Description

The c.4221C>T variant (also known as p.A1407A), located in coding exon 22 of the SCN5A gene, results from a C to T substitution at nucleotide position 4221. This nucleotide substitution does not change the amino acid at codon 1407. This nucleotide position is poorly conserved in available vertebrate species. In silico splice site analysis for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
