Succinate-CoA ligase deficiency, also known as suclg1 deficiency, is a rare genetic condition associated with the depletion of succinate-CoA ligase, an enzyme crucial for the metabolism of succinate-coenzyme A (succinyl-CoA). This condition is caused by mutations in the SUCGL1 gene, which result in the loss or reduction of the enzyme’s function.
Patients with succinate-CoA ligase deficiency can present with a wide range of symptoms, from mild to fatal, including developmental delay, encephalomyopathy, and metabolic aciduria. The frequency of the condition is very low, making it difficult to diagnose and study. However, with advancements in genetic testing and scientific resources, more is being learned about this rare condition.
In addition to the suclg1 gene, other genes have been found to be associated with succinate-CoA ligase deficiency. Some of these genes include Zeviani and Wibrand. These discoveries have led to a more comprehensive understanding of the condition and provided additional resources for patient support and advocacy.
Further research is needed to fully understand the causes and mechanisms of succinate-CoA ligase deficiency. More scientific articles and references are available on PubMed and OMIM, providing valuable information for healthcare professionals and researchers studying this condition. With increased awareness and support, we can improve the lives of individuals living with succinate-CoA ligase deficiency and contribute to the development of effective treatments.
Frequency
The frequency of Succinate-CoA ligase deficiency is not well documented, as it is a very rare condition. There is limited scientific knowledge and data available regarding the prevalence of this disorder.
Studies have shown that Succinate-CoA ligase deficiency is inherited in an autosomal recessive manner. This means that both copies of the gene responsible for the condition must be mutated for an individual to be affected.
Once you do get to see the doctor, don’t be surprised if you’re rushed out of the exam room before you get all of your questions answered, according to healthcare staffing agency Staff Care. Studies show that 41% of ophthalmologists spend just 9 to 12 minutes with a patient, and 13- to 16-minute appointments are the norm for 40% of cardiologists, 37% of pediatricians, 35% of urologists, 35% of family physicians, 34% of obstetricians and gynecologists and 30% of otolaryngologists.
According to the OMIM (Online Mendelian Inheritance in Man) database, mutations in the SUCLG1 gene are associated with Succinate-CoA ligase deficiency. Additional genes may also be involved in causing this condition, but research is ongoing to learn more about them.
Some individuals with Succinate-CoA ligase deficiency may have a milder form of the condition, while others may experience more severe symptoms. The signs and symptoms can vary widely among affected individuals.
According to the PubMed database, Succinate-CoA ligase deficiency can lead to a variety of developmental and neurological problems. It has been associated with encephalomyopathy, a condition affecting the brain and muscles.
The International Advocate for Glycogen Storage Disease (IAGSD) provides support and resources for individuals and families affected by Succinate-CoA ligase deficiency.
There is currently no cure for Succinate-CoA ligase deficiency. Treatment options focus on managing symptoms and providing supportive care.
More research and genetic testing are needed to better understand the underlying causes and mechanisms of Succinate-CoA ligase deficiency.

Causes
Succinate-CoA ligase deficiency is a rare condition associated with mutations in the SUCLG1 gene. The deficiency leads to a depletion of succinate-coenzyme A (CoA), which is a crucial molecule in the body’s energy production process.
There are several genetic mutations in the SUCLG1 gene that can cause succinate-CoA ligase deficiency. These mutations result in a loss or reduction of the enzyme’s normal function, leading to the symptoms and signs of the condition.
This condition is inherited in an autosomal recessive manner, which means that both copies of the SUCLG1 gene must have mutations for a person to develop the condition. If only one copy of the gene is affected, the individual is considered a carrier and typically does not show symptoms of the deficiency.
Succinate-CoA ligase deficiency is a very rare condition, and its exact frequency is unknown. It is estimated that only a few cases have been reported in the scientific literature. The condition is cataloged in the Online Mendelian Inheritance in Man (OMIM) database, which provides information on the genetic basis of inherited diseases.
Patient support resources, such as advocacy groups and online forums, may provide additional information and support for individuals with succinate-CoA ligase deficiency and their families. These resources can help patients and families learn more about the condition, connect with others facing similar challenges, and access helpful information and services.
Scientific articles and genetic testing can help in the diagnosis of succinate-CoA ligase deficiency. Testing for mutations in the SUCLG1 gene can confirm a diagnosis and provide important information about the specific mutations present. Genetic counseling may also be recommended for affected individuals and their families to discuss inheritance patterns and potential risks for future generations.
While succinate-CoA ligase deficiency can be a severe and potentially fatal condition, there are milder forms of the disease that allow individuals to live relatively normal lives. Treatment options may include dietary modifications, supportive care, and management of specific symptoms. Early detection and intervention can significantly improve the prognosis for individuals with succinate-CoA ligase deficiency.

Learn more about the genes associated with Succinate-CoA ligase deficiency
Succinate-CoA ligase deficiency is a rare genetic condition caused by mutations in the SUCLG1 gene. This condition affects the function of succinate-coenzyme A ligase, which is involved in the production of energy in cells.
Individuals with succinate-CoA ligase deficiency may experience a range of symptoms, including developmental delay, encephalomyopathy (a condition that affects the brain and muscles), and signs of metabolic aciduria. In some cases, the condition can be fatal.
The SUCLG1 gene provides instructions for making a protein that is part of the succinate-CoA ligase enzyme. Mutations in this gene can lead to a depletion or loss of enzyme function, resulting in the symptoms associated with succinate-CoA ligase deficiency.
There are additional genes associated with similar syndromes. Some examples include SUCLA2 and SUCLG2 genes. These genes also play a role in the function of succinate-CoA ligase and their mutations can lead to similar symptoms.
The frequency of succinate-CoA ligase deficiency is not well documented, as it is a very rare condition. However, it is believed to be inherited in an autosomal recessive pattern, meaning that both parents must carry a copy of the mutated gene in order for their child to be affected.
For more information on Succinate-CoA ligase deficiency and the associated genes, you can refer to the following resources:
- OMIM (Online Mendelian Inheritance in Man) catalog, which provides detailed information about genetic diseases and their associated genes

Inheritance
The inheritance pattern of Succinate-CoA ligase deficiency is autosomal recessive. This means that the condition is caused by mutations in both copies of the SUCLG1 or SUCLA2 gene.
Mutations in the SUCLG1 gene lead to the more severe form of the condition known as Succinate-CoA ligase deficiency, encephalomyopathic form (SCAE). On the other hand, mutations in the SUCLA2 gene lead to a milder form of the condition called Succinate-CoA ligase deficiency, mitochondrial type 2 (SCMC2).
Both genes are responsible for the production of subunits of the succinate-coenzyme A ligase enzyme, which plays a crucial role in the energy-generating process of the mitochondria. Mutations in these genes result in the impairment of this enzyme’s function, leading to a depletion of energy and the development of the signs and symptoms associated with Succinate-CoA ligase deficiency.
The condition is extremely rare, with only a few reported cases in the scientific literature. The frequency of occurrence is not well established. The OMIM catalog and PubMed are the primary resources to learn more about the condition and its inheritance pattern.
For genetic testing and additional information about Succinate-CoA ligase deficiency, patient advocacy organizations, such as the Zeviani Syndrome Association, can provide support and resources for individuals and families living with this rare condition.
