Friedreich-Ataxie – eine Multisystemerkrankung
摘要
Friedreich’s ataxia is the most common hereditary ataxia globally, most often caused by a homozygous GAA repeat expansion in the FXN gene, leading to a deficiency in the mitochondrial protein frataxin. It primarily affects the peripheral nerves, dorsal columns of the spinal cord and cerebellum, as well as the heart, skeleton, and pancreas. Friedreich’s ataxia typically presents in adolescents with progressive ataxia, although onset can be variable, ranging from early childhood to late adulthood. In addition, a multitude of extraneural features are frequently present, including cardiomyopathy, scoliosis, and diabetes. Mean life expectancy is 35–40 years. Treatment is largely supportive, comprising physiotherapy, occupational therapy, speech and language therapy, and rehabilitation. Recently, omaveloxolone, the first medication for Friedreich’s ataxia, was approved by the European Commission.
