X-linked adrenoleukodystrophy (X-ALD) is a rare genetic disorder that affects the nervous system and adrenal glands. It is caused by mutations in the ABCD1 gene, which leads to the accumulation of very long-chain fatty acids in the body. X-ALD primarily affects males, although some females can also be affected.
Diagnosis of X-ALD can be challenging, as symptoms may not appear until later in life. Common symptoms include progressive neurological deterioration, intellectual decline, and adrenal insufficiency. The severity and age of onset can vary widely, even within the same family. In some cases, X-ALD may present as adrenomyeloneuropathy, a milder form of the disease that typically appears in adulthood.
Clinical diagnosis of X-ALD is confirmed through genetic testing, which looks for mutations in the ABCD1 gene. This testing can also be used for carrier testing in females and prenatal testing in families with a known mutation. Additional testing may include brain imaging, hormone testing, and neurological evaluations.
Treatment for X-ALD is primarily focused on managing symptoms and preventing complications. This may include hormone replacement therapy, physical therapy, and medications to manage symptoms such as seizures or pain. Stem cell transplantation may be considered in certain cases, although the benefits and risks should be carefully evaluated.
Research and scientific studies on X-ALD are ongoing. The aims include understanding the genetic and biochemical basis of the disease, developing new treatment approaches, and improving diagnostic methods. Organizations such as the X-ALD Foundation provide support, information, and advocacy for individuals and families affected by X-ALD.

Frequency
X-linked adrenoleukodystrophy (ALD) is a rare genetic disorder that primarily affects males. It is estimated that this condition occurs in about 1 in 17,000 individuals worldwide.
ALD belongs to a group of genetic diseases known as peroxisomal disorders, which are characterized by the accumulation of very long-chain fatty acids in various tissues of the body. ALD specifically affects the adrenal glands and the white matter of the brain, leading to progressive neurological dysfunction and adrenal insufficiency.
While ALD is more common in males, females can also be affected. However, the symptoms and severity of the disease can vary significantly between individuals. In some cases, females with ALD may display milder symptoms or remain symptom-free throughout their lives.
The actual frequency of X-linked adrenoleukodystrophy may be higher than reported, as it can often go undiagnosed or misdiagnosed. Early diagnosis and treatment are crucial for better outcomes.
Research and clinical trials are ongoing to further understand the frequency, genetic causes, and underlying mechanisms of ALD. Additional information and resources can be found on websites such as PubMed, OMIM, and ClinicalTrials.gov. The ALD database and the ALD gene catalog provide further information on the frequency and types of genetic mutations associated with ALD and adrenomyeloneuropathy (AMN).
For individuals and families affected by X-linked adrenoleukodystrophy, support and advocacy groups like the Aubourg Foundation and ALD Connect offer resources, information, and assistance in coping with the condition.
Causes
The main cause of X-linked adrenoleukodystrophy (X-ALD) is a genetic mutation that affects the ABCD1 gene located on the X chromosome. This gene provides instructions for making a protein called ALDP, which is necessary for the breakdown and transportation of very long-chain fatty acids (VLCFAs) in cells.
Individuals with X-ALD inherit a copy of the mutated ABCD1 gene from their mother, who is typically an unaffected carrier, as the condition primarily affects males. Females can also be affected, but the signs and symptoms tend to be milder due to random inactivation of one X chromosome in each cell. X-ALD is classified as an X-linked condition because the ABCD1 gene is located on the X chromosome.
In X-ALD, the genetic mutation leads to impaired function of ALDP protein, resulting in the accumulation of VLCFAs in various tissues, including the brain, adrenal glands, and spinal cord. As VLCFAs build up, they cause damage to the myelin sheath, a protective covering surrounding nerve fibers in the brain and spinal cord. This damage disrupts the normal functioning of the nervous system, leading to the various symptoms associated with X-ALD.
The frequency of X-ALD is estimated to be approximately 1 in 20,000 individuals. Genetic testing is available to confirm a diagnosis of X-ALD and to identify the specific mutations in the ABCD1 gene associated with this condition.
Early testing and diagnosis are crucial for individuals with X-ALD, as early intervention can help manage symptoms and improve outcomes. Information about genetic testing and resources for individuals and families affected by X-ALD can be found through organizations such as the National Adrenoleukodystrophy Foundation (NALD), clinicaltrials.gov, and the Orphanet portal.
Research and scientific studies are ongoing to better understand X-ALD and develop potential treatments. Currently, there are several clinical trials and research studies focused on X-ALD listed on clinicaltrials.gov.
Learn more about the gene associated with X-linked adrenoleukodystrophy
X-linked adrenoleukodystrophy (X-ALD) is a rare genetic disorder that affects the nervous system and adrenal glands. It is caused by mutations in the ABCD1 gene, which is located on the X chromosome.
The ABCD1 gene provides instructions for making a protein called ALDP, which is responsible for transporting very long-chain fatty acids (VLCFAs) into the peroxisome, a cell organelle involved in lipid metabolism. In individuals with X-ALD, mutations in the ABCD1 gene lead to a deficiency or malfunction of the ALDP protein, resulting in the accumulation of VLCFAs in various tissues, including the brain and adrenal glands.
X-ALD mainly affects males, as they have only one copy of the X chromosome. Females can also be affected, but the severity of the symptoms varies greatly due to X-chromosome inactivation. Female carriers of the ABCD1 gene mutation have a 50% chance of passing on the mutated gene to each of their children.
The symptoms of X-ALD can vary widely and may appear at any time, from early childhood to adulthood. The most common form of X-ALD is the childhood cerebral form, which typically presents between the ages of 4 and 10 and is characterized by progressive damage to the white matter of the brain. Other forms of X-ALD include adrenomyeloneuropathy, which affects the spinal cord, and adrenal insufficiency, which affects the adrenal glands.
Diagnosis of X-ALD can be done through genetic testing, which can identify mutations in the ABCD1 gene. Genetic counseling may also be recommended for individuals with a family history of X-ALD or those considering having children.
For additional information on X-ALD and the ABCD1 gene, you can visit the following resources:
- OMIM: Online Mendelian Inheritance in Man (OMIM) is a comprehensive catalog of human genes and genetic disorders. It provides detailed information on the genetic causes, inheritance patterns, and frequency of X-ALD.

