Invitae RCV000534246 SCV000649357 uncertain significance Neuropathy, hereditary sensory and autonomic, type 2A; Generalized epilepsy with febrile seizures plus, type 7 2017-03-07 criteria provided, single submitter clinical testing 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 an SCN9A-related disease. This sequence change replaces aspartic acid with valine at codon 1666 of the SCN9A protein (p.Asp1666Val). The aspartic acid residue is highly conserved and there is a large physicochemical difference between aspartic acid and valine. 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.
