Friedreich ataxia (FRDA), the most common recessive ataxia, is characterized by degeneration of the large sensory neurons and spinocerebellar tracts and cardiomyopathy. It is caused by severely reduced levels of frataxin, a mitochondrial protein involved in iron-sulfur cluster (ISC) biosynthesis. Mouse models have been important tools in dissecting the steps of pathogenesis in FRDA. Furthermore, animal models that reproduce some of the key events in a pathology are essential for the development of effective therapies, both pharmacological and gene therapy approaches. This chapter presents an overview of the current mouse models that have been developed for FRDA.
