Symptoms of Noonan Syndrome

Noonan syndrome is a genetic condition that affects normal development in many body parts. Signs may occur in different ways, such as developmental delays, physical issues, heart defects, short stature, or abnormal facial features. A genetic defect is the main cause of Noonan syndrome. Children tend to inherit these affected genes from their parents. Fortunately, there are a few options to help manage the symptoms. Below are some typical symptoms of Noonan syndrome that you need to know.

1Facial Features

People with Noonan syndrome are characterized by some facial features that are clearer in young children and infants. These include:

– Ears: rotated backward and low-set

– Eyes: down-slanting and wide-set with droopy lids. Green or pale blue irises

– Mouth: a deep groove between the mouth and the nose, wide peaks in the upper lip

– Nose: bulbous tip, wide base, depressed at the top

– Head: large forehead and low hairline

– Face: expressionless and droopy

These facial features may change with age and become subtler in adults. [1]
