Adrenoleukodystrophy: An X-linked recessive disorder characterized by the accumulation of saturated very long chain fatty acids in the LYSOSOMES of ADRENAL CORTEX and the white matter of CENTRAL NERVOUS SYSTEM. This disease occurs almost exclusively in the males. Clinical features include the childhood onset of ATAXIA; NEUROBEHAVIORAL MANIFESTATIONS; HYPERPIGMENTATION; ADRENAL INSUFFICIENCY; SEIZURES; MUSCLE SPASTICITY; and DEMENTIA. The slowly progressive adult form is called adrenomyeloneuropathy. The defective gene ABCD1 is located at Xq28, and encodes the adrenoleukodystrophy protein (ATP-BINDING CASSETTE TRANSPORTERS).Diffuse Cerebral Sclerosis of Schilder: A rare central nervous system demyelinating condition affecting children and young adults. Pathologic findings include a large, sharply defined, asymmetric focus of myelin destruction that may involve an entire lobe or cerebral hemisphere. The clinical course tends to be progressive and includes dementia, cortical blindness, cortical deafness, spastic hemiplegia, and pseudobulbar palsy. Concentric sclerosis of Balo is differentiated from diffuse cerebral sclerosis of Schilder by the pathologic finding of alternating bands of destruction and preservation of myelin in concentric rings. Alpers' Syndrome refers to a heterogeneous group of diseases that feature progressive cerebral deterioration and liver disease.

Adrenoleukodystrophy-related protein can compensate functionally for adrenoleukodystrophy protein deficiency (X-ALD): implications for therapy. (1/213)

Inherited defects in the peroxisomal ATP-binding cassette (ABC) transporter adrenoleukodystrophy protein (ALDP) lead to the lethal peroxisomal disorder X-linked adrenoleukodystrophy (X-ALD), for which no efficient treatment has been established so far. Three other peroxisomal ABC transporters currently are known: adrenoleukodystrophy-related protein (ALDRP), 70 kDa peroxisomal membrane protein (PMP70) and PMP70- related protein. By using transient and stable overexpression of human cDNAs encoding ALDP and its closest relative ALDRP, we could restore the impaired peroxisomal beta-oxidation in fibroblasts of X-ALD patients. The pathognomonic accumulation of very long chain fatty acids could also be prevented by overexpression of ALDRP in immortalized X-ALD cells. Immunofluorescence analysis demonstrated that the functional replacement of ALDP by ALDRP was not due to stabilization of the mutated ALDP itself. Moreover, we were able to restore the peroxisomal beta-oxidation defect in the liver of ALDP-deficient mice by stimulation of ALDRP and PMP70 gene expression through a dietary treatment with the peroxisome proliferator fenofibrate. These results suggest that a correction of the biochemical defect in X-ALD could be possible by drug-induced overexpression or ectopic expression of ALDRP.  (+info)

Retroviral-mediated adrenoleukodystrophy-related gene transfer corrects very long chain fatty acid metabolism in adrenoleukodystrophy fibroblasts: implications for therapy. (2/213)

X-linked adrenoleukodystrophy is a demyelinating disorder of the central nervous system with an impaired very long chain fatty acid metabolism. The adrenoleukodystrophy gene encodes a peroxisomal membrane protein that is part of a family of related ATP-binding transporters including the adrenoleukodystrophy-related protein. The adrenoleukodystrophy protein and adrenoleukodystrophy-related protein show 66% identity and have a mirror expression in most mouse tissues. We show that retroviral-mediated adrenoleukodystrophy-related gene transfer corrects very long chain fatty acid accumulation in adrenoleukodystrophy fibroblasts, irrespective of the presence or absence of adrenoleukodystrophy protein. Pharmacological approaches aiming at overexpressing the adrenoleukodystrophy-related gene in the central nervous system of adrenoleukodystrophy patients might thus offer new therapeutic leads.  (+info)

