Noonan Syndrome

Individuals with Noonan syndrome (NS) have facial dysmorphology, which may include hypertelorism, downward slanting eyes, epicanthal folds, and low-set and posteriorly rotated ears. A variety of cardiac defects may be present, including pulmonary stenosis, patent ductus arteriosus, hypertrophic cardiomyopathy, and coarctation of the aorta. Other features include short stature, pterygium colli, short, webbed neck, deafness, motor delay, and bleeding diathesis. Lymphedema may be present prenatally. Noonan syndrome shares some clinical features with cardio-facio-cutaneous (CFC) and Costello syndrome. However, Noonan syndrome patients typically have milder cognitive deficits and fewer ectodermal problems. Patients with RIT1 mutations may also have skin and hair anomalies, such as curly hair, hyperelastic skin, and hyperkeratosis. Prenatal and perinatal abnormalities observed in individuals with RIT1 mutations include polyhydramnios, nuchal translucency, placental abruption, pleural effusion, and chylothorax (Aoki et al., 2013; Gos et al. 2014; Chen et al. 2014; Bertola et al. 2014).
