ATP7B gene

The ATP7B gene provides instructions for making a protein involved in transporting copper within the body. This protein helps regulate copper levels by moving excess copper into the liver for storage or removal, preventing toxicity. Proper function of ATP7B is crucial; when it malfunctions or is defective due to mutations, copper can accumulate in tissues, leading to health issues like Wilson’s disease. This condition can cause neurological, liver, and other problems if not managed. Essentially, ATP7B acts as a copper traffic controller, ensuring copper is used and excreted appropriately to maintain balance.
