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.

Familial Horizontal Gaze Palsy with Progressive Scoliosis, 1
HGPPS is an autosomal recessive neurologic disorder characterized by eye movement abnormalities apparent from birth and childhood-onset progressive scoliosis. These features are associated with a developmental malformation of the brainstem including hypoplasia of the pons and cerebellar peduncles and defective decussation of certain neuronal systems. Cognitive function is normal. Familial horizontal gaze palsy with progressive scoliosis-1 (HGPPS1) is caused by homozygous or compound heterozygous mutation in the ROBO3 gene on chromosome 11q24.
