SCNN1G is a gene that encodes a protein known as the gamma subunit of the epithelial sodium channel (ENaC). This protein plays a crucial role in regulating sodium balance and fluid homeostasis in the body, particularly in the kidneys and lungs. Proper functioning of SCNN1G is essential for maintaining blood pressure and electrolyte levels. Mutations in the SCNN1G gene can lead to various health issues, including Liddle syndrome, a genetic disorder characterized by hypertension and low levels of potassium in the blood. Understanding the function of SCNN1G is important for developing treatments for conditions related to sodium imbalance and hypertension.
