Friedreich ataxia (FRDA) is the most common cause of childhood onset ataxia. We report on a 4 year old boy who suffered sudden cardiac death and was found to have a dilated cardiomyopathy with left ventricular hypertrophy on post-mortem studies. Molecular genetic testing subsequently confirmed the diagnosis of Friedreich ataxia. To our knowledge, this is the first report of Friedreich ataxia presenting as sudden cardiac death in early childhood.
