Labcorp Genetics (formerly Invitae), Labcorp RCV003603226 SCV004376156 uncertain significance Argininosuccinate lyase deficiency 2022-10-25 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 164 of the ASL protein (p.Ala164Pro). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with a positive newborn screening result for ASL-related disease (PMID: 32778825). 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. 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.
