Description

The p.P1155S variant (also known as c.3463C>T), located in coding exon 18 of the SCN5A gene, results from a C to T substitution at nucleotide position 3463. The proline at codon 1155 is replaced by serine, an amino acid with 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.
