KEGG   DISEASE: Noonan syndrome and related disordersHelp
H00523                      Disease                                

Noonan syndrome and related disorders, including:
Noonan syndrome (NS);
Leopard syndrome (LS);
Noonan syndrome-like with loose anagen hair (NS/LAH);
CBL-mutation associated syndrome (CBL);
Neurofibromatosis type 1 (NF1);
Neurofibromatosis-Noonan syndrome (NFNS);
Legius syndrome;
Cardiofaciocutaneous syndrome (CFCS);
Costello syndrome (CS);
Watson syndrome
Noonan syndrome comprises genetically heterogeneous disorders that usually include postnatally reduced growth, distinctive facial dysmorphic features, and congenital heart defects and related disorders show considerable overlapping phenotypes with Noonan syndrome. These disorders are caused by germline mutations in genes that encode components or regulators of the Ras/MAPK pathway, and are called RASopathies.
