Labcorp Genetics (formerly Invitae), Labcorp RCV002613010 SCV002954542 uncertain significance Neuropathy, hereditary sensory and autonomic, type 2A; Generalized epilepsy with febrile seizures plus, type 7 2022-06-14 criteria provided, single submitter clinical testing This sequence change replaces tyrosine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 63 of the SCN9A protein (p.Tyr63Asn). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SCN9A-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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.