Beyond the disorder: one parent's reflection on genetic counselling. (3/213)

As a mother of two sons with adrenoleukodystrophy the author of this paper writes about her experiences of genetic counselling following the diagnosis. She discusses the dilemmas, emotions and aftermath this knowledge has brought to her family and the roles she played. Personal concerns are raised about the values guiding genetic counselling which, she found, focused on the technical details without considering the ethical implications arising from the new knowledge or the emotional dilemmas of prenatal testing. Some consequences of choice and the value of hope are discussed. She concludes by challenging genetic counsellors to deliver a service which not only provides technical information but is cognisant of the ethical considerations this information may foist upon a family.  (+info)

Preventing neurodegeneration in the Drosophila mutant bubblegum. (4/213)

The Drosophila melanogaster recessive mutant bubblegum (bgm) exhibits adult neurodegeneration, with marked dilation of photoreceptor axons. The bubblegum mutant shows elevated levels of very long chain fatty acids (VLCFAs), as seen in the human disease adrenoleukodystrophy (ALD). In ALD, the excess can be lowered by dietary treatment with "Lorenzo's oil," a mixture of unsaturated fatty acids. Feeding the fly mutant one of the components, glyceryl trioleate oil, blocked the accumulation of excess VLCFAs as well as development of the pathology. Mutant flies thus provide a potential model system for studying mechanisms of neurodegenerative disease and screening drugs for treatment.  (+info)

Progression of abnormalities in adrenomyeloneuropathy and neurologically asymptomatic X-linked adrenoleukodystrophy despite treatment with "Lorenzo's oil". (5/213)

OBJECTIVES: X-linked adrenoleukodystrophy (X-ALD) is an inherited disorder of peroxisomal fatty acid oxidation, biochemically characterised by the accumulation of saturated very long chain fatty acids (VLCFAs), particularly hexacosanoic acid (C26:0). Dietary treatment with a 4:1 mixture of glyceroltrioleate and glyceroltrierucate ("Lorenzo's oil") normalises plasma VLCFA concentrations, but neither ameliorates nor arrests the rapid progression of neurological symptoms in the cerebral variants of X-ALD. The efficacy of "Lorenzo's oil" in the milder phenotypes of X-ALD was assessed, as this has been much less investigated. METHODS: Twenty two patients who were treated with "Lorenzo's oil" for at least 12 months for a median period of 2.5 (range 1.0-6.0) years were studied. Two had asymptomatic ALD, four the "Addison only" variant, 13 adrenomyeloneuropathy (AMN), and three were symptomatic female carriers. RESULTS: The plasma C26:0 concentration normalised or near normalised in 19 patients (86%), in the three others it decreased significantly. Nevertheless, disability as measured with the extended disability status scale score increased mildly (0.5 (95% confidence interval (95% CI) 0.25-1.0)) in the 16 patients with neurological symptoms. Furthermore, one "Addison only" patient and one patient with AMN developed cerebral demyelination, and another "Addison only" patient developed AMN. Adrenocortical insufficiency evolved in one patient with AMN, and hypogonadism in one patient with asymptomatic ALD and two patients with AMN. Nerve conduction, evoked potential studies (SEP, BAEP, VEP), and abnormalities on cerebral MRI did not improve. On the other hand, side effects were often noted-namely, mild increases in liver enzymes (55%), thrombocytopenia (55%), gastrointestinal complaints (14%), and gingivitis (14%). We also found a mild decrease in haemoglobin concentration and leucocyte count. CONCLUSIONS: The data suggest that treatment with "Lorenzo's oil" neither improved neurological or endocrine function nor arrested progression of the disease. Furthermore, the oil often induced adverse effects. Therefore, it is advocated that "Lorenzo's oil" should not be prescribed routinely to patients with X-ALD who already have neurological deficits.  (+info)

