DefinitionBy Mayo Clinic staff
Gaucher's (go-SHAYZ) disease occurs when certain harmful fatty substances accumulate to excessive levels in your liver, spleen, lungs, bone marrow and, less commonly, brain. This accumulation of fatty material in tissues interferes with how your body works and may cause organ enlargement and bone pain.
Gaucher's disease is caused by a deficiency of the enzyme glucocerebrosidase, which helps the body process the fatty substance glucocerebroside. The disease is sometimes called glucocerebrosidase deficiency.
Gaucher's disease can occur at any age. It's most common in Jewish people of Eastern and Central European descent (Ashkenazi).
Treatment for Gaucher's disease may involve enzyme replacement and other therapies.
