Boosting the breakdown of fat promoted higher levels of frataxin, the deficiency of which is a hallmark of Friedreich’s ataxia, and reduced the risk of diabetes in a mouse model of the disease. The study, “Interplay of…

Increasing the levels of a protein known as TSPO in glial cells — which provide nutrients to nerve cells and help with their communication — extended survival and improved mobility in a fruit fly model of Friedreich’s ataxia (FA). These preclinical findings suggest that “TSPO might be a relevant therapeutic target for this…

Levels of iron in the blood, along with iron stored in the liver and spleen, are significantly lower in adults with Friedreich’s ataxia (FA) relative to healthy adults, and the more severe the FA-causing mutation, the lower the iron in blood and organs, a study shows. The findings highlight…

Thickening of the heart muscle, although rare, may be the first manifestation of Friedreich’s ataxia (FA) in children, according to a new study. These findings suggest genetic testing to confirm the FA diagnosis should be considered in children with unexplained hypertrophic cardiomyopathy, when the walls of the left…

Stealth Biotherapeutics’ investigational therapy SBT-589 showed protective effects against cell energy deficits and heart muscle disease across several preclinical models of Friedreich’s ataxia (FA), including a mouse model of pronounced heart disease, according to new laboratory data. SBT-589 is designed to boost the activity of mitochondria — known…

Levels of the frataxin protein in the blood correlate with disease progression and disability status in Friedreich’s ataxia (FA) patients, a study reports.

The study “Ocular Involvement in Friedreich Ataxia Patients and…

The number of treatments for children with rare diseases has grown over the past decade, according to a new study. However, despite the increase, nearly 7,000 rare diseases are still lacking treatment. And federal incentives to boost treatment development for these rare diseases have primarily focused not on creating new…

Exenatide, a drug that mimics the effects of the gut hormone GLP-1, increased the levels of frataxin — a protein involved in iron metabolism, whose deficiency leads to Friedreich’s ataxia (FA) — in a mouse model of the disease, a new study shows. Treatment with exanatide also improved the…

Friedreich’s ataxia can occur as a late-onset disease, with symptoms appearing after age 50, a case-report shows. Late-onset cases lack the typical symptoms and disease progresses slowly, highlighting the need for genetic testing in cases of older patients showing difficulty coordinating movements or other atypical presentations to confirm the diagnosis. The…

A group of researchers compiled a database of small RNAs that circulate in the blood of Friedreich’s ataxia (FA) patients with different disease symptoms. Researchers hope this resource will assist research into FA’s mechanisms and possibly identify biomarkers of disease progression and patients’ response to treatment. The study,…

As therapies for Friedreich’s ataxia seek to increase the amount of frataxin, whose shortage underlies the disease, scientists conducting an in vitro study warn that levels of the protein must be tightly regulated because overproduction may result in detrimental effects. The study, “Adding a temporal dimension to the…

Compounds similar to the chemical methylene blue, which has been shown to have therapeutic benefits in several diseases, were seen to increase frataxin levels and the production of mitochondria in Friedreich’s ataxia (FA) cells. The study, “Lipophilic methylene blue analogues enhance mitochondrial function and increase frataxin levels in a…
