With an incidence of 1 in 50,000172,173, and a carrier prevalence of 1 in 100174, Friedreich’s ataxia (FRDA) is by far the most prevalent disease linked to defective Fe-S cluster formation.
FRDA is an autosomal recessive genetic disease caused by a GAA-trinucleotide repeat expansion in an intron of the frataxin gene, a protein involved in the ISC pathway.
