| Spinocerebellar ataxia type 29 (SCA29) is a rare disease with main features of very slowly progressive or non-progressive ataxia, dysarthria, oculomotor abnormalities and intellectual disability. SCA29 presents at birth, or shortly, after with manifestations of very slowly progressive or non-progressive gait and limb ataxia causing delayed walking and frequent falling in children. Mild developmental delay, learning difficulties, and language dysfunction are frequently reported. Other manifestations include nystagmus, dysarthria, dysmetria, and dysdiadochokinesia. SCA29 is due to mutations in the ITPR1 gene (3p26.1), which is equally the causal gene of SCA15. Inherited autosomal dominantly. |
