Interferon-gamma (IFN-γ) has been shown to induce frataxin production in many cell types. In this study, the clinical features, tolerability, and the prognosis of individuals with FRDA to whom IFN-γ was administered in a university hospital were evaluated retrospectively and the results were discussed. To the best of our knowledge, this is the first study conducted in our country to evaluate the effect of IFN gamma on this patient group.
