To read the full abstract: J Bone Miner Res 2018;33(7):1260-1271Osteogenesis imperfecta (OI) is characterized by early-onset skeletal fragility, often short stature, blue sclerae and some other features. OI is caused by mutations in the two genes encoding type I collagen, namely COL1A1 and COL1A2. Some previous reports have indicated that when the mutation involves the C-propeptide cleavage site in e...
