Most cases of apparently idiopathic hypertrophic cardiomyopathy (HCM) in children are caused by mutations in cardiac sarcomere protein genes. HCM also commonly occurs as an associated feature in some patients with disorders caused by mutations in genes encoding components of the RAS-mitogen activated protein kinase (MAPK) signaling pathway. Although diagnosis of these disorders is based on typical phenotypic features, the dysmorphic manifestations can be subtle and therefore overlooked. The aim of this study was to determine the prevalence of mutations in RAS-MAPK genes in preadolescent children with idiopathic HCM.
