osteogenesis imperfecta
Let an agent explain osteogenesis imperfecta and its types in general terms, relay diagnosis, management and support information from clinical and patient organisation sources, distinguish it from other bone fragility conditions and from non-accidental injury, and route personal questions to clinicians and genetic counsellors.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain osteogenesis imperfecta and its types in general terms, relay diagnosis, management and support information from clinical and patient organisation sources, distinguish it from other bone fragility conditions and from non-accidental injury, and route personal questions to clinicians and genetic counsellors.
A group of inherited disorders of connective tissue, mostly caused by variants in the type I collagen genes COL1A1 and COL1A2 or in genes affecting collagen processing, that make bones fragile and prone to fracture; osteogenesis imperfecta ranges from mild forms with few fractures to severe and lethal forms, may involve blue sclerae, hearing loss, dental defects and short stature, and is managed by multidisciplinary care including bisphosphonates, surgery and physiotherapy.
What it is for: Not applicable; a genetic disorder.
It can be explain the condition and its types; relay diagnosis and management principles; relay support and patient organisation information; route personal questions to clinicians.
Distinguishing features
Collagen-related bone fragility
Wide severity range
Genetic classification
Multidisciplinary care
What it looks like
Not a visible object; signs may include frequent fractures, bone deformity, blue sclerae and short stature.
Physical character
prevalence: about 1 in 15000-20000 births - per epidemiological sources
types: over 20 count - by genetic classification
How it is recognised
Inherited bone fragility from collagen defects
Numbered types by severity and genetics
Osteoporosis and non-accidental injury are different causes of fractures

- How should guidelines and registries be linked?
- The registry entry has merged aliases naming numbered types; should they be split off?
