The molecular defect in FRDA is the trinucleotide GAA expansion in the first intron of the FXN gene, which encodes frataxin. No studies have yet reported frataxin protein and mRNA levels in a large cohort of FRDA patients, carriers and controls. %U http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0017627
