Friedreich ataxia is a rare, inherited disease. It causes a gradual breakdown of the nervous system. Friedreich ataxia affects nerves in the brain and spinal cord that control movement. It also affects sensory nerves that help with coordination. In later stages, the disease can cause injury to the heart and pancreas.
Friedreich ataxia is caused by a problem with a gene called the frataxin gene. This gene is found on chromosome 9q13. To develop this disease, a person must inherit a copy of the defective gene from each parent. However, there are some people with Friedreich ataxia that have no family history of the disorder.
You will be asked about your symptoms. You will also be asked about your medical history, family history, and current medication. A physical exam will be done. If Friedreich ataxia is suspected, you may also see a doctor who specializes in the nervous system.
