Variant Names: 
Osteogenesis imperfecta with unusual skeletal lesions

Gnathodiaphyseal dysplasia (GDD; MIM 166260) is an autosomal dominant generalized skeletal syndrome. It is also known as osteogenesis imperfecta with unusual skeletal lesions. GDD is characterized by cementoosseous lesions of the jawbones that can cause facial deformity, jaw infections, osteopenia, bone fractures, bowing/cortical thickening of tubular bones, and diaphyseal sclerosis of long more
