Mutations associated with SCN5A, which encodes the major cardiac sodium channel, influence impulse conduction and are associated with arrhythmia disorders. Here, the authors identify an evolutionary conserved, super enhancer-like, regulatory cluster downstream of SCN5A and show that it controls the chromatin architecture of the locus and Scn5a expression.
