U of MN researchers identify ataxia gene

... 2006. Ataxia is a hereditary disease that causes loss of coordination resulting in difficulty with everyday tasks such as walking, speech, and writing. About 1 in 17,000 people have a genetic form of ataxia. Spinocerebellar ataxia type 5 (SCA5) is a dominant gene disorder; if a parent has the disease,...
