What is Noonan Syndrome?
Noonan syndrome (NS) is a genetic condition that affects many areas of the body that occurs in between 1 in 1000 to 1 in 2500 individuals. NS is characterized by mildly unusual facial features, short stature, heart defects, bleeding problems, skeletal malformations, and many other signs and symptoms.
Noonan syndrome is one of a group of related conditions, collectively known as RASopathies. These conditions all have similar signs and symptoms and are caused by changes in the same cell signaling pathway.
There is no cure.
