Clinical and molecular spectra of BRAF-associated RASopathy

Noonan syndrome (NS) and cardio-facio-cutaneous (CFC) syndrome are the most common subtypes of RASopathy. As an effector of Ras, BRAF is one of the molecules responsible for RASopathy. We investigated the phenotypic and genotypic features of 26 patients with BRAF-associated RASopathy. The clinical diagnoses were CFC (n = 21, 80.8%), NS (n = 3, 11.5%), NS/CFC (n = 1, 3.8%), and undefined syndromic intellectual disability (ID) (n = 1, 3.8%). The...
