Overview
Other Diagnostic Studies
Genetic Analysis
Eight genes all involved in the RAS/MAP kinase pathway have been identified as possible causes for Noonan syndrome. In order of prevalence, the causative mutations involve the following genes: PTPN11, SOS1, KRAS, NRAS, RAF1, BRAF, SHOC2, and CBL. Definitive diagnosis is usually with genetic testing which is commonly by chip-based sequencing, to simultaneously test all the genes that could be involved. [1]
