Genes affected

SCN10A (HGNC:10582): (sodium voltage-gated channel alpha subunit 10) The protein encoded by this gene is a tetrodotoxin-resistant voltage-gated sodium channel alpha subunit. The properties of the channel formed by the encoded transmembrane protein can be altered by interaction with different beta subunits. This protein may be involved in the onset of pain associated with peripheral neuropathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Gln1021*) in the SCN10A gene. It is expected to result in an absent or disrupted protein product. However, the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in SCN10A cause disease. This variant is present in population databases (rs751252167, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with SCN10A-related conditions. ClinVar contains an entry for this variant (Variation ID: 463245). 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Q1021* variant (also known as c.3061C>T), located in coding exon 16 of the SCN10A gene, results from a C to T substitution at nucleotide position 3061. This changes the amino acid from a glutamine to a stop codon within coding exon 16. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. However, the evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear. -
