Adenylosuccinate lyase deficiency, also known as ADSL deficiency, is a rare genetic condition that affects the human body. It is caused by a deficiency of the adenylosuccinate lyase (ADSL) enzyme, which converts adenylosuccinate to AMP (adenosine monophosphate) and fumarate. ADSL deficiency is associated with a variety of clinical traits, including intellectual disability, developmental delay, seizures, and microcephaly.

This condition has been found in a small number of individuals around the world. In the scientific community, it is also referred to as SAICAR synthetase deficiency, since ADSL deficiency leads to accumulation of SAICAR (succinyladenosine monophosphate) in the body. The inheritance of ADSL deficiency follows an autosomal recessive pattern, meaning that both parents must carry a mutated ADSL gene for their child to be affected.

Research on ADSL deficiency is ongoing, with studies investigating the causes, severity, and additional traits associated with the condition. Resources such as OMIM (Online Mendelian Inheritance in Man), PubMed, and ClinicalTrials.gov provide information on the latest scientific findings, clinical studies, and genetic testing for ADSL deficiency. These resources are essential for physicians, researchers, and advocacy organizations to support patients and families affected by this rare genetic condition.

ADSL deficiency was first described in 1989 by Zikanova et al. Several articles and references in the scientific literature have since discussed the different forms and frequency of ADSL deficiency. The Online Mendelian Inheritance in Man (OMIM) catalog and the ClinicalTrials.gov database are valuable sources of information about ADSL deficiency, including its genetic basis, associated diseases, and available clinical trials. With ongoing research and medical advancements, it is hoped that more effective treatments and support for individuals with ADSL deficiency will become available in the future.

Frequency

The frequency of adenylosuccinate lyase deficiency is very rare, estimated to affect less than 1 in 1,000,000 individuals worldwide. This condition is considered a genetic disorder and is inherited in an autosomal recessive manner.

According to scientific studies and patient support resources, the severity of adenylosuccinate lyase deficiency can vary from mild to severe. Some individuals may experience developmental delay, intellectual disability, and other neurological symptoms, while others may have milder forms of the condition.

Part of the reason for these long wait times and short appointments is due to a nationwide shortage of physicians that is only getting worse. A report by the Association of American Medical Colleges predicts that, due to population growth and specifically growth of the elderly population, the physician shortfall in the U.S. could reach 121,300 by the year 2030.

The ADSL gene, which is responsible for producing the enzyme adenylosuccinate lyase, is associated with this condition. Mutations in the ADSL gene can cause a deficiency in the enzyme’s activity, leading to the buildup of saicar and other adenylosuccinate metabolites.

Testing for adenylosuccinate lyase deficiency can be done through genetic testing, which analyzes the ADSL gene for mutations. Additional clinical and biochemical tests may also be performed to confirm the diagnosis.

There are currently no known cures for adenylosuccinate lyase deficiency, but treatment options may include supportive care, therapy to manage symptoms, and genetic counseling for affected individuals and their families.

For more information about adenylosuccinate lyase deficiency, its inheritance patterns, clinical trials, and research articles, the following resources may be helpful:

  • OMIM: The Online Mendelian Inheritance in Man database provides detailed information about the ADSL gene and associated condition.
  • PubMed: The National Library of Medicine’s database of scientific articles contains research studies about adenylosuccinate lyase deficiency and related topics.

  • ClinicalTrials.gov: This website lists ongoing clinical trials related to adenylosuccinate lyase deficiency that are open for patient enrollment.

Causes

The causes of Adenylosuccinate lyase deficiency are genetic mutations in the ADSL gene. This gene provides instructions for making the enzyme adenylosuccinate lyase, which is involved in the breakdown and recycling of nucleotides in the body.

When there is a mutation in the ADSL gene, the enzyme is not produced correctly or is produced in insufficient amounts. This leads to a deficiency of adenylosuccinate lyase, resulting in the accumulation of toxic substances such as succinyladenosine (SuAd), succinylaminoimidazolecarboxamide riboside (SAICAr), and succinyladenosine monophosphate (SAMP) in the body.

