Succinate dehydrogenase (SDH)–deficient gastrointestinal stromal tumor (GIST) is a subset of wild-type GIST that constitutes approximately 10% of gastric GISTs. Succinate dehydrogenase (SDH) deficiency is a rare autosomal recessive neurometabolic disorder that causes brain insult, neurodevelopmental delay, exercise intolerance, and cardiomyopathy. Trevisson E, DiMauro S, Navas P, Salviati L. Curr Opin Neurol. —Partial succinate dehydrogenase deficiency (15% to 50% of normal reference enzyme activity) in skeletal muscle causes mitochondrial myopathy with various symptoms, for example, brain involvement, cardiomyopathy, and/or exercise intolerance. Epilepsy is present in about half of affected individuals and is more common in adults. J Clin Invest. What is the prognosis of a genetic condition? This enzyme is involved in the breakdown of a chemical that transmits signals in the brain (neurotransmitter) called gamma-amino butyric acid (GABA). Abstract. Fifteen per cent of pheochromocytoma and paraganglioma (PHEO/PGL) are associated with germline SDH mutation, and therefore SDH-deficient. Childs Nerv Syst. Eur J Paediatr Signs and symptoms of this condition usually first appear shortly after birth, and they can vary widely among affected individuals. 2003;54 Suppl Pearl PL, Gibson KM, Acosta MT, Vezina LG, Theodore WH, Rogawski MA, Novotny This site needs JavaScript to work properly. One hundred eight muscle biopsies were evaluated from patients with suspected mitochondrial myopathies by qualitative histochemical analysis and quantitative biochemical analyses of respiratory-chain enzymes using standard methodologies. GABA controls the movements of humans, and when it is imbalanced, major neurological abnormalities occur. Jakobs C, Grompe M, Gibson KM. Jakobs C. Significant behavioral disturbances in succinic semialdehyde The deficiency may be isolated or may coexist with other respiratory-chain enzyme defects. 2001 Sep;116(3):326-30. doi: 10.1309/WATB-W4QV-NA53-B9MY. 2004;8(5):261-5. Review. Gibson KM, Gupta M, Pearl PL, Tuchman M, Vezina LG, Snead OC 3rd, Smit LM, Isolated mitochondrial myopathy associated with muscle coenzyme Q10 deficiency. A shortage (deficiency) of succinic semialdehyde dehydrogenase leads to an increase in the amount of GABA and a related molecule called gamma-hydroxybutyrate (GHB) in the body, particularly the brain and spinal cord (central nervous system). Variations of muscle mitochondrial creatine kinase activity in mitochondrial diseases. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. Rollins S, Prayson RA, McMahon JT, Cohen BH. It is unclear how an increase in GABA and GHB causes developmental delay, seizures, and other signs and symptoms of succinic semialdehyde dehydrogenase deficiency.

It is counterintuitive that metabolic defects reducing ATP production can cause, rather than protect from, cancer. 3:117. doi: 10.3389/fonc.2013.00117 Most patients have germline mutations in an SDH gene Symptoms of PDC deficiency include signs of metabolic dysfunction such as extreme tiredness (lethargy), poor feeding, and rapid breathing (tachypnea). What does it mean if a disorder seems to run in my family? Myopathology of Adult and Paediatric Mitochondrial Diseases. The most common behavioral problems associated with this condition are sleep disturbances, hyperactivity, difficulty maintaining attention, and anxiety. This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. Gordon N. Succinic semialdehyde dehydrogenase deficiency (SSADH) Review. semialdehyde dehydrogenase deficiency. Birch-Machin MA, Marsac C, Ponsot G, Parfait B, Taylor RW, Rustin P, Munnich A. Biochem Biophys Res Commun. What are the different ways in which a genetic condition can be inherited? 1996 Mar 7;220(1):57-62. doi: 10.1006/bbrc.1996.0356. SdhB mutations can lead to tumorogenesis in chromaffin cells, causing a class of tumors known as succinate dehydrogenase deficient including hereditary paraganglioma and hereditary pheochromocytoma, succinate dehydrogenase deficient renal carcinoma and succinate dehydrogenase deficient gastrointestinal stromal tumor (GIST). Remarkably, immunohistochemistry for SDHB becomes negative whenever there is bi‐alleic inactivation of any component of SDH, which is very rare in the absence of syndromic disease. GABA is synthesized in a single step from its precursor glutamate by glutamic acid decarboxylase. Biol Succinate dehydrogenase (SDH) plays such an important role in the mitochondria, being both part of the respira-tory chain and the Krebs cycle, that for a long time any severe deficiency of this enzyme was regarded as being incompatible with life [1]. Mutation of a nuclear succinate dehydrogenase gene results in mitochondrial respiratory chain deficiency. Objectives: The latter is often but not always linked to bi-allelic inactivation of SDH subunit genes, particularly SDHA.

A distinct mechanism of oncogenesis seen in approximately 40% of RTK-wild type GIST is deficiency in the mitochondrially located tumor suppressor complex succinate dehydrogenase (SDH).

Pearl PL, Novotny EJ, Acosta MT, Jakobs C, Gibson KM. mutations in patients with SSADH deficiency. GABA is metabolized by successive transamination and oxidation to yield succinic semialdehyde and succinic acid respectively via the catalyzing effects of GABA transaminase. Partial succinate dehydrogenase deficiency (15% to 50% of normal reference enzyme activity) in skeletal muscle causes mitochondrial myopathy with various symptoms, for example, brain involvement, cardiomyopathy, and/or exercise intolerance. In 2 sibs with complex II mitochondrial respiratory chain deficiency (252011) presenting as Leigh syndrome (256000), Bourgeron et al. Background: Gibson KM. Epub 2018 Feb 27.
