Multiple Exostoses Type I  
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)
