Frataxin levels in peripheral tissue in Friedreich ataxia [PDF]

Annals of Clinical and Translational Neurology, 2015
Friedreich ataxia (FRDA) is an autosomal recessive ataxia resulting from mutations in the frataxin gene (FXN). Such mutations, usually expanded guanine-adenine-adenine (GAA) repeats, give rise to decreased levels of frataxin protein in both affected and unaffected tissues.

Friedreich's ataxia: the vicious circle hypothesis revisited

BMC Medicine, 2011
Friedreich's ataxia, the most frequent progressive autosomal recessive disorder involving the central and peripheral nervous systems, is mostly associated with unstable expansion of GAA trinucleotide repeats in the first intron of the FXN gene, which ...

Frataxin Is Localized to Both the Chloroplast and Mitochondrion and Is Involved in Chloroplast Fe-S Protein Function in Arabidopsis. [PDF]

PLoS ONE, 2015
Frataxin plays a key role in eukaryotic cellular iron metabolism, particularly in mitochondrial heme and iron-sulfur (Fe-S) cluster biosynthesis. However, its precise role has yet to be elucidated. In this work, we studied the subcellular localization of

Multimodal Imaging Investigation of the Dentato‐Thalamo‐Cortical Pathway in Friedreich's Ataxia

Movement Disorders, Volume 41, Issue 4, Page 909-920, April 2026.
Abstract Background Friedreich's ataxia (FRDA) is a spinocerebellar neurodegenerative disorder. The dentato‐thalamo‐cortical (DTC) pathway, an important cerebellar output involved in motor control, plays a crucial role in the neural mechanisms underlying ataxia symptoms in FRDA.

Biophysical characterisation of the recombinant human frataxin precursor [PDF]

FEBS Open Bio, 2018
Friedreich's ataxia is a disease caused by a decrease in the levels of expression or loss of functionality of the mitochondrial protein frataxin (FXN). The development of an active and stable recombinant variant of FXN is important for protein replacement therapy.

Clinical, Genetic, and Imaging Characteristics of SCA27B: Insights from a Large Dutch Cohort

Movement Disorders, Volume 41, Issue 4, Page 928-936, April 2026.
Abstract Background Deep intronic GAA repeat expansions in intron 1 of the FGF14 gene were identified in 2023 as cause of late‐onset cerebellar ataxia. Since then, GAA‐FGF14‐related ataxia (SCA27B) has emerged as one of the most common genetic causes of late‐onset cerebellar ataxia.

The Cerebellar Cognitive‐Affective Syndrome Scale Reveals Consistent, Early, and Progressive Neuropsychological Deficits in Autosomal‐Recessive Spastic Ataxia of Charlevoix‐Saguenay: A Large International Cross‐Sectional Study

Movement Disorders, Volume 41, Issue 4, Page 1034-1040, April 2026.
Abstract Background Neuropsychological deficits have been observed in patients with cerebellar damage, but never thoroughly investigated in autosomal recessive spastic ataxia of Charlevoix‐Saguenay (ARSACS). Objectives The goal is the characterization of presence, severity, and profile of neuropsychological deficits in ARSACS using the cerebellar ...

The mitochondrial protein frataxin prevents nuclear damage [PDF]

Human Molecular Genetics, 2002
The mitochondrial protein frataxin helps maintain appropriate iron levels in the mitochondria of yeast and humans. A deficiency of this protein in humans causes Friedreich's ataxia, while its complete absence in yeast (Delta yfh1 mutant) results in loss of mitochondrial DNA, apparently due to radicals generated by excess iron. We found that the absence
