Genes affected
GCDH (HGNC:4189): (glutaryl-CoA dehydrogenase) The protein encoded by this gene belongs to the acyl-CoA dehydrogenase family. It catalyzes the oxidative decarboxylation of glutaryl-CoA to crotonyl-CoA and CO(2) in the degradative pathway of L-lysine, L-hydroxylysine, and L-tryptophan metabolism. It uses electron transfer flavoprotein as its electron acceptor. The enzyme exists in the mitochondrial matrix as a homotetramer of 45-kD subunits. Mutations in this gene result in the metabolic disorder glutaric aciduria type 1, which is also known as glutaric acidemia type I. Alternative splicing of this gene results in multiple transcript variants. A related pseudogene has been identified on chromosome 12. [provided by RefSeq, Mar 2013]

Glutaric aciduria, type 1 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Aug 19, 2023 | This sequence change creates a premature translational stop signal (p.Gln251*) in the GCDH gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GCDH are known to be pathogenic (PMID: 10699052, 11854167, 16602100). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with GCDH-related conditions. ClinVar contains an entry for this variant (Variation ID: 577874). For these reasons, this variant has been classified as Pathogenic. - |
