A novel mutation in the ABCD1 gene of a Moroccan patient with X-linked adrenoleukodystrophy: case report.

ABSTRACT: X-linked adrenoleukodystrophy (X-ALD; OMIM: 300100) is the most common peroxisomal disease caused by mutations in the ATP-binding cassette, sub-family D member 1 gene or ABCD1 (geneID: 215), the coding gene for the adrenoleukodystrophy protein (ALDP), which is an ATP-binding transport protein associated to an active transport of very long chain fatty acids (VLCFAs). Dysfunction of ALDP induces an accumulation of VLCFAs in all tissues leading to a neurodegenerative disorder that involves the nervous system white matter.In our case report, magnetic resonance imaging (MRI) as well as the high levels of VLCFAs prompted the diagnosis the X-ALD. Molecular analysis of ABCD1 gene have shown a pathogenic homozygous nonsense mutation (c.1677C?>?G; p.(Tyr559*)) in exon 7.Thus, we identified here a novel mutation in the ABCD1 gene in a Moroccan patient causing X-linked adrenoleukodystrophy.

Novel ABCD1 Gene Mutation in a Korean Patient with X-Linked Adrenoleukodystrophy Presenting with Addison's Disease.

Project description:X-linked adrenoleukodystrophy (X-ALD) occurs due to mutations in the ABCD1 gene that encodes the peroxisomal membrane protein peroxisomal transporter ATP-binding cassette sub-family D member 1 (ABCD1). Degradation of very long-chain fatty acids in peroxisomes is impaired owing to ABCD dysfunction, subsequently leading to adrenomyeloneuropathy, cerebral adrenoleukodystrophy, and adrenal insufficiency. X-ALD frequently induces idiopathic Addison's disease in young male patients. Here, we confirmed the diagnosis of X-ALD in a young male patient with primary adrenal insufficiency, and identified a novel ABCD1 gene mutation (p.Trp664*, c.1991 G>A).

S149R, a novel mutation in the ABCD1 gene causing X-linked adrenoleukodystrophy.

Project description:X-linked adrenoleukodystrophy (X-ALD) is the most common peroxisomal disorder. It is a heterogeneous disorder caused by mutations in the ATP-binding cassette protein subfamily D1 (ABCD1) gene, encoding the peroxisomal membrane protein ALDP, which is involved in the transmembrane transport of very long-chain fatty acids. For the first time, we report a case of olivopontocerebellar X-ALD on the Chinese mainland. In this study, a novel mutation (c.447T>A; p.S149R) in ABCD1 was detected in a patient diagnosed with X-ALD. The mutant amino acid is well conserved among species. Bioinformatics analysis predicted the substitution to be deleterious and to cause structural changes in the adrenoleukodystrophy protein. Immunofluorescence showed an altered subcellular localization of the S149R mutant protein, which may lead to defects in the degradation of very long chain fatty acids in peroxisomes. We therefore suggest that the novel mutation, which alters ALDP structure, subcellular distribution and function, is responsible for X-ALD.

A Novel Double Mutation in the ABCD1 Gene in a Patient with X-linked Adrenoleukodystrophy: Analysis of the Stability and Function of the Mutant ABCD1 Protein.

Project description:We diagnosed an adrenomyeloneuropathy (AMN) patient with a double novel missense mutation, c.284C>A (p.A95D) and c.290A>T (p.H97L) in a single ABCD1 allele. In skin fibroblasts from the patient, no ABCD1 protein was detected by immunoblot analysis, and the C24:0 ?-oxidation activity was decreased to a level at which the ABCD1 protein was absent. To determine the responsible gene mutation in the patient, we constructed three kinds of mutated ABCD1 gene expression vectors (c.284C>A, c.290A>T or c.284C>A/c.290A>T) and transfected them into CHO cells stably expressing GFP-SKL (CHO/GFP-SKL cells) or CADDS fibroblasts lacking the ABCD1 gene. ABCD1 (p.H97L) displayed the correct peroxisomal localization in CHO/GFP-SKL cells, but ABCD1 (p.A95D) and ABCD1 (p.A95D/p.H97L) were diffuse in the cytosol. Furthermore, ABCD1 (p.H97L) was detected by immunoblot analysis and restored the C24:0 ?-oxidation activity in the CADDS fibroblasts, as the wild type ABCD1 did. On the other hand, ABCD1 (p.A95D) and ABCD1 (p.A95D/p.H97L) were not detected and the C24:0 ?-oxidation activity was not restored. These results clearly show that c.284C>A is the responsible gene mutation, whereas c.290A>T is a novel polymorphism.

A novel frameshift mutation in the XPC gene in a Moroccan patient: a case report.

