Dominant Multiple Epiphyseal Dysplasia (DMO) is a rare genetic disorder that affects the growth of bones in the body. It is caused by a mutation in the COMP gene, which is responsible for the production of cartilage. Symptoms of DMO include short stature, joint pain, and deformities of the hips, knees, and ankles. People with DMO may also experience hearing loss, vision problems, and learning disabilities. Treatment for DMO is focused on managing the symptoms and preventing further joint damage.