Increased awareness and research into X-ALD and related disorders can contribute to improved diagnostics, management, and support for those affected.
Inheritance
X-linked adrenoleukodystrophy (ALD) is a genetic disorder that follows an X-linked inheritance pattern. This means that the gene mutation responsible for the condition is carried on the X chromosome. Since males have one X chromosome and one Y chromosome, a single copy of the mutated gene is enough to cause the disease. Females, on the other hand, have two X chromosomes. They typically need to inherit two copies of the mutated gene to develop symptoms of ALD.
X-linked adrenoleukodystrophy can be inherited in several different ways, resulting in different types and patterns of disease. The most common type is called the childhood cerebral form. This form usually appears in boys between the ages of 4 and 10 years old. It is characterized by progressive and severe neurological symptoms.
Other types of ALD include adrenomyeloneuropathy and adult-onset adrenoleukodystrophy. Adrenomyeloneuropathy is a milder form of the disease that typically appears in males during adolescence or adulthood. Adult-onset adrenoleukodystrophy primarily affects females and is associated with milder symptoms that usually appear later in life.
The genetic mutation that causes X-linked adrenoleukodystrophy is located in the ABCD1 gene. This gene provides instructions for producing a protein that is involved in the breakdown of certain fatty acids. When the ABCD1 gene is mutated, the protein is not produced correctly, leading to a buildup of fatty acids in the body.
The diagnosis of X-linked adrenoleukodystrophy is typically made based on clinical symptoms, family history, and genetic testing. Genetic testing can identify mutations in the ABCD1 gene and confirm the diagnosis. Early diagnosis is important for patients and their families to access appropriate medical, educational, and psychological support services.
More information about X-linked adrenoleukodystrophy and related conditions can be found in medical literature and resources such as scientific articles and databases like PubMed. There are also organizations and advocacy groups dedicated to supporting individuals affected by ALD, providing resources, and funding research studies.

Catalog of Genes and Diseases from OMIM
This catalog provides information about the genes and diseases associated with X-linked adrenoleukodystrophy. The content is derived from OMIM (Online Mendelian Inheritance in Man), a comprehensive resource that collects and curates information on genetic disorders and genes.
X-linked adrenoleukodystrophy (ALD) is a rare genetic disorder characterized by the accumulation of very long-chain fatty acids (VLCFAs) in various tissues, including the adrenal glands, white matter of the brain, and spinal cord. The condition can manifest in different forms, including childhood cerebral ALD, adolescent ALD, and adrenomyeloneuropathy (AMN).
The ALD gene, also known as the ABCD1 gene, is responsible for the production of a protein called ALDP (adrenoleukodystrophy protein). Mutations in the ABCD1 gene lead to a deficiency or dysfunction of ALDP, which impairs the transport of VLCFAs into peroxisomes. As a result, VLCFAs accumulate and cause damage to the myelin sheath, leading to the neurological symptoms observed in individuals with ALD.
