KCNQ1 gene

The KCNQ1 gene provides instructions for creating a protein that forms part of potassium channels in cells. These channels are crucial for regulating the flow of potassium ions, which help control the heart's rhythm and other electrical activities in the body. Mutations in the KCNQ1 gene can lead to health issues, notably Long QT Syndrome, a condition that can cause irregular heartbeats and increase the risk of sudden cardiac events. Understanding this gene is important for both genetics and cardiac health.
