Osteogenesis Imperfecta (OI), also known as Brittle Bones, is a genetic condition caused by a mutation in one of the genes responsible for the production of type one collagen, a major protein in bone. This leads to weak bones which fracture easily.
According to the Brittle Bone Society, OI affects around 1 in every 15,000 people, meaning around 5000 people in the UK are currently living with the condition.
Those with OI have a 50% chance of passing it on to their children, although 25% of children born with the condition have no family history of it.