Immunological reconstitution and correlation of circulating serum inflammatory mediators/cytokines with the incidence of acute graft-versus-host disease during the first 100 days following unrelated umbilical cord blood transplantation. (6/213)

We investigated early immunological reconstitution and the production of circulating inflammatory mediators and their relationship to aGVHD in children during the first 100 days following unrelated UCBT. Nine patients had an underlying malignant disease (ALL, ANLL), and two, non-malignant diseases (SAA, ALD). The median age was 10 years (range: 1.25-21). Seven of 11 patients were alive by day 100, two died from regimen-related toxicity, and two died from severe aGVHD (grade >/=III). Myeloid engraftment (ANC >/=500/mm3 x 2 days) occurred at a median of 24 days (range: 14-55), while platelet engraftment (platelet count >/=20 000/mm3 untransfused x 7 days) was delayed and occurred at a median of 52 days (range: 33-95). The mean cell dose of CD34+ cells was 3.3 +/- 3.51 x 10(5)/kg, and of CD34+/CD41+ cells was 3.94 +/- 3.99 x 10(4)/kg. Acute GVHD (grade II-IV) developed in seven patients (77%), and severe aGVHD (grade III-IV) developed in five patients (55%). Serum levels of IL-2Ralpha, IL-2, IL-4, IL-7, IL-12, and IFNgamma were not significantly different between patients with grades 0-I aGVHD and patients with grades II-IV aGVHD. Evaluation of immunological reconstitution on day 90 post UCBT demonstrated an early recovery of the absolute numbers of B cells (CD19+) and NK cells (CD3-/CD56+). Immunoglobulin levels for IgG, IgM and IgA remained normal throughout the study period. PMN functional studies demonstrated normal superoxide generation, bacterial killing (BK), and chemotaxis (CTX). However, both helper (CD3+/CD4+) and suppressor (CD3+/CD8+) T cell subsets remained low during the first 100 days post UCBT with mean +/- s.e.m. values of 120 +/- 29/mm3 and 10 +/- 50/mm3, respectively (normal = 900-2860/mm3 (CD3/CD4), normal = 630-1910/mm3 (CD3/CD8)). Mitogen response studies showed low blastogenesis to PHA and PWM, with a mean c.p.m. +/- s.e.m. value of 1.7 +/- 0.67 x 10(4) for PHA (NL >/= 75 x 10(3)) and 8.42 +/- 4.1 x 10(3) for PWM (NL >/=25 x 10(3)). In conclusion, serum levels of inflammatory mediators were not predictive nor did they correlate with the severity of aGVHD. Recovery of NK cells, B cells, and PMN functions occurred within the first 90 days post transplant. However, T cell subsets, CD3+/CD4+ and CD3+/CD8+, and T cell functional activity remained significantly decreased and may account for the high incidence of infectious morbidity seen during this immediate post UCBT period.  (+info)

Homo- and heterodimerization of peroxisomal ATP-binding cassette half-transporters. (7/213)

Mammalian peroxisomal proteins adrenoleukodystrophy protein (ALDP), adrenoleukodystrophy-related protein (ALDRP), and 70-kDa peroxisomal protein (PMP70) belong to the superfamily of ATP-binding cassette (ABC) transporters. Unlike many ABC transporters that are single functional proteins with two related halves, ALDP, ALDRP, and PMP70 have the structure of ABC half-transporters. The dysfunction of ALDP is responsible for X-linked adrenoleukodystrophy (X-ALD), a neurodegenerative disorder in which saturated very long-chain fatty acids accumulate because of their impaired peroxisomal beta-oxidation. No disease has so far been associated with mutations of adrenoleukodystrophy-related or PMP70 genes. It has been proposed that peroxisomal ABC transporters need to dimerize to exert import functions. Using the yeast two-hybrid system, we show that homo- as well as heterodimerization occur between the carboxyl-terminal halves of ALDP, ALDRP, and PMP70. Two X-ALD disease mutations located in the carboxyl-terminal half of ALDP affect both homo- and heterodimerization of ALDP. Co-immunoprecipitation demonstrated the homodimerization of ALDP, the heterodimerization of ALDP with PMP70 or ALDRP, and the heterodimerization of ALDRP with PMP70. These results provide the first evidence of both homo- and heterodimerization of mammalian ABC half-transporters and suggest that the loss of ALDP dimerization plays a role in X-ALD pathogenesis.  (+info)

