Summaries for SDHA Gene

Entrez Gene Summary for SDHA Gene

  • This gene encodes a major catalytic subunit of succinate-ubiquinone oxidoreductase, a complex of the mitochondrial respiratory chain. The complex is composed of four nuclear-encoded subunits and is localized in the mitochondrial inner membrane. Mutations in this gene have been associated with a form of mitochondrial respiratory chain deficiency known as Leigh Syndrome. A pseudogene has been identified on chromosome 3q29. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2014]

GeneCards Summary for SDHA Gene

SDHA (Succinate Dehydrogenase Complex Flavoprotein Subunit A) is a Protein Coding gene. Diseases associated with SDHA include Mitochondrial Complex Ii Deficiency and Paragangliomas 5. Among its related pathways are Metabolism and Citrate cycle (TCA cycle). Gene Ontology (GO) annotations related to this gene include oxidoreductase activity and oxidoreductase activity, acting on the CH-CH group of donors.

UniProtKB/Swiss-Prot for SDHA Gene

  • Flavoprotein (FP) subunit of succinate dehydrogenase (SDH) that is involved in complex II of the mitochondrial electron transport chain and is responsible for transferring electrons from succinate to ubiquinone (coenzyme Q) (PubMed:24781757). Can act as a tumor suppressor (PubMed:20484225).

  • Mitochondrial complex II deficiency (MT-C2D) [MIM:252011]: A disorder of the mitochondrial respiratory chain with heterogeneous clinical manifestations. Clinical features include psychomotor regression in infants, poor growth with lack of speech development, severe spastic quadriplegia, dystonia, progressive leukoencephalopathy, muscle weakness, exercise intolerance, cardiomyopathy. Some patients manifest Leigh syndrome or Kearns-Sayre syndrome. Note=The disease is caused by mutations affecting the gene represented in this entry. {ECO:0000269 PubMed:12794685}.
  • Leigh syndrome (LS) [MIM:256000]: An early-onset progressive neurodegenerative disorder characterized by the presence of focal, bilateral lesions in one or more areas of the central nervous system including the brainstem, thalamus, basal ganglia, cerebellum and spinal cord. Clinical features depend on which areas of the central nervous system are involved and include subacute onset of psychomotor retardation, hypotonia, ataxia, weakness, vision loss, eye movement abnormalities, seizures, and dysphagia. {ECO:0000269 PubMed:10746566, ECO:0000269 PubMed:24781757, ECO:0000269 PubMed:7550341}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Cardiomyopathy, dilated 1GG (CMD1GG) [MIM:613642]: A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. {ECO:0000269 PubMed:20551992}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Paragangliomas 5 (PGL5) [MIM:614165]: A neural crest tumor usually derived from the chromoreceptor tissue of a paraganglion. Paragangliomas can develop at various body sites, including the head, neck, thorax and abdomen. Most commonly, they are located in the head and neck region, specifically at the carotid bifurcation, the jugular foramen, the vagal nerve, and in the middle ear. {ECO:0000269 PubMed:20484225}. Note=The disease is caused by mutations affecting the gene represented in this entry.
