Gaucher Disease

What is Gaucher Disease?

Gaucher (go-SHAY) disease is a rare, inherited genetic disorder. While Gaucher disease is rare, it is one of the most common of what are called lysosomal storage disorders. These are disorders in which the body does not make certain enzymes as it should. People with Gaucher disease do not make enough of the enzyme glucocerebrosidase (GCase). Without this enzyme, Gaucher fat cells build up in the spleen, liver, and bone marrow. Gaucher disease is caused by a change (mutation) in the GBA gene. Both parents have to carry and pass on the mutation for their baby to develop Gaucher disease. About 6,000 people in the United States are living with the condition.(1-3)
