In Friedreich's ataxia, caused by mutation of the gene encoding the mitochondrial protein frataxin, the major cause of mortality is heart failure. Using mice lacking frataxin in the heart, Hélène Puccio and her colleagues demonstrate that frataxin gene therapy can correct mitochondrial metabolism and reverse heart damage, raising the possibility of a gene therapy treatment for this disease.
