Heredoataxia Cerebellar

Heredoatasia of the cerebellar system is a group of inherited degenerative diseases in which the cerebellum is damaged. Heredoataxic disorders are divided into **familial Friedreich's ataxia and other** forms. Familial GM accounts for 95% of cases of Friedreim's ataxia. The cause is a mutation in the FXN gene, located on the long arm of chromosome 9. The mutation provides a partial defect in the transport protein from excess glycophosphatidylinositol, manifested by a progressive decrease in the content of this protein in the body, leading to cellular energy deficiency and mitochondrial inhibition
