Labcorp Genetics (formerly Invitae), Labcorp RCV003604919 SCV004452752 uncertain significance Argininosuccinate lyase deficiency 2023-04-24 criteria provided, single submitter clinical testing 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. 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 ASL protein function. This missense change has been observed in individual(s) with a positive newborn screening result for ASL-related disease (Invitae). This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change replaces leucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 49 of the ASL protein (p.Leu49Met).
