Invitae RCV000169398 SCV000946438 pathogenic Glutaric aciduria, type 1 2023-10-30 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 402 of the GCDH protein (p.Arg402Gln). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with Glutaric acidemia type 1 (PMID: 15505393, 24332224). ClinVar contains an entry for this variant (Variation ID: 189011). 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%. This variant disrupts the p.Arg402 amino acid residue in GCDH. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 8900227, 10649503, 11073722, 20732827, 28352331, 28438223). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
