Brugada Syndrome Disease Phenotype Explained in Apparently Benign Sodium Channel Mutations

Abstract

Taken together, we have shown how apparently benign SCN5A BrS mutations can lead to the ECG abnormalities seen in patients with BrS through an induced defect that is only present when the mutations are coexpressed with WT channels. Our work has implications for risk management and stratification for some SCN5A-implicated BrS patients.
