RCV002045212 | SCV002296747 | uncertain significance | Neuropathy, hereditary sensory and autonomic, type 2A; Generalized epilepsy with febrile seizures plus, type 7 | 2020-11-23 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals 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: "Deleterious"; 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. This sequence change replaces isoleucine with phenylalanine at codon 196 of the SCN9A protein (p.Ile196Phe). The isoleucine residue is highly conserved and there is a small physicochemical difference between isoleucine and phenylalanine. |
