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]

Variant summary: GCDH c.1060G>A (p.Gly354Ser) results in a non-conservative amino acid change located in the acyl-CoA dehydrogenase/oxidase C-terminal domain (IPR009075) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 250574 control chromosomes (gnomAD). c.1060G>A has been reported in the literature in multiple individuals (both homozygous and compound heterozygous) affected with Glutaric Acidemia Type 1 (examples: Janssen_2014, Schartz_1998). These data indicate that the variant is very likely to be associated with disease. The following publications have been ascertained in the context of this evaluation (PMID: 26674492, 9600243). ClinVar contains an entry for this variant (Variation ID: 188946). Based on the evidence outlined above, the variant was classified as pathogenic. -

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 354 of the GCDH protein (p.Gly354Ser). This variant is present in population databases (rs768925619, gnomAD 0.0009%). This missense change has been observed in individual(s) with glutaric aciduria type I (PMID: 9600243, 16377226, 26656312). ClinVar contains an entry for this variant (Variation ID: 188946). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt GCDH protein function. For these reasons, this variant has been classified as Pathogenic. -
