Genes affected

PCCA (HGNC:8653): (propionyl-CoA carboxylase subunit alpha) The protein encoded by this gene is the alpha subunit of the heterodimeric mitochondrial enzyme Propionyl-CoA carboxylase. PCCA encodes the biotin-binding region of this enzyme. Mutations in either PCCA or PCCB (encoding the beta subunit) lead to an enzyme deficiency resulting in propionic acidemia. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, May 2010]

Likely pathogenic, criteria provided, single submitter	clinical testing	Counsyl	Feb 14, 2018	- -
Likely pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Oct 07, 2020	In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant has been reported to affect PCCA protein function (PMID: 12385775). This variant has been observed in individual(s) with propionic acidemia (PMID: 10780784, 12385775, 27825584). ClinVar contains an entry for this variant (Variation ID: 203878). This variant is also known as c.1816G>C (p.Gly606Arg) in the literature. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with arginine at codon 631 of the PCCA protein (p.Gly631Arg). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and arginine. -
