KCNJ6 is a gene that provides instructions for making a protein known as a potassium ion channel. This channel is important for regulating the flow of potassium ions in and out of cells, which helps maintain the electrical balance necessary for various cellular functions, including nerve signaling and muscle contraction. Mutations in the KCNJ6 gene can lead to health issues, such as dystonia, a movement disorder characterized by involuntary muscle contractions. Understanding KCNJ6 is crucial for researchers studying the underlying mechanisms of such disorders and developing potential treatments.
