Osteogenesis imperfecta (IPA: / ˌ ɒ s t i oʊ ˈ dʒ ɛ n ə s ɪ s ˌ ɪ m p ɜːr ˈ f ɛ k t ə /; [4] OI), colloquially known as brittle bone disease, is a group of genetic disorders that all result in bones that break easily.
Figures in film, television, video games and novels depicted as having osteogenesis imperfecta include: Samuel L. Jackson's character Elijah Price in M. Night Shyamalan's 2000 film Unbreakable and its 2019 follow-up Glass, who was born with type I osteogenesis imperfecta and who adopts his childhood nickname "Mr. Glass" as a villain identity. [62]

Osteogenesis imperfecta, type I: Osteogenesis imperfecta is the most common disorder caused by mutations in this gene. Mutations that inactivate one of the two copies of the COL1A1 gene cause osteogenesis imperfecta type I. The mutated copy of the gene does not produce any pro-alpha1(I) collagen chains.
The genetics of Bruck syndrome differs from osteogenesis imperfecta. Osteogenesis imperfecta usually involves autosomal dominant mutations to COL1A1 or COL1A2 which encode type 1 procollagen. [ 6 ] Bruck syndrome is linked to mutations in two genes, and therefore is divided in two types.
The Brittle Bone Society was established in 1968 in Dundee by Margaret Grant, who has OI. When she was young, Grant was aware that there was virtually no support for people with OI and that many medical professionals knew little or nothing about the condition. When her daughter Yvonne was born some years later, very little had changed.
Sillence created the standard four-type system of osteogenesis imperfecta in 1979. [8] It enabled progress into the molecular causes of the disorder and collagen mutations. In 2012, Sillence delivered the Human Genetics Society of Australasia Oration, a prestigious lecture in his field. [9]
A bone fracture may be the result of high force impact or stress, or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis, osteopenia, bone cancer, or osteogenesis imperfecta, where the fracture is then properly termed a pathologic fracture.