X-linked adrenoleukodystrophy: the role of contrast-enhanced MR imaging in predicting disease progression. (8/213)

BACKGROUND AND PURPOSE: Early assignment of disease progression among patients with X-linked adrenoleukodystrophy (ALD) is critical for the appropriate selection of effective therapy. We evaluated the association between contrast enhancement on T1-weighted spin-echo MR images and disease progression. METHODS: Clinical charts of patients with X-linked ALD were reviewed for age, availability of MR images of the brain, severity of neurologic impairment, and duration and number of follow-up evaluations. Forty-three male patients with X-linked ALD had undergone multiple MR imaging examinations of the brain that consisted of at least sagittal and axial T1-weighted spin-echo, axial double-echo spin-echo, and contrast-enhanced axial T1-weighted spin-echo imaging. The MR images were reviewed for the presence of contrast enhancement. In addition, global disease burden, as shown by the double-echo spin-echo images, was assessed using a visual scoring method (Loes score). RESULTS: Enhancement was seen on the initial T1-weighted spin-echo MR images of 21 (49%) patients; 18 (86%) of the 21 patients had disease progression revealed by the follow-up evaluations based on MR imaging (Loes) and neurologic scores. No enhancement was seen on the initial T1-weighted spin-echo MR images of 22 (51%) patients; for 18 (82%) of the 22 patients, no evidence of disease progression was revealed by the follow-up evaluations. CONCLUSION: There is a very strong association between the presence of contrast enhancement on T1-weighted MR images and X-linked ALD progression based on clinical evaluation and MR imaging.  (+info)

