What disease does Mr Glass have?

Where is osteogenesis imperfecta most common?

Four main types of OI have been identified. OI type I is the most common and the mildest form of the disorder. OI type II is the most severe. In most cases, the various forms of osteogenesis imperfecta are inherited as autosomal dominant traits.

What is osteogenesis imperfecta Type 2?

Osteogenesis imperfecta type II is a lethal type of osteogenesis imperfecta (OI; see this term), a genetic disorder characterized by increased bone fragility, low bone mass and susceptibility to bone fractures.

Who is most affected by osteogenesis imperfecta?

OI occurs in approximately 1 in 20,000 individuals, including people diagnosed after birth. OI occurs with equal frequency among males and females and among racial and ethnic groups. Life expectancy varies depending on how severe the OI is, ranging from very brief (lethal form, OI type II) to average.

What causes osteogenesis imperfecta?

Osteogenesis imperfecta type I is caused by mutations in the COL1A1 gene or, less commonly, the COL1A2 gene. These genetic changes reduce the amount of type I collagen produced in the body, though the molecules that are produced are normal.

Is Oi a disability?

Most people with OI experience physical disability. OI also can cause weak muscles, brittle teeth, a curved spine, and hearing loss. Most forms of OI are caused by abnormal genes that are passed down from one or both parents to their children. There are currently 11 types of OI.
