Description

This variant has not been reported in the literature in individuals with an ATP1A3-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with arginine at codon 304 of the ATP1A3 protein (p.Gly304Arg). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and arginine. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C15"). In summary, this variant has uncertain impact on ATP1A3 function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies.
