Glutaric aciduria, type 1 Pathogenic:7
- -
This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 119 of the GCDH protein (p.Ser119Leu). This variant is present in population databases (no rsID available, gnomAD 0.02%). This missense change has been observed in individual(s) with glutaric acidemia and glutaric acidemia type 1 (PMID: 11015709, 15505393, 17188916, 28389991). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 288248). 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 expected to disrupt GCDH protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -
The GCDH c.356C>T (p.Ser119Leu) variant has been reported in at least five studies and is found in a total of seven probands with glutaric acidemia including two in a homozygous state and five in a compound heterozygous state, which includes three siblings (Busquets et al. 2000; Christensen et al. 2004; Korman et al. 2007; Devi et al. 2016; Mosaeilhy et al. 2017). Control data are unavailable for this variant, which is reported at a frequency of 0.000012 in the Total population of the Genome Aggregation Database. In vitro analysis in proband fibroblasts determined that the p.Ser119Leu variant is associated with significantly reduced GCDH activity ranging from zero to five percent of controls (Busquets et al. 2000; Christensen et al. 2004). Based on the evidence, the p.Ser119Leu variant is classified as pathogenic for glutaric acidemia. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -

Variant summary: GCDH c.356C>T (p.Ser119Leu) results in a non-conservative amino acid change located in the Acyl-CoA dehydrogenase/oxidase, N-terminal domain (IPR013786) 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 1.2e-05 in 251426 control chromosomes (gnomAD). c.356C>T has been reported in the literature in multiple individuals affected with Glutaric Acidemia Type 1 (examples: Busquets_2000, Christensen_2004, Radha Rama_2016, Moseilhy_2017). 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: 28389991, 26071121, 11015709, 15505393). ClinVar contains an entry for this variant (Variation ID: 288248). Based on the evidence outlined above, the variant was classified as pathogenic. -
