Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3
The NM_001365536.1(SCN9A):c.1558G>C(p.Gly520Arg) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G520E) has been classified as Uncertain significance.

Genes affected
SCN9A (HGNC:10597): (sodium voltage-gated channel alpha subunit 9) This gene encodes a voltage-gated sodium channel which plays a significant role in nociception signaling. Mutations in this gene have been associated with primary erythermalgia, channelopathy-associated insensitivity to pain, and paroxysmal extreme pain disorder. [provided by RefSeq, Aug 2009]

Generalized epilepsy with febrile seizures plus, type 7;C2752089:Neuropathy, hereditary sensory and autonomic, type 2A Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 30, 2017 | This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with arginine at codon 520 of the SCN9A protein (p.Gly520Arg). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and arginine. 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 do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). - |
