RGD uses the Human Disease Ontology (DO, 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.

Definition:Multiple hereditary exostoses (EXT) is an autosomal dominant disorder characterized by multiple projections of bone capped by cartilage, most numerous in the metaphyses of long bones, but also occurring on the diaphyses of long bones. Flat bones, vertebrae, and the ribs may also be affected, but the skull is usually not involved. Deformity of the legs, forearms (resembling Madelung deformity), and hands is frequent. Multiple exostoses type I (EXT1) is caused by heterozygous mutation in the gene encoding exostosin-1 (EXT1) on chromosome 8q24. (OMIM)
Synonyms:exact_synonym: EXT;   EXT1;   hereditary multiple exostoses 1
