Gaucher Disease


Gaucher disease is one of the inherited metabolic disorders known as lipid storage diseases.  Lipids are fatty materials that include oils, fatty acids, waxes, and steroids (such as cholesterol and estrogen).

People with Gaucher disease either do not produce enough of the enzyme glucocerebrosidase needed to break down lipids or have enzymes that do not work properly.  Fatty materials can accumulate in the brain and other organs.

General symptoms may begin in early life or adulthood and include skeletal disorders and bone lesions that may cause pain and fractures, enlarged spleen and liver, liver malfunction, anemia, and yellow spots in the eyes.

There are three common clinical subtypes of Gaucher disease:

  • Type 1 (or nonneuropathic) typically does not affect the brain.  Symptoms may begin early in life or in adulthood.  People in this group usually bruise easily due to low blood platelets and experience fatigue due to anemia  They also may have an enlarged liver and spleen. Many individuals with a mild form of the disorder may not show any symptoms.
  • Type 2 Gaucher disease (acute infantile neuropathic Gaucher disease) symptoms usually begin by 3 months of age and includes extensive brain damage, seizures, spasticity, poor ability to suck and swallow, and enlarged liver and spleen. Affected children usually die before 2 years of age.
  • Type 3 (or chronic neuropathic Gaucher disease) includes signs of brain involvement, seizures, skeletal  irregularities, eye movement disorders, cognitive deficit, poor coordination, enlarged liver and spleen, respiratory problems, and blood disorders.

Enzyme replacement therapy is very beneficial for type 1 and most type 3individuals with this condition. Successful bone marrow transplantation can reverse the non-neurological effects of the disease, but the procedure carries a high risk and is rarely performed in individuals with Gaucher disease.  People with Gaucher disease type 1 are at increased risk for Parkinson’s disease and Lewy Body Dementia. Gaucher disease type 2 is usually fatal by age 2.  People with Gaucher type 3 may have a shortened life expectancy.


Treatment can prevent or lessen some symptoms of the disease. Enzyme replacement therapy is available for most people with types 1 and 3 Gaucher disease. Given intravenously every two weeks, this therapy decreases liver and spleen size, reduces skeletal abnormalities, and reverses other symptoms of the disorder.

The U.S. Food and Drug Administration has approved eligustat tartrate for Gaucher treatment, which works by administering small molecules that reduce the action of the enzyme that catalyzes glucose to ceramide. Surgery to remove the whole or part of the spleen may be required on rare occasions, and blood transfusions may benefit some anemic individuals. Other individuals may require joint replacement surgery to improve mobility and quality of life. There is no effective treatment for severe brain damage that may occur in persons with types 2 and 3 Gaucher disease.
