Gaucher disease is an inherited disorder in the metabolism of fats.
In a person with Gaucher disease, a particular enzyme is missing. This enzyme is important in breaking down lipids, or fats, in the body. Because it is missing, a substance builds up in the body and causes damage to various organs. The most common form of the disease tends to be fairly mild. The spleen, the bones, and the blood cells are affected.
Gaucher disease is a genetic disorder. If both parents carry the gene for the disorder, their children are at risk.
