This biomarker is also known as:
  • Propanoyl-CoA:carbon dioxide ligase subunit alpha,
  • EC,
  • propanoyl-CoA:carbon dioxide ligase alpha subunit,
  • propionyl CoA carboxylase, alpha polypeptide,
  • PCCase subunit alpha,
  • PCCase alpha subunit,

  • propionyl Coenzyme A carboxylase, alpha polypeptide,

View in BioMuta


PCCA, or propionyl CoA carboxylase, alpha polypeptide, is the alpha subunit of the heterodimeric mitochondrial enzyme Propionyl-CoA carboxylase. The beta subunit is PCCB. The enzyme deficiency propionic acidemia results from mutations in either PCCA or PCCB. Several isoforms for this gene have been identified, coded by multiple transcript variants.
