Invitae | RCV000815768 | SCV000956238 | uncertain significance | Epilepsy, X-linked 1, with variable learning disabilities and behavior disorders | 2018-12-03 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine with glutamic acid at codon 440 of the SYN1 protein (p.Gly440Glu). The glycine residue is moderately conserved and there is a moderate physicochemical difference between glycine and glutamic acid. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with SYN1-related disease. 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: "Possibly 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. |
