The rate of progression varies from person to person. Generally, within 10 to 20 years after the first symptoms appear, people with Friedreich ataxia need to consistently use a wheelchair. Life expectancy may be affected, and many people with Friedreich ataxia die in adulthood from the associated heart disease. However, some people with less severe symptoms of Friedreich ataxia live much longer, sometimes into their sixties or seventies[2].
This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
