Overview

Noonan syndrome is a genetic condition that affects normal growth and development. It can involve multiple parts of the body, including the heart, facial features, growth, and learning abilities. The condition occurs due to changes in certain genes that control cell growth and development.

Children with Noonan syndrome may have distinctive facial features, short stature, congenital heart defects, or developmental delays. It may be inherited from a parent or occur due to a new genetic change. The condition is usually present from birth, but its signs and symptoms can vary widely among individuals.

Although there is no cure for Noonan syndrome, early diagnosis, regular medical care, and supportive therapies can help manage symptoms and improve quality of life. Many individuals with Noonan syndrome can lead active and fulfilling lives.
