Description

The p.P79A variant (also known as c.235C>G), located in coding exon 1 of the SCN5A gene, results from a C to G substitution at nucleotide position 235. The proline at codon 79 is replaced by alanine, 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.
