Entrez Gene Summary for COQ2 Gene

  • This gene encodes an enzyme that functions in the final steps in the biosynthesis of CoQ (ubiquinone), a redox carrier in the mitochondrial respiratory chain and a lipid-soluble antioxidant. This enzyme, which is part of the coenzyme Q10 pathway, catalyzes the prenylation of parahydroxybenzoate with an all-trans polyprenyl group. Mutations in this gene cause coenzyme Q10 deficiency, a mitochondrial encephalomyopathy, and also COQ2 nephropathy, an inherited form of mitochondriopathy with primary renal involvement. [provided by RefSeq, Oct 2009]

GeneCards Summary for COQ2 Gene

COQ2 (Coenzyme Q2 4-Hydroxybenzoate Polyprenyltransferase) is a Protein Coding gene. Diseases associated with COQ2 include coenzyme q10 deficiency, primary, 1 and mitochondrial encephalomyopathy. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include 4-hydroxybenzoate decaprenyltransferase activity and 4-hydroxybenzoate nonaprenyltransferase activity.

UniProtKB/Swiss-Prot for COQ2 Gene

  • Catalyzes the prenylation of para-hydroxybenzoate (PHB) with an all-trans polyprenyl group. Mediates the second step in the final reaction sequence of coenzyme Q (CoQ) biosynthesis, which is the condensation of the polyisoprenoid side chain with PHB, generating the first membrane-bound Q intermediate.

  • Coenzyme Q10 deficiency, primary, 1 (COQ10D1) [MIM:607426]: An autosomal recessive disorder with variable manifestations consistent with 5 major phenotypes. The phenotypes include an encephalomyopathic form with seizures and ataxia; a multisystem infantile form with encephalopathy, cardiomyopathy and renal failure; a predominantly cerebellar form with ataxia and cerebellar atrophy; Leigh syndrome with growth retardation; and an isolated myopathic form. {ECO:0000269 PubMed:16400613, ECO:0000269 PubMed:17855635}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Multiple system atrophy 1 (MSA1) [MIM:146500]: A progressive neurodegenerative disorder clinically characterized by parkinsonism, cerebellar ataxia, and autonomic, urogenital, and pyramidal dysfunction in various combinations. Pathologically, it is characterized by degeneration of striatonigral and olivopontocerebellar structures, and glial cytoplasmic inclusions that consist of abnormally phosphorylated alpha-synuclein or tau. {ECO:0000269 PubMed:23758206}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
