Frequency

Cerebral folate transport deficiency, also known as folinic acid-responsive seizures and complex childhood onset motor and mental retardation syndrome, is a rare genetic disease associated with mutations in the genes called FOLR1 and FOLR2. The condition is characterized by impaired transport of folate from the choroid plexus into the brain, leading to a deficiency of folate in the cerebral spinal fluid.

The frequency of cerebral folate transport deficiency is not well established, as it is a rare condition. According to OMIM, there have been only a few reported cases of this disease. The exact prevalence is not known, but it is estimated to be extremely rare.

Genetic testing is often required for a definitive diagnosis of cerebral folate transport deficiency. Additional research and clinical studies are needed to learn more about the frequency and genetic causes of this condition.

Causes

Cerebral folate transport deficiency (CFTD) is a rare genetic condition caused by mutations in the FOLR1 gene. This gene is responsible for producing a protein called folate receptor alpha, which plays a crucial role in transporting folate into the brain.

CFTD is inherited in an autosomal recessive manner, which means that an individual must inherit two copies of the mutated gene (one from each parent) in order to develop the condition. Individuals who inherit only one mutated copy of the gene are carriers and typically do not have symptoms of CFTD.

There are currently more than 30 known mutations in the FOLR1 gene that have been associated with CFTD. These mutations can disrupt the function of the folate receptor alpha protein, leading to a deficiency of folate in the brain.

The exact frequency of CFTD is unknown, but it is considered a rare condition. It has been reported in individuals from various ethnic backgrounds.

In addition to genetic causes, there are other factors that can contribute to CFTD. Some individuals with CFTD have a mutation in a gene called SLC46A1, which is involved in folate metabolism. Other individuals with CFTD have abnormalities in the choroid plexus, which is responsible for production of cerebrospinal fluid and plays a role in folate transport.

Further research is needed to understand the precise mechanisms underlying CFTD and how these factors interact with each other.

Learn more about the gene associated with Cerebral folate transport deficiency

Cerebral folate transport deficiency is a rare genetic condition that affects the transport of folate to the brain. This condition, also known as folate receptor 1 (FOLR1) deficiency, is caused by mutations in the FOLR1 gene.

The FOLR1 gene provides instructions for making a protein called folate receptor alpha. This protein is found in various tissues, including the brain, where it helps transport folate into cells. Folate is an important nutrient that is necessary for the production of DNA and the normal functioning of the nervous system.

Without the proper functioning of the FOLR1 protein, folate cannot be transported into the brain effectively. This leads to a decrease in the levels of folate in the brain, which can result in neurological problems characteristic of cerebral folate transport deficiency.

Research studies and scientific articles have provided valuable information about the causes, inheritance patterns, clinical features, and treatment options for this condition. Some of the resources available include:

OMIM: OMIM is a catalog of human genes and genetic disorders. It provides information on the FOLR1 gene, including its gene symbol, chromosome location, and inheritance pattern.
PubMed: PubMed is a database of scientific articles. It contains numerous studies on cerebral folate transport deficiency, its genetic basis, and potential treatments.

Inheritance

Cerebral folate transport deficiency (CFTD) is a genetic condition that is inherited in an autosomal recessive manner. This means that an individual must inherit two copies of the abnormal gene, one from each parent, in order to develop the condition.

The genetic cause of CFTD is mutations in the FOLR1 gene. This gene provides instructions for making a protein that is involved in transporting folate into the brain. Mutations in the FOLR1 gene result in a decrease in the amount of folate that is able to enter the brain, leading to the signs and symptoms of CFTD.

There are currently no other known genetic causes of CFTD. Ongoing research is focused on understanding the underlying genetic mechanisms and identifying potential therapeutic targets for treatment.

More information about the inheritance and genetics of CFTD can be found in the OMIM entry for CFTD (OMIM 613068).

The Cerebral Folate Transport Deficiency Research Center (CFTDRC), led by Dr. Garcia-Cazorla, is a scientific center dedicated to studying CFTD. The center conducts research studies and clinical trials to better understand the condition and develop new treatments.

Genetic Testing Information

Cerebral folate transport deficiency is a rare genetic condition caused by mutations in the FOLR1 gene. It is inherited in an autosomal recessive manner.

The FOLR1 gene provides instructions for making a protein that is involved in the transport of folate into the brain. Without a functional FOLR1 gene, the brain is unable to properly take in folate, leading to neurological problems.

Genetic testing can be used to confirm a diagnosis of cerebral folate transport deficiency. This testing looks for mutations in the FOLR1 gene that are known to be associated with the condition.

There are other genes that have been associated with a similar condition without mutations in the FOLR1 gene. This condition is called cerebral folate receptor alpha (FOLR1)-negative syndrome.

Patients with cerebral folate transport deficiency or cerebral folate receptor alpha-negative syndrome may also have mutations in other genes that have not yet been identified.

It is important for patients and their families to seek appropriate genetic counseling to understand the inheritance pattern and associated risks for future children.

There are currently no specific treatments for cerebral folate transport deficiency. However, research studies and clinical trials are ongoing to better understand the disease and develop potential treatments.

Genetic and Rare Diseases Information Center

The Genetic and Rare Diseases Information Center (GARD) provides reliable, scientific information on cerebral folate transport deficiency (CFTD). CFTD is a genetic condition associated with mutations in the FOLR1 gene. It affects the transport of folate into the brain and can result in neurological symptoms and leukodystrophy, a disorder affecting the myelin, the protective covering of nerve fibers in the brain.

People with CFTD have difficulties with the transportation of folate, an essential vitamin, into the brain. The choroid plexuses, which produce cerebrospinal fluid, play a critical role in this process. When folate does not reach the brain, it can lead to developmental delays, seizures, movement problems, and cognitive impairment.

There is currently no cure for CFTD, but treatment options are focused on managing the symptoms and providing supportive care. It is important for patients and caregivers to learn about available resources, such as patient support organizations and advocacy groups, that can provide additional information and assistance.

Genetic Information

CFTD has an autosomal recessive pattern of inheritance, meaning that individuals must inherit two copies of the mutated gene, one from each parent, to develop the condition. Mutations in the FOLR1 gene prevent the normal transport of folate into the brain, leading to the symptoms of CFTD.

CFTD is a rare disease, with a frequency of less than 1 in 1,000,000 people. It is important for individuals with suspected CFTD to undergo genetic testing to confirm the diagnosis and identify the specific gene mutations involved.

Research Studies from ClinicalTrialsgov

There are several research studies conducted on cerebral folate transport deficiency, also known as a rare genetic disease called folate receptor 1 (FOLR1) deficiency. This condition is associated with a recessive gene mutation that affects the transport of folate (a type of vitamin B9) across the blood-brain barrier. Without proper folate transport, the brain lacks sufficient folate, leading to neurological symptoms and myelin abnormalities.

One of the research studies conducted on cerebral folate transport deficiency is by Garcia-Cazorla et al. In this study, the authors investigated the clinical, genetic, neuroimaging, and biochemical characteristics of patients with this condition. They found that the frequency of FOLR1 deficiency is rare, and it is associated with leukodystrophy (a group of rare genetic disorders that affect the white matter of the brain) and other neurological symptoms. The study provides valuable information on the disease’s causes and inheritance patterns.

Another study by Toma et al. focused on the testing and treatment options for patients with cerebral folate transport deficiency. The researchers explored the use of folinic acid, a form of folate that can cross the blood-brain barrier without the need for transport proteins. They studied the effects of folinic acid supplementation on patients with FOLR1 deficiency and observed improvements in neurological symptoms, myelin abnormalities, and folate levels in the cerebrospinal fluid.
