Overview

Temple-Baraitser syndrome (also called DOORS syndrome or Deafness, Onychodystrophy, Osteodystrophy, mental Retardation, and Seizures syndrome) is a rare genetic condition that affects brain development and several other parts of the body. It is caused by changes (mutations) in the KCNK4 gene, which plays an important role in how brain cells communicate with each other. The condition is present from birth and affects children in many different ways. The most common features include intellectual disability (ranging from mild to severe), absent or very small fingernails and toenails, abnormal bone development in the fingers and toes, hearing loss, and seizures that can be difficult to control. Some children also have distinctive facial features, feeding difficulties in infancy, and problems with movement and coordination. The severity of symptoms can vary quite a bit from one person to another, even among people with the same genetic change. There is currently no cure for Temple-Baraitser syndrome. Treatment focuses on managing individual symptoms. This may include anti-seizure medications, hearing aids or cochlear implants, physical therapy, occupational therapy, speech therapy, and special education support. A team of different specialists usually works together to provide the best care. With the right support, many children can make meaningful developmental progress, though most will need lifelong assistance.
