This sequence change affects codon 1573 of the SCN5A mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the SCN5A protein. This variant is present in population databases (rs754221948, ExAC 0.001%). This variant has been reported in an individual with Brugada syndrome and in a proband and her father, both with conduction disturbances (PMID: 19843921, 27668095). It has also been reported in an individual affected with bundle branch re-entrant ventricular tachycardia (PMID: 29759522). ClinVar contains an entry for this variant (Variation ID: 263423). Experimental studies have shown that this silent change causes a deleterious effect on SCN5A mRNA splicing (PMID: 23425522). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
