Description

The p.R8Q variant (also known as c.23G>A), located in coding exon 1 of the SCN5A gene, results from a G to A substitution at nucleotide position 23. The arginine at codon 8 is replaced by glutamine, an amino acid with some highly similar properties. This amino acid position is not 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.
