Invitae RCV000797091 SCV000936631 uncertain significance Neuropathy, hereditary sensory and autonomic, type 2A; Generalized epilepsy with febrile seizures plus, type 7 2018-09-20 criteria provided, single submitter clinical testing This variant is present in population databases (rs200501298, ExAC 0.002%). This sequence change replaces glutamic acid with aspartic acid at codon 1465 of the SCN9A protein (p.Glu1465Asp). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and aspartic acid. This variant has not been reported in the literature in individuals with SCN9A-related disease. 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. 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 and their clinical significance is uncertain.