The genetic landscape of X-linked adrenoleukodystrophy: inheritance, mutations, modifier genes, and diagnosis Christoph Wiesinger,1 Florian S Eichler,2 Johannes Berger1 1Department of Pathobiology of the Nervous System, Center for Brain Research, Medical University of Vienna, Vienna, Austria; 2Department for Neurology, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA Abstract: X-linked adrenoleukodystrophy (X-ALD) is caused by mutations in the ABCD1 gene encoding a peroxisomal ABC transporter. In this review, we compare estimates of incidence derived from different populations in order to provide an overview of the worldwide incidence of X-ALD. X-ALD presents with heterogeneous phenotypes ranging from adrenomyeloneuropathy (AMN) to inflammatory demyelinating cerebral ALD (CALD). A large number of different mutations has been described, providing a unique opportunity for analysis of functional domains within ABC transporters. Yet the molecular basis for the heterogeneity of
Mutations in the X-linked adrenoleukodystrophy (X-ALD) protein cause accumulation of unbranched saturated very-long-chain fatty acids, particularly in brain and adrenal cortex. In humans, the genetic defect causes progressive inflammatory demyelination in the brain, where very-long-chain fatty acids accumulate within phospholipid fractions such as lysophosphatidylcholine.To address mechanisms of inflammation, we studied microglial activation in human ALD (10 autopsies) and lysophosphatidylcholine (C24:0) injection into the parietal cortex of mice.Unexpectedly, we found a zone lacking microglia within perilesional white matter, immediately beyond the actively demyelinating lesion edge. Surrounding this zone we observed clusters of activated and apoptotic microglia within subcortical white matter. Lysophosphatidylcholine (C24:0) injection in mice led to widespread microglial activation and apoptosis.Our data suggest that the distinct mononuclear phagocytic cell response seen in cerebral X-ALD ...
X-linked adrenoleukodystrophy is a devastating peroxisomal disorder with only limited options for treatment. Recent findings however have pointed towards fatty acid elongation as a possible target for therapeutic intervention of X-ALD. Chapter 2 describes how bezafibrate reduces VLCFA levels in X-ALD fibroblasts by inhibiting fatty acid chain elongation. Based on these results, an open-label pilot study was performed to evaluate the effect of bezafibrate on VLCFA accumulation in blood cells of AMN patients. Unfortunately, bezafibrate failed to lower VLCFA levels in blood cells of X-ALD patients. Most likely this is attributable to its inability to reach adequate drug levels in vivo. In chapter 3 the kinetic characteristics of ELOVL1 and further investigation of the effect of fibrates on fatty acid chain elongation are described. This revealed that bezafibrate had the strongest effect in intact cells while the CoA-ester of gemfibrozil was the strongest inhibitor of VLCFA elongation activity in ...
Adrenoleukodystrophy is a genetic condition that primarily affects males and leads to problems with the adrenal glands and the nervous system. The adrenal glands function to produce hormones and are located above the kidneys. There are multiple forms of X-linked adrenoleukodystrophy that can be divided based on the symptoms that are present in any one particular patient. Childhood cerebral forms have an onset of ages 4-8 and symptoms include attention problems, poor school performance, difficulty in understanding speech, reading comprehension problems, clumsiness, and problems with eyesight. Children with this form may also have seizures and problems progress over time. The adrenomyeloneuropathy (AMN) form has symptoms often beginning in 20s-40s and symptoms include leg weakness, difficulties with digestion and sexual dysfunction that gets worse with time. Individuals with the Addison-disease-only type typically start showing symptoms in childhood that may include vomiting, weakness and changes ...
X-linked adrenoleukodystrophy (X-ALD) is the most common peroxisomal disorder. The disease is caused by mutations in the ABCD1 gene that encodes the peroxisomal membrane protein ALDP which is involved in the transmembrane transport of very long-chain fatty acids (VLCFA; ≥C22). A defect in ALDP results in elevated levels of VLCFA in plasma and tissues. The clinical spectrum in males with X-ALD ranges from isolated adrenocortical insufficiency and slowly progressive myelopathy to devastating cerebral demyelination. The majority of heterozygous females will develop symptoms by the age of 60 years. In individual patients the disease course remains unpredictable. This review focuses on the diagnosis and management of patients with X-ALD and provides a guideline for clinicians that encounter patients with this highly complex disorder.
X-linked adrenoleukodystrophy (X-ALD), a [sex-linked] progressive neurodegenerative disease, is caused by a defect in the ABCD1 gene. The disease is expressed in multiple ways, but the most common adult form is adrenomyeloneuropathy (AMN), which results in slowly progressive changes in muscle tone and weakness, sensory loss, and dysfunction of the autonomic nervous system. In a previous study the investigators linked abnormalities in the [brain/spinal cord] to lower extremity weakness in men with AMN; however, there have been no studies evaluating these relationships in women carriers (i.e., women with AMN). It is unknown, in women with AMN, how the pattern of damage in the brain and spinal cord relates to disability and if these patterns predict responsiveness to treatment. The investigators hypothesize that by using magnetization transfer (MT) and diffusion tensor imaging (DTI), two magnetic resonance imaging (MRI) modalities, to track particular changes in the brain and spinal cord will ...

Stem cell-transplantation therapy for adrenoleukodystrophy: current perspectives Weston Miller Department of Pediatrics, Division of Blood and Marrow Transplantation, University of Minnesota, Minneapolis, MN, USA Abstract: Adrenoleukodystrophy (ALD) is a rare, X-linked peroxisomal disorder of impaired very long-chain fatty-acid metabolism. It results from various mutations in the ABCD1 gene (Xq28). All males with the biochemical defect of ALD are at risk of developing cerebral white-matter disease (cALD) during their lifetime. Thirty-five percent of ALD patients develop cALD in boyhood, a life-threatening phenotype characterized by rapidly expanding, neuroinflammatory demyelination and irreversible clinical neurologic decline. The ABCD1 genotype does not predict susceptibility to or protection from the childhood cALD phenotype; therefore, clinicians must remain ever vigilant for its development when monitoring ALD patients.

