Pallister-Hall syndrome can affect of many parts of the body. Common signs include extra fingers and/or toes and extra skin between the fingers or toes. People with the syndrome may have an abnormal growth in the brain called a hypothalamic hamartoma. Hypothalamic hamartomas often cause no symptoms. Rarely, infants with hypothalamic hamartomas develop serious hormone problems or seizures. Other signs of Pallister-Hall syndrome include bifid epiglottis (a malformation of the airway), an obstruction of the anal opening, and kidney abnormalities. The severity of Pallister-Hall syndrome can be mild to severe, however only a small percentage of people have serious complications. Pallister-Hall syndrome is caused by a mutation in the GLI3 gene. The mutation can be inherited from an affected parent, or can occur for the first time in a family due to a new mutation.
