Gaucher disease (GD) is an autosomal recessive lysosomal storage disorder due to deficient activity of beta-glucocerebrosidase. As a result of this deficiency, there is intracellular accumulation of glucosylceramide (GlcCer, glucosylcerebroside) primarily within cells of mononuclear phagocyte origin, which are the characteristic 'Gaucher cells' identified in most tissues (Jmoudiak and Futerman, 2005). Gaucher disease is classically categorized phenotypically into 3 main subtypes: nonneuronopathic type I (GD1), acute neuronopathic type II (GD2; 230900), and subacute neuronopathic type III (GD3; 231000). Type I is the most common form of Gaucher disease and lacks primary central nervous system involvement. Types II and III have central nervous system involvement and neurologic manifestations (Knudson and Kaplan, 1962; Jmoudiak and Futerman, 2005). All 3 forms of Gaucher disease are caused by mutation in the GBA gene. There are 2 additional phenotypes that may be distinguished: perinatal lethal Gaucher disease (608013), which is a severe form of type II, and Gaucher disease type IIIC (231005), which also has cardiovascular calcifications. See also 610539 for a form of atypical Gaucher disease caused by mutation in the gene encoding saposin C (PSAP; 176801), which is an activator of beta-glucosidase.  http://www.omim.org/entry/230800

Gaucher disease is an inherited disorder that affects many of the body's organs and tissues. The signs and symptoms of this condition vary widely among affected individuals. Researchers have described several types of Gaucher disease based on their characteristic features.

Type 1 Gaucher disease is the most common form of this condition. Type 1 is also called non-neuronopathic Gaucher disease because the brain and spinal cord (the central nervous system) are usually not affected. The features of this condition range from mild to severe and may appear anytime from childhood to adulthood. Major signs and symptoms include enlargement of the liver and spleen (hepatosplenomegaly), a low number of red blood cells (anemia), easy bruising caused by a decrease in blood platelets (thrombocytopenia), bone abnormalities such as bone pain and fractures, and joint conditions such as arthritis.

The most severe type of Gaucher disease is a very rare form of type 2 called the perinatal lethal form. This condition causes severe or life-threatening complications starting before birth or in infancy. Features of the perinatal lethal form can include extensive swelling caused by fluid accumulation before birth (hydrops fetalis); dry, scaly skin (ichthyosis) or other skin abnormalities; hepatosplenomegaly; distinctive facial features; and serious neurological problems. As its name indicates, most infants with the perinatal lethal form of Gaucher disease survive for only a few days after birth.

Types 2 and 3 Gaucher disease are known as neuronopathic forms of the disorder because they are characterized by problems that affect the central nervous system. In addition to the signs and symptoms described above, these conditions can cause abnormal eye movements, seizures, and brain damage. Type 2 Gaucher disease usually causes life-threatening medical problems beginning in infancy. Type 3 Gaucher disease also affects the nervous system, but it tends to worsen more slowly than type 2.

Another form of Gaucher disease is known as the cardiovascular type (or type 3c) because it primarily affects the heart, causing the heart valves to harden (calcify). People with the cardiovascular form of Gaucher disease may also have eye abnormalities, bone disease, and mild enlargement of the spleen (splenomegaly).  https://medlineplus.gov/genetics/condition/gaucher-disease
