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]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.3724A>G (p.N1242D) alteration is located in exon 21 (coding exon 21) of the SCN11A gene. This alteration results from a A to G substitution at nucleotide position 3724, causing the asparagine (N) at amino acid position 1242 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 1242 of the SCN11A protein (p.Asn1242Asp). This variant is present in population databases (rs769151002, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with SCN11A-related conditions. ClinVar contains an entry for this variant (Variation ID: 474722). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt SCN11A protein function with a negative predictive value of 80%. 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. -