These toxic substances interfere with normal cellular processes and can cause a wide range of symptoms and complications, including intellectual disability, developmental delay, microcephaly (abnormally small head size), seizures, autistic features, and other neurological and behavioral problems.

Adenylosuccinate lyase deficiency is inherited in an autosomal recessive manner, which means that an affected individual must inherit two mutated copies of the ADSL gene, one from each parent. Individuals who inherit only one mutated copy of the gene are carriers and typically do not show symptoms of the condition.

There are additional genes that have been associated with similar clinical features as Adenylosuccinate lyase deficiency, such as the AICA-ribosiduria (AIAS) due to AICAR transformylase/IMP cyclohydrolase (ATIC) deficiency. These related diseases have similar symptoms but are caused by mutations in different genes.

Genetic testing is available to confirm a diagnosis of Adenylosuccinate lyase deficiency. Testing can identify mutations in the ADSL gene that are responsible for the condition. The Genetic Testing Registry (GTR) provides information about the available genetic tests for this and other rare genetic disorders.

For more scientific information about Adenylosuccinate lyase deficiency, clinical trials, and research articles, you can refer to resources such as PubMed, OMIM (Online Mendelian Inheritance in Man), and the ClinicalTrials.gov database.

Learn more about the gene associated with Adenylosuccinate lyase deficiency

Adenylosuccinate lyase deficiency, also known as ADSL deficiency, is a rare genetic condition caused by mutations in the ADSL gene. This gene provides instructions for making an enzyme called adenylosuccinate lyase. The ADSL gene is located on chromosome 22, specifically at position 22q13.1.

Adenylosuccinate lyase is involved in the breakdown and recycling of purine nucleotides, which are important building blocks of DNA and RNA. This enzyme converts adenylosuccinate, a molecule involved in the synthesis of the nucleotide adenine, into another molecule called AMP (adenosine monophosphate).

When the ADSL gene is mutated, adenylosuccinate lyase deficiency occurs. This condition affects the production of AMP, leading to the buildup of a molecule called succinylaminoimidazole carboxamide riboside (SAICAR). The accumulation of SAICAR is toxic to cells, particularly in the brain, and can cause a range of symptoms.

Adenylosuccinate lyase deficiency is associated with two main forms: a severe form called early-onset epileptic encephalopathy, and a milder form called developmental delay with or without autism. The severity and specific symptoms of the condition can vary widely from person to person.

Research studies have identified various mutations in the ADSL gene that can cause adenylosuccinate lyase deficiency. These mutations can affect the function of the enzyme or its production. Understanding the specific genetic cause of the condition can help in diagnosing and managing the disorder.

Inheritance

Adenylosuccinate lyase deficiency is an inherited genetic condition caused by mutations in the ADSL gene. The inheritance pattern of this condition is autosomal recessive, meaning that both copies of the gene, one inherited from each parent, must be altered to have the condition.

Parents who each carry one copy of the mutated gene are referred to as carriers. Carriers do not typically show signs or symptoms of the condition but can pass the altered gene to their children. When two carriers have children together, there is a 25% chance with each pregnancy to have a child with adenylosuccinate lyase deficiency.

The frequency of this condition is rare, with an estimated prevalence of about 1 in 200,000 individuals worldwide. The severity of the condition can vary between individuals, with some experiencing more severe symptoms than others.

For more information on the inheritance and characteristics of adenylosuccinate lyase deficiency, you can refer to the OMIM catalog (OMIM #103050). The ADSL gene is located on chromosome 22.

There are several associated traits and features of adenylosuccinate lyase deficiency, including intellectual disability, developmental delay, seizures, and autism spectrum disorder. Microcephaly, or abnormally small head size, is also commonly seen in affected individuals.

Samp, a support and advocacy center for individuals and families affected by adenylosuccinate lyase deficiency, provides additional resources and support for those seeking assistance.
