Involvement in diseasei

Spinocerebellar ataxia 8 (SCA8) [MIM:608768]: Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA8 is an autosomal dominant cerebellar ataxia (ADCA). It is caused by expansion of a CAG repeat in ATXN8, which is translated into a nearly pure polyglutamine protein which forms 1C2-positive inclusions in Purkinje cells and other neurons.1 Publication
Note: The disease is caused by mutations affecting the gene represented in this entry.

Polymorphismi

The length of the poly-Gln expansion is variable and may contain one or more interruptions that introduce arginines into the polyglutamine repeat tract.
