DNA REPAIR PATHWAYS ARE ALTERED IN NEURAL CELL MODELS OF FRATAXIN DEFICIENCY

 These results suggest that the deficiency of FXN leads to a down-regulation of DNA repair pathways that synergizes with oxidative stress to provoke DNA damage, which may be involved in the pathogenesis of FRDA. Thus, a failure in DNA repair may be considered a shared common molecular mechanism contributing to neurodegeneration in a number of hereditary ataxias including FRDA.
