RGD uses the Human Disease Ontology (DO, 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.

Definition:Familial retinal arterial tortuosity is characterized by marked tortuosity of second- and third-order retinal arteries with normal first-order arteries and venous system. Two-thirds of patients experience variable degrees of symptomatic transient vision loss due to retinal hemorrhage following minor stress or trauma. (OMIM)
Synonyms:exact_synonym: RATOR;   RETINAL HEMORRHAGE WITH VASCULAR TORTUOSITY;   retinal arteriolar tortuosity;   tortuosity of retinal arteries
