Labcorp Genetics (formerly Invitae), Labcorp RCV001959462 SCV002257043 uncertain significance Early-onset Parkinson disease 20; Developmental and epileptic encephalopathy, 53 2022-11-15 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 1466276). 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 0.006%). This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 1558 of the SYNJ1 protein (p.Asn1558Ser).
