SCN5A

SCN5A is a gene that provides instructions for making a protein involved in the function of sodium channels in heart cells. These channels help control the flow of sodium ions, which are crucial for generating and spreading electrical signals that regulate the heartbeat. Mutations in the SCN5A gene can lead to various heart conditions, such as Long QT syndrome, Brugada syndrome, and idiopathic ventricular fibrillation. These conditions can disrupt the normal rhythm of the heart, potentially leading to serious complications. Understanding SCN5A is important for diagnosing and managing heart-related health issues.
