New Findings from Medical University of Innsbruck Describe Advances in Friedreich Ataxia (Skeletal Muscle Involvement in Friedreich Ataxia).

A recent study conducted by the Medical University of Innsbruck in Austria has shed light on the skeletal muscle involvement in Friedreich Ataxia (FRDA), an inherited neuromuscular disorder caused by a deficiency of the mitochondrial protein frataxin. The research found that frataxin deficiency leads to impaired mitochondrial function and adenosine triphosphate production, resulting in progressive balance and coordination disorders. In addition to neurological symptoms, FRDA also affects the striated muscles, particularly the heart, leading to hypertrophic cardiomyopathy and premature mortality. The study emphasizes the importance of investigating skeletal muscle in FRDA for the development of biomarkers and future therapeutic strategies. [Extracted from the article]
