Summaries for OXCT1 Gene

Entrez Gene Summary for OXCT1 Gene

  • This gene encodes a member of the 3-oxoacid CoA-transferase gene family. The encoded protein is a homodimeric mitochondrial matrix enzyme that plays a central role in extrahepatic ketone body catabolism by catalyzing the reversible transfer of coenzyme A from succinyl-CoA to acetoacetate. Mutations in this gene are associated with succinyl CoA:3-oxoacid CoA transferase deficiency. [provided by RefSeq, Jul 2008]

GeneCards Summary for OXCT1 Gene

OXCT1 (3-Oxoacid CoA Transferase 1) is a Protein Coding gene. Diseases associated with OXCT1 include succinyl coa:3-oxoacid coa transferase deficiency.
