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:
Carpal Synostosis with Dysplastic Elbow Joints and Brachydactyly
Liebenberg syndrome is an upper limb malformation characterized by the combination of dysplastic elbow joints and the fusion of wrist bones with consequent radial deviation. LBNBG, or carpal synostosis with dysplastic elbow joints and brachydactyly, is caused by genomic rearrangement resulting in misexpression of the PITX1 gene on chromosome 5q31. (OMIM)
