Friedreich’s ataxia (FRDA) is a form of neuropathy that was fi rst described by Nikolaus Friedreich in a series of 5 papers published from 1863-1877 (1). Freidreich was a third generation physician from Heidelberg, Germany. His grandfather was the fi rst to describe idiopathic facial paralysis, also known as Bell’s palsy. Friedreich trained to be a pathologist under Rudolf Virchow, who proposed...
BACKGROUND Friedreich ataxia is an autosomal recessive disease with no available therapy. Clinical trials with erythropoietin in Friedreich ataxia patients have yielded conflicting results, and the long-term effect of the drug remains unknown. METHODS We designed a double-blind, placebo-controlled, multicenter trial to test the efficacy of epoetin alfa on 56 patients with Friedreich ataxia. T...
Friedreich ataxia is a progressive neurodegenerative disorder caused by loss of function mutations in the frataxin gene. In order to unravel frataxin function we developed monoclonal antibodies raised against different regions of the protein. These antibodies detect a processed 18 kDa protein in various human and mouse tissues and cell lines that is severely reduced in Friedreich ataxia patient...
BACKGROUND Friedreich ataxia is an autosomal recessive neurodegenerative disease caused by reduced expression levels of the frataxin gene (FXN) due to expansion of triplet nucleotide GAA repeats in the first intron of FXN. Augmentation of frataxin expression levels in affected Friedreich ataxia patient tissues might substantially slow disease progression. METHODOLOGY/PRINCIPAL FINDINGS We uti...
OBJECTIVE To assess the efficacy of idebenone on neurological function in patients with Friedreich ataxia. DESIGN Randomized, double-blind, placebo-controlled intervention trial. SETTING Children's Hospital of Philadelphia and the University of California at Los Angeles. PARTICIPANTS Seventy ambulatory pediatric patients (age, 8-18 years) with a baseline International Cooperative Ataxia R...
background: friedreich ataxia (frda) is an autosomal recessive disorder caused by guanine-adenine-adenine (gaa) triplet expansions in the fxn gene. its product, frataxin, which severely reduces in frda patients, leads to oxidative damage in mitochondria. the purpose of this study was to evaluate the triple nucleotide repeated expansions in iranian frda patients and to elucidate distinguishable ...
BACKGROUND Friedreich ataxia, an autosomal recessive neurodegenerative and cardiac disease, is caused by abnormally low levels of frataxin, an essential mitochondrial protein. All Friedreich ataxia patients carry a GAATTC repeat expansion in the first intron of the frataxin gene, either in the homozygous state or in compound heterozygosity with other loss-of-function mutations. The GAA expansio...
Friedreich ataxia, the most common type of inherited ataxia, is itself caused in most cases by a large expansion of an intronic GAA repeat, resulting in decreased expression of the target frataxin gene. The autosomal recessive inheritance of the disease gives this triplet repeat mutation some unique features of natural history and evolution. Frataxin is a mitochondrial protein that has homologu...
