Overexpression of human and fly frataxins in Drosophila provokes deleterious effects at biochemical, physiological & developmental levels

Friedreich's ataxia (FA), the most frequent form of inherited ataxias in the Caucasian population, is caused by a reduced expression of frataxin, a highly conserved protein. Model organisms have contributed greatly in the efforts to decipher the function of frataxin; however, the precise function of this protein remains elusive.

Long Range Regulation of Human FXN Gene Expression

Friedreich ataxia (FRDA) is the most common form of hereditary ataxia characterized by the presence of a GAA trinucleotide repeat expansion within the first intron of the FXN gene. The expansion inhibits FXN gene expression resulting in an insufficiency of frataxin protein.

Correlation of frataxin content in blood and skeletal muscle endorses frataxin as a biomarker in Friedreich ataxia

Friedreich ataxia is an autosomal recessive disorder caused by mutations in the frataxin gene, leading to reduced levels of the mitochondrial protein frataxin. Assays to quantitatively measure frataxin in peripheral blood have been established. To determine the validity of frataxin as a biomarker for clinical trials, we assessed frataxin in clinically affected tissue.

Neurodegeneration in friedreich's ataxia is associated with a mixed activation pattern of the brain. A fMRI study

Friedreich's ataxia (FRDA) is associated with a distributed pattern of neurodegeneration in the spinal cord and the brain secondary to selective neuronal loss. We used functional MR Imaging (fMRI) to explore brain activation in FRDA patients during two motor-sensory tasks of different complexity, i.e. continuous hand tapping and writing of "8" figure, with the right dominant hand and without visual feedback.
