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 syndrome characterized by limb defects, usually bilateral, like cleft hands or feet and longitudinal defects involving radius or ulna, tibia or fibula and renal anomalies which include agenesis, hypoplasia and rarely polycystic kidneys. Additional malformations may involve the oro-mandibular region, the trachea and lungs, skin derivatives including sweat glands, mammary glands, the uterus, vas deferens, the nasal placodes and the eyes.
