponding PCR products confirmed the mutations. CONCLUSIONS: Molecular testing was an effective way to determine the genotype of family members of X-ALD before they develop any symptoms. Early and preferable pre-symptomatic identification of hemizygotes is of great benefit to affected individuals and their families.

Abstract [show]
Adrenoleukodystrophy (ALD) is an X-linked neurodegenerative disorder characterized by elevated very long chain fatty acid (VLCFA) levels, reduced activity of peroxisomal VLCFA-CoA ligase, and variable phenotypic expression. A putative gene for ALD was recently identified and surprisingly encodes a protein (ALDP) that belongs to a family of transmembrane transporters regulated or activated by ATP (the ABC proteins). We have examined genomic DNA from ALD probands for mutations in the putative ALD gene. We detected large deletions of the carboxyl-terminal portion of the gene in 4 of 112 probands. Twenty-five of the ALD probands whose ALD genes appeared normal by Southern blot analysis were surveyed for mutations by Single Strand Conformation Polymorphism (SSCP) procedures and DNA sequence analysis. SSCP variants were detected in 22 probands and none in 60 X-chromosomes from normal individuals. Mutations were detected in all of the ALD probands. The mutations were distributed throughout the gene and did not correlate with phenotype. Approximately half were non-recurrent missense mutations of which 64% occurred in CpG dinucleotides. There was a cluster of frameshift mutations in a small region of exon 5, including an identical AG deletion in 7 unrelated probands. These data strongly support the supposition that mutations in the putative ALD gene result in ALD.

ABCD1 gene mutations in Chinese patients with X-linked adrenoleukodystrophy.
Pediatr Neurol. 2005 Aug;33(2):114-20., [PMID:16087056]
Abstract [show]
X-linked adrenoleukodystrophy is a neurodegenerative disorder caused by mutations in the adrenoleukodystrophy (ALD) protein gene ABCD1. This study used direct sequencing of genomic polymerase chain reaction products to perform mutational analysis of ABCD1 in 34 unrelated Chinese X-linked adrenoleukodystrophy patients and 27 of their maternal relatives. Thirty-two different mutations were identified in 34 patients. Most of the mutations (62.5%, 20/32) were missense mutations, six of which are novel. One novel single nucleotide polymorphism, c.1047 C>A, was also found in three patients and their mothers, which can also be observed in 1 of 120 normal control alleles. Two synonymous mutations (p.L516L and p.V349V) appeared in two unrelated patients, and no other mutations were evident after screening the gene's 10 exons. Seventeen of the probands' mothers were found to be heterozygous for the same mutations present in their sons' ABCD1 gene. Eight of the 10 screened sisters and cousins were identified as carriers. There were no hot spot mutations in the ABCD1 gene of Chinese patients with X-linked adrenoleukodystrophy. However, over half of the mutations (19/34) were located in exon 1 and exon 6, suggesting possible hot exons. No obvious relationship between genotype and phenotype was observed.

Abstract [show]
PURPOSE: This study was designed to investigate the characteristics of Korean adrenomyeloneuropathy (AMN) patients. MATERIALS AND METHODS: We retrospectively selected 12 Korean AMN patients diagnosed by clinical analysis and increased plasma content of very long chain fatty acids. RESULTS: All 12 patients were men. Patient ages at symptom onset ranged from 18 to 55 years. Family history was positive in two patients. The phenotype distributions consisted of AMN without cerebral involvement in seven patients, AMN with cerebral involvement in two patients, and the spinocerebellar phenotype in three patients. Nerve conduction studies revealed abnormalities in four patients and visual evoked tests revealed abnormalities in three patients. Somatosensory evoked potential tests revealed central conduction defects in all of the tested patients. Spinal MRI showed diffuse cord atrophy or subtle signal changes in all 12 patients. Brain MRI findings were abnormal in six of the nine tested patients. These brain abnormalities reflected the clinical phenotypes. Mutational analysis identified nine different ABCD1 mutations in 10 of 11 tested patients. Among them, nine have been previously reported and shown to be associated with various phenotypes; one was a novel mutation. CONCLUSION: In conclusion, the present study is the first to report on the clinical and mutational spectrum of Korean AMN patients, and confirms various clinical presentations and the usefulness of brain MRI scan.
