Labcorp Genetics (formerly Invitae), Labcorp RCV001373332 SCV001570041 uncertain significance Neuropathy, hereditary sensory and autonomic, type 2A; Generalized epilepsy with febrile seizures plus, type 7 2020-06-27 criteria provided, single submitter clinical testing 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 tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with SCN9A-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with glutamine at codon 293 of the SCN9A protein (p.Leu293Gln). The leucine residue is moderately conserved and there is a moderate physicochemical difference between leucine and glutamine.
