Summary: To examine range of tissue frataxin (FXN) concentrations, specific ribonucleic acids, other proteins and specialized lipids in the buccal cells, blood, and skin cells of normal healthy volunteers without Friedreich's ataxia (FRDA).

Summary: Spinocerebellar ataxia type 3 (SCA3) is one of autosomal dominant hereditary ataxias. Standing imbalance, unsteady gait, dysmetria, fatigue, and depression would occur gradually. There are no effective treatment or palliative methods for patients in the present days. However, low-dose growth hormone, or its downstream product, insulin-like growth factor I (IGF-1), may deter the progress of SCA3 in...

Summary: The hereditary ataxias are a group of genetic disorders characterized by slowly progressive incoordination of gait and balance impairments in sitting and standing. Trunk local stability during gait is lower in patients with degenerative ataxia than that in healthy adult population.~Given the fact that drug interventions are rare in degenerative diseases and limited to only specific type of disease...

Summary: The primary objective is to test the safety and tolerability of short-term therapy with a nicotinamide adenine dinucleotide (NAD+) precursor (MIB-626) in adults with Friedreich's Ataxia (FA) without overt heart failure and with a left ventricular ejection fraction ≥ 40%. A key secondary objective is to test the effects of MIB-626 on cardiac and skeletal muscle bioenergetics.

Summary: Friedreich's ataxia is a debilitating, inherited disease cause by mutations in a protein called frataxin (FXN). FXN is one of several proteins that controls the production of iron-sulfur clusters, molecules that are essential for energy production in our cells as well as repair of our genetic code embedded in DNA molecules. Friedreich's ataxia (FRDA) and deficiency of FXN results in a nerve diseas...

Summary: This is a natural history study prospectively investigating neuroimaging markers of disease progression in children and adults with Friedreich ataxia (FA). There will be three assessment periods (baseline, 12 and 24 months). The study will include approximately 200 individuals with FA and 100 matched controls recruited across the six international academic sites. Other assessments will include sec...

Summary: To assess the impact of a 12-week virtual seated physical intervention on cardiovascular health and wellness in people with chronic neurological impairments (CNI).

Summary: A drug repositioning effort provided evidence supporting the possible use of Etravirine, a drug approved for the treatment of HIV infections in patients starting from 2 years of age, as a treatment for FA. We found that Etravirine is able to increase Frataxin protein both in vitro - in cells derived from FA patients - and in vivo - in the heart and skeletal muscle of Frataxin-deficient YG8 mice. B...

Summary: Spinocerebellar ataxia type 10 (SCA10) is a hereditary ataxia whose ancestral mutation occurred in East Asia. The mutation is likely to have migrated during peopling of American continents from East Asia. We found a specific rare DNA variation associated with SCA10. We test whether this variation played a key role in the birth and subsequent spreading of SCA10 mutation.

Summary: Randomized, placebo-controlled trial with a 2x2 factorial design testing the effects of an NAD+ precursor (NR) and exercise on VO2max and Si in Friedreich's Ataxia (FA).~The primary objective of this research is to measure the effect of combination administration (NR + exercise) on aerobic capacity (VO2max) in FA. A key secondary objective is to measure the effect of combination administration (NR...

Summary: The aim of this study is to determine the clinical spectrum and natural progression of Spastic Ataxias (SPAX) and related disorders in a prospective multicenter natural history study, identify digital, imaging and molecular biomarkers that can assist in diagnosis and therapy development and study the genetic etiology and molecular mechanisms of these diseases.

Summary: International, multicenter, observational, longitudinal monitoring study to identify biomarker/s for Friedreich's Ataxia and to explore the clinical robustness, specificity, and long-term variability of these biomarker/s
