Osteogenesis Imperfecta (OI) is a rare hereditary disorder that leads to fragile bone mineralization and is most often due to a genetic defect in type I collagen, the primary collagen subtype that comprises bone.

It has been recognized in countries throughout the world and has a variable age and severity of presentation depending on the subtype of OI.
