Clinical Utility

The Noonan Spectrum Disorders, also known as RASopathies, are a group of developmental syndromes characterized by extensive clinical and genetic heterogeneity. They include:


1- Noonan syndrome
2- Cardio-facio-cutaneous syndrome
3- Noonan syndrome with multiple lentigines, previously known as LEOPARD syndrome
4- Costello syndrome


Although there is a considerable phenotypic overlap among the various syndromes, each syndrome is characterized by distinct clinical features.
