Labcorp Genetics (formerly Invitae), Labcorp RCV001223988 SCV001396159 uncertain significance Early-onset Parkinson disease 20; Developmental and epileptic encephalopathy, 53 2020-08-31 criteria provided, single submitter clinical testing 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 aspartic acid amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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 has not been reported in the literature in individuals with SYNJ1-related conditions. This variant is present in population databases (rs375352780, ExAC 0.01%). This sequence change replaces glycine with aspartic acid at codon 1544 of the SYNJ1 protein (p.Gly1544Asp). The glycine residue is moderately conserved and there is a moderate physicochemical difference between glycine and aspartic acid.
