The marked prevalence of succinate dehydrogenase deficiency among patients with respiratory-chain defects and its detection initially by histochemical analysis are important findings. Nat Genet. Approximately 350 people with succinic semialdehyde dehydrogenase deficiency have been reported worldwide. Bouzidi MF, Enjolras N, Carrier H, Vial C, Lopez-Mediavilla C, Burt-Pichat B, Couthon F, Godinot C. Biochim Biophys Acta. As such, SDH activity was thought to be universally required for cell proliferation and survival. RESEARCH ARTICLE Open Access Succinate dehydrogenase deficiency in a PDGFRA mutated GIST Martin G. Belinsky1*, Kathy Q. Cai 2, Yan Zhou3, Biao Luo4, Jianming Pei5, Lori Rink1 and Margaret von Mehren1 Abstract Background: Most gastrointestinal stromal tumors (GISTs) harbor mutually exclusive gain of function mutations in the disorders. The histopathologic assessment of succinate dehydrogenase activity in muscle biopsies of patients with suspected mitochondrial myopathies has focused on the finding of increased staining, usually in ragged-red fibers, rather than on reduced staining. In individuals with the disorder, deficient activity of the SSADH enzyme disrupts the metabolism of gamma-aminobutyric acid (GABA). Succinate dehydrogenase (SDH) deficiency is a rare autosomal recessive neurometabolic disorder that causes brain insult, neurodevelopmental delay, exercise intolerance, and cardiomyopathy. Gonzalez S, Sathyapalan T, Javed Z, Atkin SL. Succinic semialdehyde dehydrogenase deficiency is a disorder that can cause a variety of neurological problems. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Jakobs et al. Signs and symptoms of this condition usually first appear shortly after birth, and they can vary widely among affected individuals. Pyruvate dehydrogenase complex (PDC) deficiency is a type of metabolic disease. Mitochondrial myopathy with succinate dehydrogenase and aconitase deficiency: abnormalities of several iron-sulfur proteins. A 25-month-old boy was referred to our neurometabolic center due to developmental regression after injecting the influenza vaccine when he was 10 months old. Background: Succinate dehydrogenase (SDH)-deficient renal cell carcinoma (RCC) is a recently recognized distinct subtype of RCC in the 2016 World Health Organization classification. 1996 Jun 7;1316(2):61-70. doi: 10.1016/0925-4439(95)00126-3. Bourgeron T, Rustin P, Chretien D, et al. (1983) demonstrated deficiency of the succinic semialdehyde dehydrogenase enzyme in lymphocyte lysates from 2 patients with gamma-hydroxybutyric aciduria. Gibson KM, Gupta M, Pearl PL, Tuchman M, Vezina LG, Snead OC 3rd, Smit LM, Diagnostic yield muscle biopsy in patients with clinical evidence of mitochondrial cytopathy. How are genetic conditions treated or managed? 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. *Department of Anatomical Pathology Douglass Hanly Moir Pathology †Discipline of Pathology, MQ Health Macquarie University, Macquarie Park § Cancer Diagnosis and Pathology Group Kolling Institute of Medical Research ∥ Department of Anatomical Pathology Royal North Shore Hospital NSW Health Pathology St Leonards ‡ Sydney Medical School, The University of Sydney, Sydney, NSW, Australia Pearl PL, Gibson KM, Acosta MT, Vezina LG, Theodore WH, Rogawski MA, Novotny The most common behavioral problems associated with this condition are sleep disturbances, hyperactivity, difficulty maintaining attention, and anxiety. Myopathology of Adult and Paediatric Mitochondrial Diseases. It is an inborn error of metabolism, a condition in which the metabolism (chemical reactions in our body) is affected due … COVID-19 is an emerging, rapidly evolving situation. This enzyme is involved in the breakdown of a chemical that transmits signals in the brain (neurotransmitter) called gamma-amino butyric acid (GABA). Functional SDH deficiency is therefore a … Citation: Belinsky MG, Rink L and von Mehren M (2013) Succinate dehydrogenase deficiency in pediatric and adult gastrointestinal stromal tumors. Hum Mutat. Gibson KM.  |  GABA is a major inhibitory neurotransmitter in the central nervous system. dehydrogenase deficiency in children and adults. 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. SDH-mutated GISTs lack mutations in the proto-oncogene receptor tyrosine kinase (also known as KIT, c-KIT, or CD117) or platelet-derived growth factor receptor α (PDGFR-α). Please enable it to take advantage of the complete set of features! mutations in patients with SSADH deficiency. 3:117. doi: 10.3389/fonc.2013.00117 Effects of Growth Hormone Replacement on Peripheral Muscle and Exercise Capacity in Severe Growth Hormone Deficiency. The deficiency may be isolated or may coexist with other respiratory-chain enzyme defects. Neurol. Mutation of a nuclear succinate dehydrogenase gene results in mitochondrial respiratory chain deficiency. Eur J Paediatr 2003;54 Suppl About half of those affected experience seizures, difficulty coordinating movements (ataxia), decreased reflexes (hyporeflexia), and behavioral problems. Succinate dehydrogenase (SDH)-deficient renal carcinoma has been accepted as a provisional entity in the 2013 International Society of Urological Pathology Vancouver Classification. 2004;8(5):261-5. Review. NLM [5.] Succinate dehydrogenase (SDH)–deficient gastrointestinal stromal tumor (GIST) is a subset of wild-type GIST that constitutes approximately 10% of gastric GISTs. To determine the prevalence of muscle succinate dehydrogenase deficiency among patients with respiratory-chain defects and to determine whether the reduced activity is present histochemically and is comparable to the quantitative reduction found in muscle homogenates. Ann Neurol. Collapse Section Pyruvate dehydrogenase deficiency is characterized by the buildup of a chemical called lactic acid in the body and a variety of neurological problems. GABA is metabolized by successive transamination and oxidation to yield succinic semialdehyde and succinic acid respectively via the catalyzing effects of GABA transaminase. Fifty-two patients had defects in respiratory-chain complexes; of these patients, 12 (23%) had partial deficiencies in succinate dehydrogenase activity either alone or together with reductions in other enzymes. 6:S73-80.
