osteogenesis imperfecta, which refers to a group of conditions that affect the bones. OI type IV is the most variable form of the condition with symptoms ranging from moderately severe to so mild that it may be difficult to make the diagnosis. Although signs and symptoms can vary, affected people may experience easily broken bones, mild short stature, dentinogenesis imperfecta, adult-onset hearing loss, and normal-to-grey sclerae (the whites of the eye). OI type IV is caused by changes (mutations) in the COL1A1 or COL1A2 gene and is inherited in an autosomal dominant manner. There is currently no cure for OI type IV. Treatment is supportive and based on the signs and symptoms present in each person.Osteogenesis imperfecta type IV (OI type IV) is a type of
