Gaucher's Disease is a rare genetic disorder that affects the storage of fat in the body. It is also known as glucocerebrosidase deficiency, Gaucher disease, and lipid storage disorder. This disease is caused by the mutation of the GBA gene, which leads to the accumulation of fatty substances in the liver, spleen, bones and bone marrow. Other synonyms for Gaucher's Disease include Gaucher's Syndrome, Type 1 Gaucher's Disease, Type 2 Gaucher's Disease, and Type 3 Gaucher's Disease. Treatment for this disease may include enzyme replacement therapy, bone marrow transplantation, or surgery to remove the spleen.
