Description

The p.I759V variant (also known as c.2275A>G), located in coding exon 14 of the SCN5A gene, results from an A to G substitution at nucleotide position 2275. The isoleucine at codon 759 is replaced by valine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
