Invitae RCV001210497 SCV001381987 uncertain significance Early-onset Parkinson disease 20; Developmental and epileptic encephalopathy, 53 2022-12-07 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 not expected to disrupt SYNJ1 protein function. ClinVar contains an entry for this variant (Variation ID: 940831). This missense change has been observed in individual(s) with a developmental disorder (PMID: 28135719). This variant is present in population databases (rs377719553, gnomAD 0.002%). This sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 662 of the SYNJ1 protein (p.Asn662Asp).
