Did you know

The KCNH2 gene, also known as hERG, is essential for heart function. It encodes a protein responsible for potassium ion channels in cardiac cells, crucial for regulating the heart‘s electrical activity. Mutations in the KCNH2 gene can disrupt these channels, leading to arrhythmias like Long QT syndrome—a heart rhythm disorder that can cause fainting or sudden death. Understanding the KCNH2 gene is critical for diagnosing and managing Long QT syndrome and other heart rhythm abnormalities, potentially leading to improved treatments and outcomes for affected individuals.
