Eye movement abnormalities may help detect, track FA progression

People with Friedreich’s ataxia often show abnormalities in their eye movements and looking for characteristic changes there may help diagnose the disease and track its progression, a review study finds. “Quantitative oculomotor [eye movement] testing in [Friedreich’s ataxia] may facilitate early diagnosis and provide value in monitoring disease…

Potential therapy ATH434 may target toxic iron buildup in cells

An experimental compound called ATH434, currently being evaluated in clinical trials for a neurological disorder called multiple system atrophy, also may have the potential to treat Friedreich’s ataxia (FA). Data specifically indicate that ATH434 could help to reduce the toxic buildup of iron in cells that is characteristic…

FA likely marked by problems making mitochondrial proteins

A deficiency of frataxin, the protein whose lack causes Friedreich’s ataxia, leads to problems with mitochondrial translation — the molecular process by which new proteins are made in the mitochondria, the so-called powerhouse of the cell responsible for energy production — according to a new study. The findings specifically…

FA community voices eagerness, expectations for gene therapy

People in the Friedreich’s ataxia (FA) community await the possibility of gene therapies for their disease, with many saying they would participate in gene therapy trials regardless of the potential for side effects or other consequences. Around half of the survey’s 137 respondents expected that such treatment — delivering…
