Labcorp Genetics (formerly Invitae), Labcorp RCV001222410 SCV001394508 uncertain significance Early-onset Parkinson disease 20; Developmental and epileptic encephalopathy, 53 2022-07-12 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 909 of the SYNJ1 protein (p.Ile909Thr). This variant is present in population databases (rs753305423, gnomAD 0.01%). 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: 950655). 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: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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.
