Invitae | RCV002796615 | SCV003199489 | uncertain significance | Early-onset Parkinson disease 20; Developmental and epileptic encephalopathy, 53 | 2022-05-24 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 1438 of the SYNJ1 protein (p.Gly1438Ser). This variant has not been reported in the literature in individuals affected with SYNJ1-related conditions. 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. |