Project description:Xeroderma pigmentosum is an autosomal recessive inherited disease. The diagnosis is essentially based on clinical findings and the family history. This genodermatosis is genetically heterogeneous; to date, nine genes have been associated to this disorder. Based on the result of many studies, xeroderma pigmentosum complementation group C is the most common form of xeroderma pigmentosum. A founder mutation in the XPC gene was reported in the Maghreb region of northern Africa. According to these findings, the Department of Medical Genetics in Rabat offers molecular diagnosis by screening for the recurrent mutation c.1643_1644delTG which represents 74% of all the probands with xeroderma pigmentosum.We describe the case of a 21-year-old Moroccan son of consanguineous parents diagnosed with xeroderma pigmentosum on the basis of sun-exposed skin abnormalities and bilateral ocular involvement. A molecular study led to the identification of a new frameshift insertion of four nucleotides in exon 9.To the best of our knowledge, this mutation has not been described. The sequencing of the ninth exon should be proposed as first line molecular analysis for all Moroccan patients with xeroderma pigmentosum.

Report of the First Clinical Case of a Moroccan Kabuki Patient with a Novel MLL2 Mutation.

Project description:Kabuki syndrome (also known as Niikawa-Kuroki syndrome) is a rare autosomal disorder, characterized by an unusual face, short stature, skeletal, visceral and dermatoglyphic abnormalities, cardiac anomalies, mental retardation, and immunological defects. Point mutations and large intragenic deletions and duplications of the mixed lineage leukemia 2 (MLL2) and exons deletions of lysine demethylase 6A (-KDM6A) genes have been identified as its underlying causes. We report on the first description of a Moroccan Kabuki syndrome patient with typical facial features, developmental delay, finger pads, and other anomalies carrying a novel splice site mutation in the MLL2 gene that produces a truncated and likely pathogenetic form of MLL2 protein.

Stability of the ABCD1 Protein with a Missense Mutation: A Novel Approach to Finding Therapeutic Compounds for X-Linked Adrenoleukodystrophy.

Project description:Mutations in the ABCD1 gene that encodes peroxisomal ABCD1 protein cause X-linked adrenoleukodystrophy (X-ALD), a rare neurodegenerative disorder. More than 70% of the patient fibroblasts with this missense mutation display either a lack or reduction of the ABCD1 protein because of posttranslational degradation. In this study, we analyzed the stability of the missense mutant ABCD1 proteins (p.A616T, p.R617H, and p.R660W) in X-ALD fibroblasts and found that the mutant ABCD1 protein p.A616T has the capacity to recover its function by incubating at low temperature. In the case of such a mutation, chemical compounds that stabilize mutant ABCD1 proteins could be therapeutic candidates. Here, we prepared CHO cell lines stably expressing ABCD1 proteins with a missense mutation in fusion with green fluorescent protein (GFP) at the C-terminal. The stability of each mutant ABCD1-GFP in CHO cells was similar to the corresponding mutant ABCD1 protein in X-ALD fibroblasts. Furthermore, it is of interest that the GFP at the C-terminal was degraded together with the mutant ABCD1 protein. These findings prompted us to use CHO cells expressing mutant ABCD1-GFP for a screening of chemical compounds that can stabilize the mutant ABCD1 protein. We established a fluorescence-based assay method for the screening of chemical libraries in an effort to find compounds that stabilize mutant ABCD1 proteins. The work presented here provides a novel approach to finding therapeutic compounds for X-ALD patients with missense mutations.

Role of ALDP (ABCD1) and mitochondria in X-linked adrenoleukodystrophy.

Project description:Peroxisomal disorders have been associated with malfunction of peroxisomal metabolic pathways, but the pathogenesis of these disorders is largely unknown. X-linked adrenoleukodystrophy (X-ALD) is associated with elevated levels of very-long-chain fatty acids (VLCFA; C(>22:0)) that have been attributed to reduced peroxisomal VLCFA beta-oxidation activity. Previously, our laboratory and others have reported elevated VLCFA levels and reduced peroxisomal VLCFA beta-oxidation in human and mouse X-ALD fibroblasts. In this study, we found normal levels of peroxisomal VLCFA beta-oxidation in tissues from ALD mice with elevated VLCFA levels. Treatment of ALD mice with pharmacological agents resulted in decreased VLCFA levels without a change in VLCFA beta-oxidation activity. These data indicate that ALDP does not determine the rate of VLCFA beta-oxidation and that VLCFA levels are not determined by the rate of VLCFA beta-oxidation. The rate of peroxisomal VLCFA beta-oxidation in human and mouse fibroblasts in vitro is affected by the rate of mitochondrial long-chain fatty acid beta-oxidation. We hypothesize that ALDP facilitates the interaction between peroxisomes and mitochondria, resulting, when ALDP is deficient in X-ALD, in increased VLCFA accumulation despite normal peroxisomal VLCFA beta-oxidation in ALD mouse tissues. In support of this hypothesis, mitochondrial structural abnormalities were observed in adrenal cortical cells of ALD mice.

X-linked adrenoleukodystrophy: molecular and functional analysis of the ABCD1 gene in Argentinean patients.

