FA treatments that target mitochondria may best help patients

Therapies that aid mitochondria, cellular organelles responsible for producing most of the energy needed by cells, may help with physical function and heart health in people with Friedreich’s ataxia (FA), according to a review of published studies. Findings appear to support the benefits of Skyclarys (omaveloxolone), the only…

Voice-based analysis may help differentiate FA from other diseases

Analyzing patients’ voices using machine learning may help to identify Friedreich’s ataxia (FA) and differentiate it from other neurological disorders, a new study shows. “The implications of this approach are substantial and provide new opportunities for healthcare, particularly for remote and rural areas where access to health providers might…

Interferon gamma helps protect cells from damage in disease model

Treatment with interferon gamma (IFN-gamma), an immune signaling molecule, helped to protect against damage in a cellular model of Friedreich’s ataxia (FA), a study reports. Although IFN-gamma failed to show clear benefits in clinical trials, these new findings “could help in the design of better therapeutic schedules and shed…

Gene abnormality in FA muscle cells is a ‘double hit’: Study

Fredrich’s ataxia (FA) impairs the regulation of hundreds of genes in muscle cells, resulting in reduced activity in those responsible for mitochondrial function and increased activity of repressor genes, a study reports. Addressing both aspects of this genetic abnormality “double hit” may be necessary to achieve the best therapeutic…
