Final answer:
Hypertrophic cardiomyopathy is commonly the cause of death in Friedreich ataxia.
Step-by-step explanation:
Friedreich ataxia is commonly associated with hypertrophic cardiomyopathy as the cause of death. Hypertrophic cardiomyopathy is a condition where the heart muscle becomes thickened, making it harder for the heart to pump blood effectively. This can lead to heart failure, which is a common cause of death in individuals with Friedreich ataxia. Other symptoms of Friedreich ataxia include a staggering gait, frequent falling, nystagmus, dysarthria, pes cavus, hammer toes, and diabetes mellitus.
