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.

Weight and length at birth are usually normal, but growth slows over time
Noonan syndrome with multiple lentigines (NSML) which is part of a group called Ras/MAPK pathway syndromes, is a rare autosomal dominant, multisystem disease caused by a mutation in the protein tyrosine phosphatase, non-receptor type 11 gene () Noonan syndrome was first recognized as a unique entity in 1963 when Noonan and Ehmke described a series of patients with unusual facies and multiple malformations, including congenital heart disease. These patients were previously thought to have a form of Turner syndrome, with which Noonan syndrome shares numerous clinical features .
