Noonan syndrome is a genetic disorder that affects many areas of the body. It is caused by a fault in one of several genes, and it can be inherited from one of the childs parents or caused by a new genetic fault that isnt inherited from either parent. The most common features of Noonan syndrome include unusual facial features, such as a broad forehead, drooping eyelids, and a wider-than-usual distance between the eyes, short stature, and congenital heart disease. Other symptoms may include bleeding problems, skeletal malformations, and slow development in walking, talking, or learning new things. The severity of the symptoms can vary greatly, and some people with Noonan syndrome may have normal intelligence. Doctors manage Noonan syndrome by controlling the symptoms and complications, and they may use a growth hormone to treat short height in some people with Noonan syndrome.
