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 disease characterized by atrial arrhythmias, including flutter and fibrillation, atrial structural abnormalities with hypertrophic cardiomyopathy and fibrosis, and hypertension. Caused by homozygous mutation in the CORIN gene on chromosome 4p12.
