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]

In summary, this is a rare missense change that is not predicted to affect protein function or cause disease. However, the evidence is insufficient at this time to prove that conclusively. 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies. This variant is present in population databases (no rsID, ExAC 0.002%) but has not been reported in the literature. This sequence change replaces isoleucine with phenylalanine at codon 1555 of the SCN10A protein (p.Ile1555Phe). The isoleucine residue is weakly conserved and there is a small physicochemical difference between isoleucine and phenylalanine. -
