Invitae | RCV002904568 | SCV003258927 | uncertain significance | Early-onset Parkinson disease 20; Developmental and epileptic encephalopathy, 53 | 2022-02-02 | 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. This variant disrupts the p.Arg258 amino acid residue in SYNJ1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 23804563, 23804577, 24816432). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C25"). This missense change has been observed in individual(s) with clinical features of SYNJ1-related conditions (Invitae). This variant is present in population databases (no rsID available, gnomAD 0.006%). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 258 of the SYNJ1 protein (p.Arg258Trp). |
