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.
A retinal disease characterized by foveal hypoplasia with decreased visual acuity and nystagmus that has_material_basis_in homozygous or compound heterozygous mutation in the SLC38A8 gene on chromosome 16q23.3. Optic nerve decussation defects and anterior segment dysgenesis are also frequently seen. (DO)
