Autosomal dominant leukodystrophy with autonomic disease (ADLD) is a rare genetic disorder that affects the central nervous system. It is characterized by progressive changes in the white matter of the brain, which leads to a range of symptoms, including autonomic dysfunction.
ADLD usually begins in adulthood and worsens with time. The most common symptoms include bladder and bowel control problems, changes in blood pressure and heart rate, and abnormal sweating. These autonomic dysfunctions are caused by the degeneration of the nerve fibers responsible for controlling these bodily functions.
The exact cause of ADLD is still unknown, but it is believed to be caused by a duplication of a gene on chromosome 5. This duplication leads to an abnormal production of a protein, which plays a role in the formation and maintenance of myelin, the protective coating around nerve fibers. When the myelin is affected, it disrupts the flow of nerve impulses and leads to the symptoms associated with ADLD.
Diagnosis of ADLD can be confirmed through genetic testing, which looks for the specific gene duplication associated with the condition. Currently, there is no cure for ADLD, and treatment focuses on managing symptoms and providing support to affected individuals. Additional resources and support for individuals with ADLD can be found through various advocacy organizations and scientific articles on PubMed and OMIM.

Frequency
The frequency of autosomal dominant leukodystrophy with autonomic disease (ADLD) is not well established. This is likely due to the fact that ADLD is a rare condition and there may be many undiagnosed cases. According to the scientific literature, ADLD is estimated to affect less than 1 in 1,000,000 individuals.
ADLD was first described in 1984 by Huang et al. in a family with adult-onset autonomic dysfunction and white matter changes in the brain. Since then, additional cases and families with ADLD have been reported in the scientific literature. The exact prevalence of ADLD is difficult to determine because there may be other genetic conditions with similar symptoms and inheritance patterns.
In the U.S., healthcare spending accounts for 17.7% of the Gross Domestic Product (GDP), or the total value of goods and services produced by the entire nation for the entire year, according to the Centers for Medicare & Medicaid Services.
Genetic testing is currently the most accurate method to confirm a diagnosis of ADLD. Testing can identify mutations in the LMNB1 gene, which is the primary gene associated with ADLD. Mutations in this gene lead to the production of an abnormal form of lamin B1, a protein involved in the structure and function of the nucleus. It is believed that this abnormal lamin B1 protein interferes with the normal functioning of nerve cells in the central nervous system, including those that control autonomic functions such as bladder control, blood pressure, and other involuntary movements.
Inheritance of ADLD is autosomal dominant, which means that an affected individual has a 50% chance of passing the condition on to each of their children. However, not all individuals with a mutation in the LMNB1 gene will develop symptoms of ADLD. This is known as reduced penetrance, and the exact mechanisms behind this phenomenon are not yet fully understood.
For more information on genetic testing and resources for patients and families affected by ADLD, advocacy organizations such as the Adult-Onset Leukodystrophy (ALD) Support and Advocacy Network (ALDSAN) and the United Leukodystrophy Foundation (ULF) provide support, educational materials, and resources to learn more about the condition.
Causes
Autosomal dominant leukodystrophy with autonomic disease (ADLD) is a genetic condition that affects the nervous system, specifically the brain and autonomic (involuntary) functions. The condition is caused by a duplication of the gene LMNB1 on chromosome 5q23.2.
ADLD is an autosomal dominant condition, which means that a person only needs to inherit one copy of the affected gene from one parent in order to develop the condition. The genetic cause of ADLD was identified in 2002, and since then, several additional genes have been associated with the condition.
The duplications of the LMNB1 gene result in excessive production of lamin B1 protein, which plays a central role in the structure and function of the nucleus. The accumulation of this protein in the brain leads to the loss of myelin, which is the protective covering of nerve fibers. This loss of myelin causes the symptoms of leukodystrophy, including problems with movement, coordination, and autonomic function.
More about the genetic causes of ADLD can be learned from scientific resources such as PubMed, OMIM, and gene catalogs. These resources provide information about the genes involved in the condition and their inheritance patterns.
It is important for patients and their families to seek genetic testing and counseling in order to better understand the genetic basis of ADLD and receive appropriate support and information. Advocacy organizations and support groups can also provide additional resources and information for affected individuals and their families.

Autosomal dominant leukodystrophy with autonomic disease (ADLD) is a rare genetic condition that affects the nervous system. It is characterized by changes in the brain’s white matter, which leads to movement and autonomic dysfunction.
ADLD is caused by a duplication of the LMNB1 gene, which plays a role in the production of lamin B1 protein. This protein is important for the structure and function of the central nervous system. The duplication of the LMNB1 gene leads to an excess production of lamin B1 protein, which disrupts normal nerve cell function.
The inheritance of ADLD is autosomal dominant, meaning that a person only needs to inherit one copy of the LMNB1 gene with the duplication to be affected by the condition. This pattern of inheritance causes ADLD to run in families.
Adult-onset of ADLD typically occurs in the 20s or 30s, although it can start later in life. The symptoms of ADLD worsen over time and can include problems with movement, bladder control, and autonomic functions such as blood pressure and heart rate regulation.
There are currently no specific treatments for ADLD, but there are supportive therapies available to help manage the symptoms. Genetic testing can be used to confirm a diagnosis of ADLD by identifying the duplication of the LMNB1 gene.
For more information about ADLD and the gene associated with it, you can refer to the following resources:
- OMIM: This online catalog of human genes and genetic disorders provides detailed information on ADLD and the LMNB1 gene.
- Additional articles and references: There are numerous scientific articles and references available that provide further information on ADLD and the associated gene.
- Support organizations: There are support organizations available that provide resources and information for individuals and families affected by ADLD.
By learning more about the gene associated with ADLD, we can better understand the condition and potentially develop new treatments and therapies to support affected individuals.
Inheritance
This central nervous system disorder is inherited in an autosomal dominant manner, meaning that a person with one copy of the mutated gene in each cell is affected. It is an adult-onset disease, with symptoms typically appearing in the third or fourth decade of life. However, there have been cases of earlier-onset disease reported.
Autosomal dominant leukodystrophy with autonomic disease (ADLD) is associated with changes in a gene called LMNB1. This gene provides instructions for making a protein called lamin B1 that is found in the nucleus of cells. Mutations in the LMNB1 gene cause an autosomal dominant duplication of the gene, which leads to the production of an abnormally increased amount of lamin B1 protein. It is the increased production of this protein that causes the associated symptoms of ADLD.
Symptoms of ADLD include autonomic dysfunction, such as bladder control problems and abnormal movements. The disease progressively worsens over time, leading to severe neurological impairment. The central nervous system, including the brain and spinal cord, is most affected.
Genetic testing can confirm a diagnosis of ADLD by identifying mutations in the LMNB1 gene. Additional testing may be required to rule out other genetic causes of leukodystrophy with autonomic disease.
