This document contains a genetics presentation on osteogenesis imperfecta (OI) types and treatment. It includes several links to external sources of information on OI and the genes involved. It summarizes previous research finding that bone marrow transplant improved growth, bone mineralization, and fracture frequency in children with OI. The presentation notes a current pilot study using bone marrow mesenchymal cell therapy to treat OI after removing cells that could cause rejection, in hopes of increasing growth and bone strength. It contains several citations and links on OI genetics and treatment.
