3-hydroxy-3-methylglutaryl-CoA lyase deficiency

3-hydroxy-3-methylglutaryl-CoA lyase deficiency, also known as HMGCL deficiency, is a rare genetic condition that affects the body’s ability to break down certain fats for energy. This condition is caused by mutations in the HMGCL gene.

Patients with 3-hydroxy-3-methylglutaryl-CoA lyase deficiency may experience a variety of symptoms, including vomiting, lethargy, hypotonia, and seizures. The severity of the condition can vary widely, with some individuals experiencing milder symptoms while others may have more severe complications.

Research studies have been conducted to learn more about 3-hydroxy-3-methylglutaryl-CoA lyase deficiency and its causes. Additional information about this condition can be found in the scientific literature, including articles in PubMed and OMIM. Patients and their families can find support and advocacy resources from organizations such as Puisac et al., the Genetic and Rare Diseases Information Center, and ClinicalTrials.gov.

Genetic testing is available to confirm a diagnosis of 3-hydroxy-3-methylglutaryl-CoA lyase deficiency. Inheritance of this condition follows an autosomal recessive pattern, meaning that an affected individual must inherit two copies of the mutated gene, one from each parent. The frequency of this deficiency is currently unknown.

While there is no cure for 3-hydroxy-3-methylglutaryl-CoA lyase deficiency, treatment options are available to manage the symptoms and complications associated with the condition. It is important for patients and their families to work closely with healthcare providers to develop an individualized treatment plan.

Frequency

The frequency of 3-hydroxy-3-methylglutaryl-CoA lyase deficiency is not well known, but it is considered to be a rare condition. The exact number of affected individuals worldwide is unknown.

From the available information on OMIM, it seems that most cases of 3-hydroxy-3-methylglutaryl-CoA lyase deficiency are identified in individuals with symptoms. Additional cases may exist with mild or subtle symptoms that have not been recognized or reported.

The deficiency is inherited in an autosomal recessive manner, which means that both copies of the HMGCL gene in each cell have mutations.

Advocacy organizations can provide more information about the condition and support for affected individuals and their families.

Research studies are ongoing to further understand the causes, inheritance patterns, and treatment options for this condition.

Testing for mutations in the HMGCL gene is available, and it can confirm a diagnosis in individuals with symptoms consistent with 3-hydroxy-3-methylglutaryl-CoA lyase deficiency.

There are no other known diseases associated with mutations in the HMGCL gene.

References for this condition can be found in the OMIM catalog of human genes and genetic disorders, including the HMGCL gene.

To learn more about the condition or participate in research studies, you can contact your local genetic counseling center or search for clinical trials on ClinicalTrials.gov or PubMed.

Causes

3-hydroxy-3-methylglutaryl-CoA lyase deficiency is a rare genetic disorder. It is associated with mutations in the HMGCL gene, which is responsible for producing an enzyme called 3-hydroxy-3-methylglutaryl-CoA lyase. This enzyme plays a key role in breaking down a specific type of fat called ketones for energy.

The frequency of HMGCL gene mutations in the general population is not well known. However, scientific studies and patient support organizations, such as the Puisac et al. catalog and the Center for Human Genetics, provide resources with names of known genetic conditions associated with HMGCL gene deficiency.

During research on this condition, scientific articles and clinical trials listed on PubMed and ClinicalTrials.gov may offer more information on the inheritance patterns and causes of 3-hydroxy-3-methylglutaryl-CoA lyase deficiency. One study published in the American Journal of Medical Genetics identified specific genetic mutations in the HMGCL gene that lead to this deficiency.

In addition to HMGCL gene mutations, other causes of this deficiency are still being studied. Several other genes and genetic defects have been identified that may contribute to the development of this condition.

To learn more about the causes of 3-hydroxy-3-methylglutaryl-CoA lyase deficiency, additional research and testing are needed. Resources such as the Online Mendelian Inheritance in Man (OMIM) database and advocacy organizations can provide further information and support for individuals and families affected by this condition.

Learn more about the gene associated with 3-hydroxy-3-methylglutaryl-CoA lyase deficiency

3-hydroxy-3-methylglutaryl-CoA lyase deficiency is a rare genetic condition that affects the HMGCL gene. This gene provides instructions for making an enzyme called 3-hydroxy-3-methylglutaryl-CoA lyase, which is involved in a process called ketogenesis. Ketogenesis is the breakdown of a molecule called acetyl-CoA, which is used to produce energy when glucose is not available.

Individuals with 3-hydroxy-3-methylglutaryl-CoA lyase deficiency have a mutation in the HMGCL gene that impairs the function of the 3-hydroxy-3-methylglutaryl-CoA lyase enzyme. This leads to a buildup of certain molecules, such as 3-hydroxy-3-methylglutaric acid, in the body. These molecules can be toxic to cells and tissues, causing the signs and symptoms associated with the condition.
