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.
Term:
Autosomal Recessive Limb-Girdle Muscular Dystrophy Type 23
A disease characterized by slowly progressive proximal muscle weakness primarily affecting the lower limbs and resulting in gait difficulties. Additional features include white matter abnormalities on brain imaging, increased serum creatine kinase, and dystrophic features.
