Labcorp Genetics (formerly Invitae), Labcorp RCV002780286 SCV003019265 uncertain significance Hereditary spastic paraplegia 3A 2024-12-16 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 403 of the ATL1 protein (p.Arg403Gln). This variant is present in population databases (no rsID available, gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ATL1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1980592). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ATL1 protein function. This variant disrupts the p.Arg403 amino acid residue in ATL1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 30008475). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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.
