Frequency of ZFHX3‐Mediated Spinocerebellar Ataxia 4 in a US Undiagnosed Ataxia Cohort

open access: yesMovement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia 4 (SCA4) is a late‐onset dominant ataxia with neuropathy caused by exonic GGC repeat expansion in the ZFHX3 gene thought to originate from a Swedish founder event. The GC‐rich expansion is highly thermodynamically stable, posing challenges for standard clinical genetic testing methods.

Inducible and reversible phenotypes in a novel mouse model of Friedreich’s Ataxia

open access: yeseLife, 2017
Friedreich's ataxia (FRDA), the most common inherited ataxia, is caused by recessive mutations that reduce the levels of frataxin (FXN), a mitochondrial iron binding protein.

Technologies for engineering repetitive DNA

open access: yesQuantitative Biology, Volume 14, Issue 3, September 2026.
Abstract Repetitive DNA, a fundamental architectural element of genomes, is widespread across organisms and comprises about 54% of the human genome. With advances in long‐read sequencing and bioinformatics approaches, highly repetitive sequences can now be characterized in depth.

Friedreich's ataxia: clinical aspects and pathogenesis.

open access: yes, 1999
Friedreich's ataxia is the most frequent inherited ataxia in Caucasians. It is caused by deficiency of frataxin, a highly conserved nuclear-encoded protein localized in mitochondria.

Friedreich's ataxia protein: Phylogenetic evidence for mitochondrial dysfunction

open access: yes, 1996
Friedreich's ataxia is the most common inherited spinocerebellar ataxia. A decade of linkage and physical mapping studies have culminated in the identification of the Friedreich's ataxia gene.

Chemical synthesis of lipophilic methylene blue analogues which increase mitochondrial biogenesis and frataxin levels

open access: yesData in Brief, 2018
As part of an ongoing program to develop potential therapeutic agents for the treatment of the neurodegenerative disease Friedreich׳s ataxia (FRDA), we have prepared a number of lipophilic methylene blue analogues.

Systematic Review: Quantitative Susceptibility Mapping (QSM) of Brain Iron Profile in Neurodegenerative Diseases

open access: yesFrontiers in Neuroscience, 2021
Iron has been increasingly implicated in the pathology of neurodegenerative diseases. In the past decade, development of the new magnetic resonance imaging technique, quantitative susceptibility mapping (QSM), has enabled for the more comprehensive ...

Pharmacological Activation of NRF2 by Omaveloxolone Upregulates NRF2‐Target Proteins in SMA Type I Human Fibroblasts

open access: yesThe FASEB Journal, Volume 40, Issue 12, 30 June 2026.
SMA type I patient‐derived fibroblasts exhibit reduced basal NRF2 pathway output, reflected by decreased NQO1, xCT, and PGC1α. Pharmacological NRF2 activation with omaveloxolone (OMAV) increases cell viability and induces NRF2 target proteins in both control and SMA fibroblasts.

Accuracy of clinical diagnostic criteria for Friedreich's ataxia

open access: yes, 2000
The accuracy of the diagnostic criteria for Friedreich's ataxia proposed by Harding and by the Quebec Cooperative Study on Friedreich's Ataxia was studied in 142 patients with progressive unremitting ataxia of autosomal recessive inheritance or sporadic ...

Analysis of Postural Control in Sitting by Pressure Mapping in Patients with Multiple Sclerosis, Spinal Cord Injury and Friedreich’s Ataxia: A Case Series Study

open access: yesSensors, 2020
The postural control assessments in patients with neurological diseases lack reliability and sensitivity to small changes in patient functionality. The appearance of pressure mapping has allowed quantitative evaluation of postural control in sitting ...
