Labcorp Genetics (formerly Invitae), Labcorp RCV001046578 SCV001210485 uncertain significance Arginine:glycine amidinotransferase deficiency 2024-07-10 criteria provided, single submitter clinical testing This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 117 of the GATM protein (p.Lys117Arg). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with GATM-related conditions. ClinVar contains an entry for this variant (Variation ID: 843867). 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 GATM protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
