Friedreich ataxia: an overview [PDF]

Journal of Medical Genetics, 2000
Friedreich ataxia, an autosomal recessive neurodegenerative disease, is the most common of the inherited ataxias. The recent discovery of the gene that is mutated in this condition,FRDA, has led to rapid advances in the understanding of the pathogenesis of Friedreich ataxia. About 98% of mutant alleles have an expansion of a GAA trinucleotide repeat in

Friedreich's Ataxia in the Elderly

Journal of International Medical Research, 1995
Friedreich's ataxia is one of the best defined and most common forms of hereditary ataxia of unknown aetiology. It is transmitted in an autosomal recessive manner, appearing sporadically, usually in childhood or adolescence. The case of an elderly patient with a possible diagnosis of late-onset Friedreich's ataxia is reported; this is thought to be the

FXN Promoter Silencing in the Humanized Mouse Model of Friedreich Ataxia.

PLoS ONE, 2015
BackgroundFriedreich ataxia is caused by an expanded GAA triplet-repeat sequence in intron 1 of the FXN gene that results in epigenetic silencing of the FXN promoter. This silencing mechanism is seen in patient-derived lymphoblastoid cells but it remains

Large Interruptions of GAA Repeat Expansion Mutations in Friedreich Ataxia Are Very Rare

Frontiers in Cellular Neuroscience, 2018
Friedreich ataxia is a multi-system autosomal recessive inherited disorder primarily caused by homozygous GAA repeat expansion mutations within intron 1 of the frataxin gene. The resulting deficiency of frataxin protein leads to progressive mitochondrial

Vitamin E Level In Friedreich’s Ataxic Phenotype Patients In Four Major Hospitals In Baghdad

مجله كليه طب الكندي, 2019
Background: Friedreich ataxia (FRDA) is the most common form of inherited ataxia, comprising one-half of all hereditary ataxias with a carrier rate between 1 in 60 to 1 in 90 and with a disease prevalence of 1 per 29,000.

Expression of human frataxin is regulated by transcription factors SRF and TFAP2.

PLoS ONE, 2010
BackgroundFriedreich 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.

More Than Ataxia: Hyperkinetic Movement Disorders in Childhood Autosomal Recessive Ataxia Syndromes

Tremor and Other Hyperkinetic Movements, 2016
Background: The autosomal recessive ataxias are a heterogeneous group of disorders that are characterized by complex neurological features in addition to progressive ataxia.

Impaired nuclear Nrf2 translocation undermines the oxidative stress response in Friedreich ataxia. [PDF]

PLoS ONE, 2009
BACKGROUND: Friedreich ataxia originates from a decrease in mitochondrial frataxin, which causes the death of a subset of neurons. The biochemical hallmarks of the disease include low activity of the iron sulfur cluster-containing proteins (ISP) and ...

Ataxia with Vitamin E Deficiency

Pediatric Neurology Briefs, 1997
Vitamin E adminstration (100 U/kg daily) resulted in improvements in ataxia, motor strength, and mobility in 2 siblings of a consanguineous Bedouin family with Friedreich ataxia and low serum vitamin E levels treated at Soroka Medical Center, Beer Sheva,

Harmonizing results of ataxia rating scales: mFARS, SARA, and ICARS

Annals of Clinical and Translational Neurology, 2022
The ever‐increasing body of ataxia research provides opportunities for large‐scale meta‐analyses, systematic reviews, and data aggregation. Because multiple standardized scales are used to quantify ataxia severity, harmonization of these measures is ...
