Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BS2

The NM_001349253.2(SCN11A):ā€‹c.88C>Gā€‹(p.Arg30Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000212 in 1,461,828 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R30Q) has been classified as Likely benign.

Genes affected
SCN11A (HGNC:10583): (sodium voltage-gated channel alpha subunit 11) Voltage-gated sodium channels are transmembrane glycoprotein complexes composed of a large alpha subunit with 24 transmembrane domains and one or more regulatory beta subunits. They are responsible for the generation and propagation of action potentials in neurons and muscle. This gene encodes one member of the sodium channel alpha subunit gene family, and is highly expressed in nociceptive neurons of dorsal root ganglia and trigeminal ganglia. It mediates brain-derived neurotrophic factor-evoked membrane depolarization and is a major effector of peripheral inflammatory pain hypersensitivity. Mutations in this gene have been associated with hereditary sensory and autonomic neuropathy type VII and familial episodic pain syndrome-3. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2017]

Hereditary sensory and autonomic neuropathy type 7;C3809899:Familial episodic pain syndrome with predominantly lower limb involvement Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeMar 09, 2022This variant has not been reported in the literature in individuals affected with SCN11A-related conditions. This variant is present in population databases (rs761199291, gnomAD 0.003%). This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 30 of the SCN11A protein (p.Arg30Gly). ClinVar contains an entry for this variant (Variation ID: 968420). 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). -
