The DLD gene, also known as dihydrolipoamide dehydrogenase, is an essential gene that plays a crucial role in cellular function. It is listed as one of the genes responsible for the Leigh syndrome, a genetic disorder that affects the central nervous system. The DLD gene codes for an enzyme called dihydrolipoamide dehydrogenase, which is a component of three essential mitochondrial enzyme complexes. These complexes are involved in the breakdown of carbohydrates and the production of energy in cells.

Scientific research related to the DLD gene can be found in various databases and resources such as OMIM, PubMed, and genetic testing registries. Additional information and articles on the gene and related diseases can be found in these resources. The gene has also been linked to other conditions that affect liver and cellular health.

Mutations and changes in the DLD gene can lead to dysfunction of the enzyme, causing a range of genetic conditions. The variants of the gene have been identified through genetic testing and are named based on the changes and component affected by the mutation. Testing for the DLD gene is available to provide diagnostic information for individuals with suspected genetic disorders.

In conclusion, the DLD gene is an essential gene involved in the metabolic reaction and cellular function. Understanding its function and the changes in the gene is crucial for diagnosing and researching various genetic conditions. The gene plays a significant role in human health, and further scientific research and testing are necessary to fully understand its impact on various diseases and conditions.

Genetic changes in the DLD gene have been found to be related to various health conditions. These changes can lead to dysfunction in the cellular function of the gene, resulting in a reaction of the cells that can affect overall health.

One of the health conditions associated with genetic changes in the DLD gene is the pyruvate dehydrogenase complex deficiency, also known as the DLD deficiency syndrome. This syndrome affects the function of the pyruvate dehydrogenase enzyme, which is an essential component in the liver for the conversion of pyruvate into energy. Genetic changes in the DLD gene can disrupt this process, leading to a range of symptoms and diseases.

In studies, the artificial intelligence (AI) technology used in some online health services for preliminary screening before connecting patients with a doctor actually outperformed real physicians in terms of reaching an accurate diagnosis, CNN AI technology correctly diagnosed conditions in 81% of patients, compared to a 72% average for accurate diagnoses among real physicians over a five-year period.

The DLD gene is part of a complex and interconnected network of genes and cellular functions. Changes in the DLD gene can therefore have a ripple effect on other genes and complexes, further impacting health conditions. Understanding these relationships is essential for the diagnosis and treatment of related diseases.

For additional information on health conditions related to genetic changes in the DLD gene, the following resources may be useful:

  • OMIM: This online catalog of human genes and genetic disorders provides detailed information on the DLD gene and related health conditions.

  • PubMed: A scientific database that contains articles and research studies on the DLD gene and its role in various health conditions.

Dihydrolipoamide dehydrogenase deficiency

Dihydrolipoamide dehydrogenase deficiency, also known as DLD deficiency, is a rare genetic disorder that affects the function of the dihydrolipoamide dehydrogenase (DLD) enzyme.

The DLD enzyme is an essential component of the pyruvate dehydrogenase complex, the α-ketoglutarate dehydrogenase complex, and the branched-chain α-keto acid dehydrogenase complex. These complexes are responsible for the conversion of pyruvate, α-ketoglutarate, and branched-chain α-keto acids into acetyl-CoA, succinyl-CoA, and other intermediates that are essential for cellular energy production.

In individuals with DLD deficiency, genetic changes in the DLD gene result in reduced or absent DLD enzyme activity. This leads to a disruption in the function of the affected complexes and impairs the conversion of pyruvate, α-ketoglutarate, and branched-chain α-keto acids. As a result, affected individuals may experience a wide range of symptoms and health problems.

DLD deficiency is associated with various diseases and conditions, including Leigh syndrome, a severe neurological disorder characterized by progressive loss of mental and movement abilities. Additional symptoms may include developmental delay, muscle weakness, and lactic acidosis.

DLD deficiency is listed in various genetic databases and registries, including OMIM (Online Mendelian Inheritance in Man) and the Genetic and Rare Diseases Information Center (GARD). These resources provide scientific articles, references, and additional information on the genetic changes, symptoms, testing, and management of DLD deficiency.

Testing for DLD deficiency may include genetic testing to identify changes in the DLD gene, as well as functional enzyme testing to evaluate DLD enzyme activity. These tests can help confirm a diagnosis and guide treatment and management strategies.

In summary, dihydrolipoamide dehydrogenase deficiency is a rare genetic disorder that affects the function of the DLD enzyme. This deficiency leads to disruptions in key cellular complexes and can result in various health problems and conditions. Understanding the genetic and functional changes associated with this deficiency is essential for diagnosis, management, and research efforts aimed at improving the health and well-being of affected individuals.

Leigh syndrome

Leigh syndrome is a genetic disorder related to the deficiency of the DLD gene, which encodes an essential component of the dihydrolipoamide dehydrogenase (DLD) enzyme complex. This enzyme is involved in the pyruvate dehydrogenase complex, and any changes or mutations in the DLD gene can lead to cellular dysfunction.

Leigh syndrome is listed in various scientific databases and resources, including OMIM (Online Mendelian Inheritance in Man) and PubMed. These resources provide additional information on the genetic changes, clinical presentation, and testing options for Leigh syndrome.

Leigh syndrome is characterized by progressive neurological deterioration and can lead to severe disability or death. It is one of the many diseases associated with mitochondrial dysfunction. Mitochondria are essential organelles in cells responsible for energy production. Dysfunction in mitochondrial function can result in a wide range of clinical conditions.

There are several variants of Leigh syndrome, each associated with different genetic changes in the DLD gene or other genes involved in mitochondrial function. Genetic testing is often used to diagnose Leigh syndrome and identify the specific genetic variant causing the condition.

Research articles and scientific publications provide valuable insights into the function and role of the DLD gene in Leigh syndrome. These articles can be found in scientific journals and databases like PubMed. The Human Gene Mutation Database (HGMD) and the Online Mendelian Inheritance in Man (OMIM) catalog this information and provide references to relevant articles.

For individuals and families affected by Leigh syndrome, there are support organizations and registries that provide resources, information, and assistance. These organizations can offer guidance on managing the disease, accessing medical care, and connecting with other individuals or families facing similar challenges.
