Osteogenesis imperfecta type 5
Osteogenesis imperfecta type V is a moderate type of osteogenesis imperfecta (OI; see this term), a genetic disorder characterized by increased bone fragility, low bone mass and susceptibility to bone fractures with variable severity. OI type V is characterized by mild to moderate short stature, dislocation of the radial head, mineralized interosseous membranes, hyperplasic callus, white sclera and no dentinogenesis imperfecta (DI; see this term).
To date 47 cases have been reported.
The causal gene for OI type V is not known
A clinically similar but histologically different type of OI type V (sometimes described as OI type VI) has been described and is thought to be autosomal recessive but the causal gene is not known.
Transmission is thought to be autosomal dominant.
