X‐linked adrenoleukodystrophy is an important cause of Addison's disease in boys, but less is known about its contribution to Addison's disease in adult men. After surveying all known cases of X‐linked adrenoleukodystrophy
X-linked adrenoleukodystrophy (ALD) is a rare peroxisomal disorder that affects the white matter of the CNS, adrenal cortex, and testes (1–3). The genetic defect responsible for X-linked ALD is located in Xq28, the terminal segment of the long arm of the X chromosome . This gene normally encodes for a peroxisomal membrane protein called ALD-P. X-Linked Adrenoleukodystrophy (X-ALD) In Connecticut SB 465 was proposed in January 2013: An Act Requiring Newborn Screening for Adrenoleukodystrophy Public Act 13-242 Approved on July 2, 2013 with additional language to allow for development and validation of reliable methodology or an FDA cleared kit Van Geel et al in this issue (pp290–9)1 provide a thorough multidisciplinary analysis of the clinical progression of 22 patients with X-linked adrenoleukodystrophy (X-ALD) who were treated with Lorenzo’s oil (a 4:1 mixture of glyceryl trioleate and glyceryl trierucate). Four patients remained unchanged. One patient improved, 13 worsened, and in five some indices improved and others worsened. The plasma concentration of very long chain fatty acids is elevated in more than 99% of males with X linked adrenoleukodystrophy of all ages, irrespective of symptoms, and is valuable in establishing carrier status and prenatal diagnosis.

Adrenoleukodystrophy (ALD) is a disease linked to the X chromosome.It is a result of fatty acid buildup caused by the relevant enzymes not functioning properly, which then causes damage to the myelin sheath of the nerves, resulting in seizures and hyperactivity. Other symptoms include problems with speaking, listening, and understanding verbal instructions.
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… X-linked agammaglobulinemia (XLA) is a rare genetic disorder discovered in 1952 that affects the body's ability to fight infection. X-linked inheritance means that the gene causing the trait or the disorder is located on the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome.
X-linked adrenoleukodystrophy is a genetic neurodegenerative disorder that is characterized biochemically by abnormal accumulation of very long chain fatty acids in all tissues of the body. In
The childhood cerebral form manifests most commonly between ages four and eight years. It initially resembles attention deficit disorder or hyperactivity; progressive impairment of cognition, behavior, vision, hearing, and motor function follow the initial symptoms and often lead to total disability within two years. X-linked adrenoleukodystrophy is an inherited metabolic peroxisomal disorder and one of the more common leukodystrophies in both children and adults. It is characterized by a lack of oxidation of very long chain fatty acids (VLCFAs) that results in severe inflammatory demyelination typically of the periventricular deep white matter with posterior-predominant pattern and early involvement of Allogeneic hematopoietic stem cell transplantation (HSCT) is the only treatment that enhances survival and stabilizes neurologic symptoms in X-linked adrenoleukodystrophy (X-ALD) with cerebral Newborn screening and gene therapy are exciting new advances in the field of metabolic neurodegenerative disorders. This Viewpoint discusses X-linked adrenoleukodystrophy (ALD), an inherited disorder affecting the adrenals and nervous system white matter.

X‐linked adrenoleukodystrophy (X‐ALD) is the most common inherited peroxisomal disorder characterized by a progressive demyelination of the central nervous system. The marked loss of myelin and oligodendrocytes observed in the disease Objective: To report a case of a 19-year-old man with adrenal insufficiency due to adrenoleukodystrophy. Method: Case report and literature review. Result: A previously healthy 19-year-old male patient was admitted to the emergency room with nausea and vomiting for 5 days, who progressed to abdominal pain, severe asthenia, and fever (38.5°C). E Shapiro and colleagues (Aug 26, p 713)1 present long-term follow-up of 12 selected patients with bone marrow transplantation for childhood-onset cerebral X-linked adrenoleukodystrophy (X-ALD). They use four severity classifications: no cerebral disease, slowly progressive cerebral disease, stable cerebral disease, and advanced cerebral disease.

Mohr–Tranebjærg syndrome (MTS) is a rare X-linked recessive syndrome also known as deafness–dystonia syndrome and caused by mutation in the TIMM8A gene. All males possessing an X-linked recessive mutation will be affected, since males have only a single X chromosome and therefore have only one copy of X-linked genes. Danon disease (or glycogen storage disease Type IIb) is a metabolic disorder. Danon disease is an X-linked lysosomal and glycogen storage disorder associated with hypertrophic cardiomyopathy, skeletal muscle weakness, and intellectual… Zellweger syndrome is one of three peroxisome biogenesis disorders which belong to the Zellweger spectrum of peroxisome biogenesis disorders (PBD-ZSD). The other two disorders are neonatal adrenoleukodystrophy (NALD), and infantile Refsum… This is a list of diseases starting with the letter "X".
