OnCo

SDHA (Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial) is a gene that drives cell growth when it is altered. The public catalogues list it as an oncogene driver and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Neuroendocrine tumours, Renal cell carcinoma, Hepatocellular carcinoma and 5 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

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). SDH also oxidises malate to the non-canonical enol form of oxaloacetate, enol-oxaloacetate. Enol-oxaloacetate, which is a potent inhibitor of the succinate dehydrogenase activity, is further isomerised into keto-oxaloacetate. Can act as a tumour suppressor. Location: Mitochondrion inner membrane (UniProt). Locus 5p15.33 (HGNC).
