Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong
The NM_001365536.1(SCN9A):c.5956A>G(p.Ser1986Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000515 in 1,592,248 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 17/22 in silico tools predict a benign 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. S1986N) has been classified as Uncertain significance.

not provided Uncertain:3
The SCN9A c.5923A>G; p.Ser1975Gly variant (rs200785571), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 471159). This variant is found in the non-Finnish European population with an allele frequency of 0.007% (8/120,012 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.279). Due to limited information, the clinical significance of this variant is uncertain at this time. -

Inborn genetic diseases Uncertain:1
The c.5923A>G (p.S1975G) alteration is located in exon 27 (coding exon 26) of the SCN9A gene. This alteration results from a A to G substitution at nucleotide position 5923, causing the serine (S) at amino acid position 1975 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Generalized epilepsy with febrile seizures plus, type 7;C2752089:Neuropathy, hereditary sensory and autonomic, type 2A Uncertain:1
This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 1975 of the SCN9A protein (p.Ser1975Gly). This variant is present in population databases (rs200785571, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with SCN9A-related conditions. ClinVar contains an entry for this variant (Variation ID: 471159). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Not Available". The glycine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
