Osteogenesis imperfecta (OI), or brittle bone disease, is a heritable disorder of connective tissue characterized by bone fragility and low bone mass. OI is clinically and genetically heterogeneous with severity varying from mild to perinatal lethal. Mutations in the COL1A1 and COL1A2 genes cause approximately 90% of OI cases. COL1A1 and COL1A2 encode the alpha 1 and alpha 2 procollagen chains of type I collagen.read more
