Gaucher disease
Glucocerebrosidase deficiency; Glucosylceramidase deficiency; Lysosomal storage disease - Gaucher; Gaucher's diseaseGaucher disease is a rare genetic disorder in which a person lacks an enzyme called glucocerebrosidase (GBA).
Causes
Gaucher disease is rare in the general population. People of Eastern and Central European (Ashkenazi) Jewish heritage are more likely to have this disease.
It is an autosomal recessive disease. This means that the mother and father must both pass one abnormal copy of the disease gene to their child in order for the child to develop the disease. A parent who carries an abnormal copy of the gene but doesn't have the disease is called a silent carrier.
Autosomal recessive
Autosomal recessive is one of several ways that a genetic trait, disorder, or disease can be passed down through families. An autosomal recessive dis...
Read Article Now Book Mark ArticleThe lack of the GBA causes harmful substances to build up in the liver, spleen, bones, and bone marrow. These substances prevent cells and organs from working properly.
There are three main subtypes of Gaucher disease:
- Type 1 is most common. It involves bone disease, anemia, an enlarged spleen and low platelets (thrombocytopenia). Type 1 affects both children and adults. It is most common in the Ashkenazi Jewish population.
- Type 2 usually begins in infancy with severe neurologic involvement. This form can lead to rapid, early death.
- Type 3 may cause liver, spleen, and brain problems. People with this type may live into adulthood.
Symptoms
Bleeding because of low platelet count is the most common symptom seen in Gaucher disease. Other symptoms may include:
-
Bone pain and fractures
Bone pain
Bone pain or tenderness is aching or other discomfort in one or more bones.

Exams and Tests
The health care provider will perform a physical exam and ask about the symptoms.
The following tests may be done:
- Blood test to look for enzyme activity
-

Treatment
Gaucher disease can't be cured. But treatments can help control and may improve symptoms.
Medicines may be given to:
- Replace the missing GBA (enzyme replacement therapy) to help reduce spleen size, bone pain, and improve thrombocytopenia.
- Limit production of fatty chemicals that build up in the body.
Other treatments include:
- Medicines for pain
- Surgery for bone and joint problems, or to remove the spleen
- Blood transfusions

Outlook (Prognosis)
How well a person does depends on their subtype of the disease. The infantile form of Gaucher disease (Type 2) may lead to early death. Most affected children die before age 5.
Adults with the type 1 form of Gaucher disease can expect normal life expectancy with enzyme replacement therapy.

Prevention
Genetic counseling is recommended for prospective parents with a family history of Gaucher disease. Testing can determine if parents carry the gene that could pass on the Gaucher disease. A prenatal test can also tell if a baby in the womb has Gaucher syndrome.

Gaucher cell - photomicrograph - illustration
Gaucher disease is called a lipid storage disease where abnormal amounts of lipids called glycosphingolipids are stored in special cells called reticuloendothelial cells. Classically, the nucleus is pushed off to the side and the remainder of the cell is filled with abnormal lipids.

Hepatosplenomegaly - illustration
Liver and spleen enlargement (hepatosplenomegaly) can occur as the result of an inherited disorder in which the liver cannot process glucocerebroside. The buildup of this substance in body tissues can cause severe damage to the central nervous system in infants.
