Noonan syndrome is a disease passed down through families (inherited) that causes abnormal development in many parts of the body. It used to be called Turner-like syndrome.
Causes, incidence, and risk factors
Noonan syndrome is linked to defects in several genes. Problems with the genes cause certain proteins involved in growth and development to become overactive.
Noonan syndrome is an autosomal dominant condition. This means only one parent has to pass down the faulty gene for the baby to have the syndrome. However, some cases may not be inherited.
