Invitae RCV000472022 SCV000548733 uncertain significance Developmental and epileptic encephalopathy, 9 2019-04-29 criteria provided, single submitter clinical testing In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a PCDH19-related disease. This sequence change replaces valine with glutamic acid at codon 493 of the PCDH19 protein (p.Val493Glu). The valine residue is highly conserved and there is a moderate physicochemical difference between valine and glutamic acid.