X-linked adrenoleukodystrophy (X-ALD) is a rare genetic condition caused by mutations in the ABCD1 gene that result in accumulation of very long chain fatty acids (VLCFAs) in various tissues. This leads to demyelination in the CNS and impaired steroidogenesis in the adrenal cortex and testes. A 57-year-old gentleman was referred for the assessment of bilateral gynaecomastia of 6 months duration. He had skin hyperpigmentation since 4 years of age and spastic paraparesis for the past 15 years. Physical examination findings included generalised hyperpigmentation (including skin, buccal mucosa and palmar creases), blood pressure of 90/60 mmHg, non-tender gynaecomastia and bilateral hypoplastic testes. Lower limb findings were those of a profoundly ataxic gait associated with significant paraparesis and sensory loss. Primary adrenal insufficiency was confirmed and investigations for gynaecomastia revealed normal testosterone with mildly elevated luteinising hormone level and normal prolactin. The ...

Adrenoleukodystrophy or ALD is an inborn error of the fat metabolism, which causes the accumulation of very long chain fatty acids (C26)in nearly all tissues in the body, especially in the brain and myelin sheath. In the severe childhood form of X-ALD (since it is linked to the X- Chromosome) inflammatory processes in the CNS take place thereby demyelineating nervous tissue leading to rapid deterioration and early death. In the aduld form - called Adrenomyeloneuropathy (AMN) there seems to be only demyelineation in the spine, leading to ataxia. Often misdiagnosed as Multiple Sclerosis! The Lorenzos Oil is a mixture of oleic acid and erucic acid and both are capable of normalizing the often drastically increased values of C26 in the blood. This is part of a diet which restricts ...
Leukodystrophies compass a wide range of genetic disorders that compromise the white matter. Some of them exhibit different phenotypes with late and slow onset. The present work reports an unusual case of probable X-Linked Adrenoleukodystrophy that could be classified in adrenomyeloneupathy, but there were no signs of adrenal insufficiency and the cognitive decline developed fast. MRI evinced classical symmetrical parieto-occipital pattern of lesion, although dosage of very long chain fatty acids was normal.
CAMBRIDGE, Mass. - bluebird bio, Inc. (Nasdaq: BLUE), a clinical-stage company committed to developing potentially transformative gene therapies for severe genetic diseases and T cell-based immunotherapies for cancer, today announced that interim data from the ongoing Phase 2/3 Starbeam Study (ALD-102) for the treatment of cerebral adrenoleukodystrophy (CALD) will be presented in an oral presentation during the Clinical Trials plenary session on April 20, 2016 at the American Academy of Neurology (AAN) 2016 Annual Meeting. The meeting is being held April 15 - 21, 2016 in Vancouver, BC, Canada.. "The childhood form of cerebral adrenoleukodystrophy is a devastating neurodegenerative genetic disease that affects boys and is generally fatal if left untreated. Allogeneic hematopoietic stem cell transplant (allo-HSCT) is currently the only available effective therapy, but is potentially associated with serious safety risks, including graft rejection, graft-versus-host disease and transplant-related ...
... (ALD) is one of a group of genetic disorders called the leukodystrophies that cause damage to the myelin sheath, an insulating membrane that surrounds nerve cells in the brain. People with ALD accumulate high levels of saturated, very long chain fatty acids (VLCFA) in the brain and adrenal cortex because they do not produce the enzyme that breaks down these fatty acids in the normal manner. The loss of myelin and the progressive dysfunction of the adrenal gland are the primary characteristics of ALD. ALD has two subtypes. The most common is the X-linked form (X-ALD), which involves an abnormal gene located on the X-chromosome. Women have two X-chromosomes and are the carriers of the disease, but since men only have one X-chromosome and lack the protective effect of the extra X-chromosome, they are more severely affected. Onset of X-ALD can occur in childhood or in adulthood. The childhood form is the most severe, with onset between ages 4 and 10. The most common symptoms are ...

