Description

The p.K718R variant (also known as c.2153A>G), located in coding exon 13 of the SCN8A gene, results from an A to G substitution at nucleotide position 2153. The lysine at codon 718 is replaced by arginine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
