What is Gaucher disease?

Gaucher (pronounced "go-shay") disease, also known as Gaucher's disease, is a genetic metabolic disorder that affects many of the organs within the body. The name of the disease comes from Philippe Gaucher, a French doctor who first described the disease in 1882.
The disease is somewhat rare, occurring in 1 in 40,000 births. In order for a child to have the disease, both parents must be carriers.
There are three types of Gaucher disease. Gaucher disease type 1, which is the most common, comes with the least problems, and can be treated. Gaucher disease type 2 is very rare, but causes neurological problems and is usually fatal. It is untreatable. Gaucher disease type 3 is rare in western countries. It is a mix between types 1 and 2, and can be treated.
