Friedreich's ataxia (FRDA) affects very young persons. In a large series, the mean ages of onset and death were 11 and 38 years, respectively. The clinical spectrum of FRDA has expanded after genetic confirmation of the mutation became a routine laboratory test. The main cause of death in juvenile-onset FRDA is cardiomyopathy whereas patients with late-onset are more likely to succumb to neurological disability or an intercurrent illness.
