COASY protein-associated neurodegeneration

COASY protein-associated neurodegeneration (CoPAN) is an extremely rare inherited brain disorder that belongs to a group of conditions called neurodegeneration with brain iron accumulation (NBIA). In CoPAN, iron builds up abnormally in certain parts of the brain, particularly the globus pallidus, causing progressive damage to nerve cells. The disease is caused by mutations in the COASY gene, which provides instructions for making an enzyme involved in producing coenzyme A (CoA), a molecule essential for many chemical reactions in the body, including energy production. Symptoms typically begin in childhood and include walking difficulties, muscle stiffness (spasticity), involuntary muscle contractions (dystonia), and problems with speech. Over time, affected individuals may develop cognitive decline, difficulty swallowing, and psychiatric symptoms such as depression or obsessive-compulsive behaviors. Brain MRI scans often show a characteristic pattern of iron accumulation. There is currently no cure for CoPAN. Treatment focuses on managing symptoms and improving quality of life. Medications may help control dystonia and spasticity, and supportive therapies such as physical therapy, occupational therapy, and speech therapy play important roles. Research into disease-modifying treatments, including CoA pathway supplementation strategies, is ongoing but still in early stages. Because CoPAN is so rare, much of what is known comes from a small number of reported cases worldwide.
