Labcorp Genetics (formerly Invitae), Labcorp RCV001343499 SCV001537486 uncertain significance Early-onset Parkinson disease 20; Developmental and epileptic encephalopathy, 53 2022-08-10 criteria provided, single submitter clinical testing This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 1128 of the SYNJ1 protein (p.Gln1128Arg). This variant is present in population databases (rs779932426, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with SYNJ1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1039933). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.
