Ataksian
Ataksian is a rare genetic disorder characterized by the progressive degeneration of the nervous system, leading to severe intellectual disability, motor impairment, and other neurological symptoms. The term "ataksian" is derived from the Greek word "ataksia," meaning lack of coordination, reflecting the primary symptom of the disorder. The condition is caused by mutations in specific genes, with the most common being ATXN1, ATXN2, and ATXN3, which are responsible for encoding proteins involved in the maintenance of neuronal structure and function.
Ataksian can be classified into several subtypes based on the affected gene and the resulting clinical presentation.
The diagnosis of ataksian typically involves a combination of clinical evaluation, genetic testing, and neuroimaging studies.
