There is no single treatment for Noonan syndrome. Treatment focuses on the individual symptoms. Growth hormone has been used successfully to treat short stature in some persons with Noonan syndrome.

The expected outcome depends on the extent and severity of symptoms. Patients can lead normal lives.

• Accumulation of fluid in tissues of body (lymphedema, cystic hygroma)
• Failure to thrive in infants
• Low self-esteem
• Male infertility in those with both testes undescended
• Problems with the structure of the heart
• Short stature