Subjects will have a screening visit within 6 weeks prior to the Baseline visit. At Baseline visit blood will be drawn and to establish baseline values for plasma and red blood cell (RBC) very long chain fatty acids (VLCFA; C22, C24, and C26). Subjects will receive an oral dose of 50 mcg sobetirome once daily for 14 days beginning on Day 1. Subjects will be kept in the clinic on Day 1 for 16 hours following their initial dose of sobetirome for repeat blood sampling for pharmacokinetic analysis. Subjects will return to the clinic on days 7, 15, 21 and 28 for blood collection for VLCFA measurements. On day 15, after safety assessment, subjects will receive an increased dose of 100 mcg and this dose will be continued once daily through Day 28. Subjects will continue to return to the clinic weekly for blood and urine collection and safety assessments. Subjects will return to the clinic on day 42 for an End of Study visit that will involve a final measurement of VLCFA and blood and urine safety labs ...
Also known as Lorenzos Oil disease, adrenoleukodystrophy (ALD) is estimated to affect one in every 21,000 male births worldwide. The cerebral form of the disease, cerebral adrenoleukodystrophy (CALD), is a potentially fatal form of ALD. CALD involves a breakdown of the protective sheath of the nerve cells in the brain that are responsible for thinking and muscle control.. Currently, the only effective treatment option for patients with CALD is allogeneic hematopoietic stem cell transplant (HSCT). Potential complications of allogeneic HSCT, which can be fatal, include graft failure, graft versus host disease (GVHD) and opportunistic infections, particularly in patients who undergo allogeneic HSCT using cells from a donor who is not a matched, unaffected sibling.. Early diagnosis of CALD is important, as the outcome of HSCT varies with clinical stage of the disease at the time of transplant. Favorable outcomes have been observed in patients who undergo transplant in the early stages of cerebral ...
The prevalence of alpha-thalassaemias is up to 5% in Hong Kong and up to 40% in some parts of South East Asia. Haemoglobin H consists of four betaglobin chains. Instead of the usual complement of four normal alphaglobin genes (two on each chromosome 16), people with haemoglobin H disease have only one. At the other three alphaglobin gene sites, they have either three deletions or two deletions and one mutation. Now, work in Hong Kong (New England Journal of Medicine2000;343:544-50) has shown that those with a mutation have more severe disease but iron overload is equally a problem in both types.. Eight of 13 American and four of five French boys with cerebral X-linked adrenoleukodystrophy survived bone marrow transplantation at ages 5 to 11 years and were followed for five to ten years (Lancet2000;356:713-18). Verbal intelligence remained normal in 11 and non-verbal abilities remained stable or improved in seven. Eight showed continuing demyelination on magnetic resonance imaging (MRI) but later ...

The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the ALD subfamily, which is involved in peroxisomal import of fatty acids and/or fatty acyl-CoAs in the organelle. All known peroxisomal ABC transporters are half transporters which require a partner half transporter molecule to form a functional homodimeric or heterodimeric transporter. This peroxisomal membrane protein is likely involved in the peroxisomal transport or catabolism of very long chain fatty acids. Defects in the human gene have been identified as the underlying cause of adrenoleukodystrophy, an X-chromosome recessively inherited demyelinating disorder of the nervous system.

