OI, Type I: A genetic condition characterized mainly by fragile bones that fracture easily and blue sclerae. The fractures tend start during early childhood (when walking starts) and becomes worse after menopause or in old age. Fractures tend to heal normally. Type I is the mildest form of osteogenesis imperfecta and results from a reduced amount of normal collagen in the body. Other forms of osteogenesis imperfect tend to involve the presence of abnormal collagen. More detailed information about the symptoms, causes, and treatments of OI, Type I is available below.
