Fatty Acid Hydroxylase-Associated Neurodegeneration (FAHN) is a rare genetic neurological condition that leads to rapid loss of myelin, the white substance that surrounds nerve fibers in the brain. FAHN is caused by mutations in a gene called FA2H, which is responsible for producing an enzyme involved in the synthesis of certain fatty acids. These fatty acids play an essential role in the formation and maintenance of myelin.

Individuals with FAHN typically develop neurological problems in infancy or childhood, including difficulty walking, muscle weakness, and problems with swallowing. The condition is also characterized by a loss of white matter in the brain, which can be visualized through magnetic resonance imaging (MRI).

FAHN is inherited in an autosomal recessive manner, meaning that both copies of the FA2H gene must be mutated in order for the condition to manifest. The frequency of FAHN is currently unknown, but it is considered to be a very rare disorder.

Currently, there is no cure for FAHN, and treatment focuses on managing symptoms and providing supportive care. Research on FAHN is ongoing, and scientists are working to better understand the genetic and molecular mechanisms underlying the condition. Additional studies are also needed to develop more effective treatments for individuals with FAHN.

For more information about FAHN, genetic testing, and support resources, individuals and families can visit websites such as OMIM (Online Mendelian Inheritance in Man), PubMed, or the Fatty Acid Hydroxylase-Associated Neurodegeneration Center. These resources provide information on clinical trials, scientific research articles, and advocacy organizations that are dedicated to supporting individuals with FAHN and other related disorders.

Frequency

Fatty acid hydroxylase-associated neurodegeneration (FAHN) is a rare condition that is caused by genetic problems with fatty acid hydroxylase genes. This condition is also known as Neurodegeneration with Brain Iron Accumulation (NBIA).

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.

The frequency of FAHN is not well-documented due to its rarity. According to the Hayflick et al. (2013) catalog, only a few individuals have been diagnosed with FAHN. The Inherited Neurometabolic Disorders (INMD) program at the National Institute of Neurological Disorders and Stroke (NINDS) has additional information on FAHN and other related neurological disorders.

Research studies and clinical trials registered on ClinicalTrials.gov may provide more information on the frequency of FAHN. However, further research is needed to determine the exact prevalence of this condition.

FAHN is inherited in an autosomal recessive manner, meaning that both parents must carry a mutated gene for their child to develop the condition. The exact genes involved in FAHN are not specified in the available resources.

Individuals with FAHN may experience a range of clinical symptoms and signs, including muscle loss, swallowing problems, and neurodegeneration. The loss of fatty acids in the myelin of white matter in the brain is associated with these symptoms.

To learn more about FAHN and its associated genes, you can refer to scientific articles available on PubMed and Online Mendelian Inheritance in Man (OMIM) database. These resources provide more information on the genetics, inheritance, clinical features, and diagnostic testing for FAHN.

For more support and advocacy resources related to FAHN, you can visit the NBIA Disorders Association or reach out to the International Advocacy and Support Center for NBIA Disorders. They provide information, support, and resources for individuals and families affected by FAHN and related conditions.

Causes

Fatty acid hydroxylase-associated neurodegeneration is a genetic condition that is caused by mutations in the FA2H gene. This gene provides instructions for making an enzyme called fatty acid 2-hydroxylase, which is involved in the synthesis of myelin, the protective covering of nerve fibers. Mutations in the FA2H gene lead to a deficiency or malfunction of the enzyme, resulting in the accumulation of abnormal fatty acids in the brain. This accumulation disrupts myelin production and causes progressive neurological problems.

These mutations can be inherited in an autosomal recessive manner, which means that both copies of the FA2H gene must be mutated to develop the condition. Individuals who carry one copy of the mutated gene are referred to as carriers and typically do not experience symptoms of the condition.

There are also rare cases of Fatty acid hydroxylase-associated neurodegeneration that are not caused by mutations in the FA2H gene. These cases are classified as “idiopathic” or of unknown cause.

Other genetic forms of neurodegeneration can also cause similar symptoms to Fatty acid hydroxylase-associated neurodegeneration. Conditions such as hereditary spastic paraplegias, infantile neuroaxonal dystrophy, and multiple sclerosis-like syndrome can lead to similar clinical presentations.

Research is ongoing to better understand the genetic causes and mechanisms of Fatty acid hydroxylase-associated neurodegeneration. Genetic testing for mutations in the FA2H gene is available and can help confirm a diagnosis. Additional studies and clinical trials are being conducted to find potential treatments for this condition.

Individuals with FAHN typically experience rapid neurodegeneration, leading to problems with movement, muscle weakness, and swallowing difficulties. This condition can also cause additional neurological symptoms, such as loss of coordination, tremors, and psychiatric problems.

The inheritance pattern of FAHN is autosomal recessive, which means that an individual must inherit two copies of the mutated FA2H gene (one from each parent) to develop the condition. Carriers of a single copy of the mutated gene usually do not have any symptoms but can pass the gene on to their children.

Researchers have identified several mutations in the FA2H gene associated with FAHN. The OMIM database provides a catalog of these mutations, along with information on the frequency of each mutation in different populations.

ClinicalTrials.gov is a useful resource for finding ongoing research and clinical trials related to FAHN.

Inheritance

Fatty acid hydroxylase-associated neurodegeneration (FAHN) is an inherited condition. It is caused by changes (mutations) in the FA2H gene. This gene provides instructions for making an enzyme called fatty acid 2-hydroxylase, which is involved in the production of certain fats called fatty acids.

FAHN is inherited in an autosomal recessive pattern, which means that both copies of the FA2H gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but typically do not show signs and symptoms of the condition.

Conditions associated with FAHN include:

  • Neurological problems such as muscle stiffness, difficulty with swallowing, and loss of muscle control.
  • White matter abnormalities in the brain.
  • Rapid neurological degeneration.

Further information about the inheritance and genetic causes of FAHN can be found in scientific articles on websites such as PubMed and OMIM. These resources provide additional information on the genetics and clinical presentation of FAHN, as well as ongoing research and potential treatments.

Genetic testing is available to confirm a diagnosis of FAHN. This testing can identify mutations in the FA2H gene and help determine the likelihood of passing the condition on to future generations.

It is important for individuals and families affected by FAHN to seek support and advocacy from organizations such as the Fatty Acid Hydroxylase-Associated Neurodegeneration (FAHN) Advocacy Support Center.
