Gaucher Disease (GD) is an inherited condition that can damage many different parts of the body. Damage occurs when a type of fat — glucocerebroside — builds up in certain organs in the body.

GD typically causes a large liver and spleen, anemia, low platelet count, lung disease, and sometimes brain disease.

There are three basic types of GD. Type 1 (GD1) causes nearly all of the symptoms listed above, except for brain disease. GD2 and GD3 cause all the listed symptoms, including effects on the brain. GD2 is the most severe, with symptoms beginning before age 2. In GD3, the symptoms may begin before age 2, but are more mild and slower to worsen.