Project description:X-linked adrenoleukodystrophy (X-ALD) is an inherited metabolic disease associated with mutations in the ABCD1 gene that encodes an ATP-binding cassette transporter protein, ALDP. The disease is characterized by increased concentrations of very long-chain fatty acids (VLCFAs) in plasma and in adrenal, testicular and nervous tissues, due to a defect in peroxisomal VLCFA ?-oxidation. In the present study, we analyzed 10 male patients and 17 female carriers from 10 unrelated pedigrees with X-ALD from Argentina. By sequencing the ABCD1 we detected 9 different mutations, 8 of which were novel. These new mutations were verified by a combination of methods that included both functional (western blot and peroxisomal VLCFA ?-oxidation) and bioinformatics analysis. The spectrum of novel mutations consists of 3 frameshift (p.Ser284fs*16, p.Glu380Argfs*21 and p.Thr254Argfs*82); a deletion (p.Ser572_Asp575del); a splicing mutation (c.1081+5G>C) and 3 missense mutations (p.Ala341Asp, p.His420Pro and p.Tyr547Cys). In one patient 2 changes were found: a known missense (p.His669Arg) and an unpublished amino acid substitution (p.Ala19Ser). In vitro studies suggest that p.Ala19Ser is a polymorphism. Moreover, we identified two novel intronic polymorphisms and two amino acid polymorphisms. In conclusion, this study extends the spectrum of mutation in X-ALD and facilitates the identification of heterozygous females.

Bladder and Bowel Dysfunction Is Common in Both Men and Women with Mutation of the ABCD1 Gene for X-Linked Adrenoleukodystrophy.

Project description:BACKGROUND:X-linked adrenoleukodystrophy (X-ALD) is a disorder caused by mutations in the ABCD1 gene. The commonest phenotype of X-ALD is adrenomyeloneuropathy (AMN), which is characterised by involvement of the spinal cord and peripheral nerves. The aim of this study was to evaluate bladder and bowel symptoms in men with AMN and female X-ALD carriers. METHODS:In this cross-sectional study, patients with confirmed mutation of the ABCD1 gene attending a tertiary care service were approached about bladder and bowel complaints and completed the Urinary Symptom Profile (USP), Qualiveen Short Form (SF-Qualiveen), International Prostate Symptom Score (IPSS) and Neurogenic Bowel Dysfunction (NBD) questionnaires. Neurological disability was assessed using the Expanded Disability Status Scale (EDSS). RESULTS:Forty-eight patients participated, 19 males (mean EDSS score (n?=?16) 5.0 (95% CI?±?1.03)) and 29 females (mean EDSS score (n?=?25) 3.2 (95% CI?±?0.98)). Overactive bladder (OAB) symptoms were reported in both males (100%, n?=?19) and females (86.2%, n?=?25). There was no significant gender difference in severity of OAB symptoms (P?=?0.35) and impact on quality of life (P?=?0.13). Furthermore, there was no significant difference in OAB severity when symptoms were compared between female carriers and a cohort of women (n?=?17) with spinal cord damage due to multiple sclerosis (P?=?0.27). Twenty-one percent (n?=?4) of males and 10% (n?=?3) of females had moderate to severe bowel dysfunction. CONCLUSIONS:Bladder and bowel complaints are common in both men with AMN and female carriers. They have a significant impact on the quality of life yet are under-reported and under-treated. Though having an X-linked pattern of inheritance, female carriers may experience overactive bladder symptoms which are as severe as in male patients and are likely to be neurological in origin.

Contiguous deletion of the X-linked adrenoleukodystrophy gene (ABCD1) and DXS1357E: a novel neonatal phenotype similar to peroxisomal biogenesis disorders.

Project description:X-linked adrenoleukodystrophy (X-ALD) results from mutations in ABCD1. ABCD1 resides on Xq28 and encodes an integral peroxisomal membrane protein (ALD protein [ALDP]) that is of unknown function and that belongs to the ATP-binding cassette-transporter superfamily. Individuals with ABCD1 mutations accumulate very-long-chain fatty acids (VLCFA) (carbon length >22). Childhood cerebral X-ALD is the most devastating form of the disease. These children have the earliest onset (age 7.2 +/- 1.7 years) among the clinical phenotypes for ABCD1 mutations, but onset does not occur at <3 years of age. Individuals with either peroxisomal biogenesis disorders (PBD) or single-enzyme deficiencies (SED) in the peroxisomal beta-oxidation pathway--disorders such as acyl CoA oxidase deficiency and bifunctional protein deficiency--also accumulate VLCFA, but they present during the neonatal period. Until now, it has been possible to distinguish unequivocally between individuals with these autosomal recessively inherited syndromes and individuals with ABCD1 mutations, on the basis of the clinical presentation and measurement of other biochemical markers. We have identified three newborn boys who had clinical symptoms and initial biochemical results consistent with PBD or SED. In further study, however, we showed that they lacked ALDP, and we identified deletions that extended into the promoter region of ABCD1 and the neighboring gene, DXS1357E. Mutations in DXS1357E and the ABCD1 promoter region have not been described previously. We propose that the term "contiguous ABCD1 DXS1357E deletion syndrome" (CADDS) be used to identify this new contiguous-gene syndrome. The three patients with CADDS who are described here have important implications for genetic counseling, because individuals with CADDS may previously have been misdiagnosed as having an autosomal recessive PBD or SED
