Brugada syndrome is a heterogeneous heart rhythm disorder characterized by an atypical right bundle block pattern with ST-segment elevation and T-wave inversion in the right precordial leads. Loss-of-function mutations in SCN5A encoding the cardiac sodium channel Na(V)1.5 are associated with Brugada syndrome. We found novel mutations in SCN5A in 2 different families diagnosed with Brugada syndrome and investigated how those affected Na(V)1.5 channel function.
