Noonans syndrom

Noonan syndrome is a condition that affects many areas of the body. It is characterized by mildly unusual facial features, short stature, heart defects, bleeding problems, skeletal malformations, and many other signs and symptoms A number of genetic mutations can result in Noonan syndrome. The condition may be inherited from a person's parents or occur as a new mutation during early development. It is autosomal dominant. Noonan syndrome is a type of RASopathy, the underlying mechanism for which involves a problem with a cell signaling pathway Noonan syndrome can develop because of a new mutation in children who don't have a genetic predisposition for the disorder (de novo). Risk factors. A parent with Noonan syndrome has a 50 percent chance (one chance in two) of passing the defective gene on to his or her child Noonan syndrome is a condition that affects many areas of the body. It is characterized by mildly unusual facial characteristics, short stature, heart defects, bleeding problems, skeletal malformations, and many other signs and symptoms.
