Invitae RCV000533677 SCV000648982 uncertain significance Emery-Dreifuss muscular dystrophy 5, autosomal dominant 2016-12-08 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid with valine at codon 2783 of the SYNE2 protein (p.Glu2783Val). The glutamic acid residue is weakly conserved and there is a moderate physicochemical difference between glutamic acid and valine. This variant is present in population databases (rs773304417, ExAC 0.001%) but has not been reported in the literature in individuals with a SYNE2-related disease. 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may alter RNA splicing, but this prediction has not been confirmed by published transcriptional studies. In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance.
