Several other genes have been identified in association with Brugada syndrome. Some are responsible for other proteins that form part of the sodium channel, known as sodium channel β subunits (SCN1B, SCN2B, SCN3B) while others form different types of sodium channel (SCN10A). Some genes encode ion channels that carry calcium or potassium ions (CACNA1C, CACNB2, KCND3, KCNE3, KCNJ8), while others generate proteins that interact with ion channels. (GPD1L, PKP2, MOG1, FGF12). Another gene associated with this condition is RRAD. The genes associated with Brugada syndrome and their description include:
