KCNQ1

KCNQ1 is a gene that provides instructions for making a protein called a potassium ion channel. These channels are important for regulating electrical signals in heart cells, helping to control the heart's rhythm. When KCNQ1 doesn’t function properly due to mutations, it can lead to health issues like long QT syndrome, a condition that can cause irregular heartbeats. This can increase the risk of fainting, seizures, or even sudden death. Understanding KCNQ1 is essential for studying cardiac health and developing treatments for related heart conditions.