X-linked adrenoleukodystrophy (X-ALD), caused by a mutation in ABCD1, leads to an accumulation of long-chain fatty acids. However, the mechanism by which this accumulation causes disease is not yet understood. One of the potential factors thought to contribute to disease is oxidative stress and subsequent free-radical damage. Petrillo et al (Molecular Genetics and Metabolism, 109 (4): 366-370) offers further evidence […]. ...
X-linked adrenoleukodystrophy (ALD) is a rare neurologic disease caused by a defect in a gene required for normal ABCD1 transporter function. The lack of this function leads to progressive demyelination, severe neurologic disease and death in males, often in childhood. ALD disease progression can be controlled by allogeneic hematopoietic cell transplantation (HCT) in those patients for whom bone marrow donors can be found. This unusual correction occurs because bone marrow-derived monocyte-macrophages are known to migrate into the central nervous system and form functional microglial cells. These corrected microglial cells provide the patients with cells with normal ABCD1 transporter activity and allow normal myelin function.. Two patients with progressive ALD with no available allogeneic HCT donors were recently treated by lentiviral-mediated gene therapy. A lentiviral vector containing the normal ABCD1 transporter gene coding sequence was integrated into the patients own marrow derived ...

A 60-year-old man presented with an ataxic and spastic gait with paraparesis, having reported a tick bite. Brain MRI depicted bilateral corticospinal tract hyperintensities (figure). He had a mild lymphocytic meningitis (12 leukocytes/mm3, proteinorachia 1.48 g/L). ELISA was positive for Lyme disease in serum (immunoglobulin G [IgG] 176 UI and immunoglobulin M ,4 UI) and CSF (IgG 300 UI) with an intrathecal synthesis (index of CSF/serum-specific antibodies equal to 16 using ELISA [normal value ,1.5]). Western blot was positive for Lyme-specific antibodies in serum (18, 22, 32, 41, 60, and 75 kDa) and CSF (41 and 60 kDa). Syphilis serology was negative. After treatment (IV ceftriaxone 2 g daily for 4 weeks), gait improved and brain MRI was normal. This MRI pattern has been previously reported in amyotrophic lateral sclerosis1 and in metabolic diseases (Krabbe disease,2 X-linked adrenoleukodystrophy, cerebrotendinous xanthomatosis) or infectious diseases (human T-cell lymphotropic virus 1). ...
EVOVL4 is highly expressed in the human retina and was initially discovered as the causal gene of STGD3 [13]. Consistently, mutant mice carrying the dominant negative form of human ELOVL4 gene that was either introduced through a knock-in approach (Elovl4+/del), or transgenic approach (IRBP-ELOVL4) developed early onset of progressive photoreceptor degeneration ([18,19], Li and Deng unpublished data). In contrast, mice heterozygous for a conventional knockout of ELOVL4 developed normally and exhibited no symptoms mimicking human STGD3 [21]. Furthermore, Elovl4-/- mice died unexpected shortly after birth, suggesting that ELOVL4 may play additional functions in other organs/tissues that are critical for early postnatal survival. In addition to the eye, ELOVL4 is also presented at high levels in the skin and brain [12]. Our analysis of Elovl4-/- mice revealing the abnormal differentiation of keratinocytes, and malformation of the SC of the skin indicate that ELOVL4 indeed have critical functions in ...

X-linked dominant disorders are caused by mutations in genes on the X chromosome. Only a few disorders have this inheritance pattern, with a prime example being X-linked hypophosphatemic rickets. Males and females are both affected in these disorders, with males typically being more severely affected than females. Some X-linked dominant conditions, such as Rett syndrome, incontinentia pigmenti type 2, and Aicardi syndrome, are usually fatal in males either in utero or shortly after birth, and are therefore predominantly seen in females. Exceptions to this finding are extremely rare cases in which boys with Klinefelter syndrome (47,XXY) also inherit an X-linked dominant condition and exhibit symptoms more similar to those of a female in terms of disease severity. The chance of passing on an X-linked dominant disorder differs between men and women. The sons of a man with an X-linked dominant disorder will all be unaffected (since they receive their father's Y chromosome), and his daughters will ...
