The disorder is characterized by a wide spectrum of symptoms and physical features that vary greatly in range and severity. In many affected individuals, associated abnormalities include a distinctive facial appearance; a broad or webbed neck;

Individuals with the disorder typically reach their adult height by the end of the second decade of life. Growth patterns are influenced by the molecular genetic cause of NS.

What is the long term outcome of noonan syndrome?
Studies generally suggest that long-term outcome depends largely on the presence and severity of congenital heart defects. Death in affected people has been frequently associated with the presence of complex left ventricular disease. [7] Studies have indicated that people with Noonan syndrome have a 3-fold higher mortality rate than those in the general population. [8] [9]

Does noonan syndrome need special help?
Some children with Noonan syndrome may need special help in school, including for example, an individualized educational program (IEP). [3] Treatment for bleeding problems depends on the cause. [3] . Growth hormone (GH) therapy can increase the rate at which a child with Noonan syndrome grows in most cases.
Is noonan syndrome inherited?
It is typically inherited in an autosomal dominant manner, but many cases are due to a new mutation and are not inherited from either parent. Treatment depends on the symptoms present in each person. [3] Noonan syndrome belongs to a group of related conditions called the RASopathies.
