Friedreich's ataxia (FRDA) is an autosomal recessive neurodegenerative disease affecting 1 in 50,000 people and is caused by a GAA-trinucleotide expansion in the frataxin gene located on chromosome locus 9q13 which results in a markedly reduced expression of frataxin, a small mitochondrial protein. The exact function of frataxin is still unknown and currently there is no approved treatment available. In the near future there will be a high demand for measuring frataxin protein levels due to the development of therapeutic strategies for FRDA based on manipulating frataxin expression levels in vivo.
