RGD uses the Human Disease Ontology (DO, https://disease-ontology.org/) for disease curation across species. RGD automatically downloads each new release of the ontology on a monthly basis. Some additional terms which are required for RGD's curation purposes but are not currently covered in the official version of DO have been added. As corresponding terms are added to DO, these custom terms are retired and the DO terms substituted in existing annotations and subsequently used for curation.
An autosomal recessive cerebellar ataxia that is characterized by the onset of ataxia between age three and thirty including axonal sensorimotor neuropathy, cerebellar atrophy and elevated alpha-fetoprotein that has_material_basis_in homozygous or compound heterozygous mutation in the SETX gene on chromosome 9q34.13. Oculomotor apraxia is common, but not universal. (DO)
