Adult onset neurodegenerative disorder
Gene: ATCAY
Autosomal recessive Cayman cerebellar ataxia, identified by Johnson et al. (1978) in a population isolate on Grand Cayman Island, is characterized by marked psychomotor retardation and prominent nonprogressive cerebellar dysfunction including nystagmus, intention tremor, dysarthria, and wide-based ataxic gait. Hypotonia is present from early childhood; retinal abnormalities are absent. 2 variants found in the isolated population - non-progressive so red.Created: 2 Sep 2019, 4:06 p.m. | Last Modified: 2 Sep 2019, 4:06 p.m.
