Abstract

RASopathies – caused by mutations in the RAS/MAPK signaling pathway – are frequently associated with cardiac diseases, such as hypertrophic obstructive cardiomyopathy. Although cibenzoline is useful for adult hypertrophic obstructive cardiomyopathy patients, little is known about its effect in children. Here, we report two paediatric cases of hypertrophic obstructive cardiomyopathy associated with RASopathies where the condition was improved by cibenzoline.
