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 2X
An autosomal recessive muscle disorder characterized by slowly progressive onset of proximal lower limb weakness in adulthood. Affected individuals also develop cardiac arrhythmias resulting in syncopal episodes as young adults or later in life. LGMD2X is caused by homozygous mutation in the BVES gene on chromosome 6q21.
