Noonan Syndrome and Related Disorders: A Review of Clinical Features and Mutations in Genes of the RAS/MAPK Pathway

Abstract excerpt

Noonan syndrome (NS) is one of the most common syndromes transmitted by a mendelian mode. In recent years, germline mutations that affect components of the RAS-MAPK (mitogen-activated protein kinase) pathway were shown to be involved in the pathogenesis of NS and four rare syndromes with clinical features overlapping with NS: Leopard syndrome, cardio-facio-cutaneous syndrome, Costello syndrome and...
