Labcorp Genetics (formerly Invitae), Labcorp RCV001906124 SCV002167204 uncertain significance Early-onset Parkinson disease 20; Developmental and epileptic encephalopathy, 53 2022-11-22 criteria provided, single submitter clinical testing This sequence change replaces asparagine, which is neutral and polar, with threonine, which is neutral and polar, at codon 183 of the SYNJ1 protein (p.Asn183Thr). 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 not expected to disrupt SYNJ1 protein function. ClinVar contains an entry for this variant (Variation ID: 1397387). This variant has not been reported in the literature in individuals affected with SYNJ1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.007%).
