What We Know About the 3 Types of Gaucher Disease

Jan 04,  · The major clinical symptoms include: Enlargement of the liver and spleen (hepatosplenomegaly). A low number of red blood cells (anemia). Easy bruising caused, in part, by a low level of platelets (thrombocytopenia). Bone disease (bone pain and fractures). Here are some factors scientists have identified about genetic mutations associated with Gaucher disease: Having 2 copies of the LP mutation causes neurological symptoms and is related to Gaucher disease types 2 and 3. Patients with 1 copy of an NS mutations plus another mutation almost.

If too many lipids gaicher in your body, this can lead to:. They can include:. The disease is caused by a deficiency of the diseaes glucocerebrosidase, which is found in our tissue and is needed in order for your body diwease process and break down glucocerebroside, a fatty substance used in making blood cells.

This enzyme deficiency is, in turn, caused by a genetic mutation that comes from both of your parents. Type 1 is also the mildest form of the disease in terms of symptoms.

Description

Types of Gaucher Disease. Type 1: Gaucher disease type 1 makes up the majority of cases in western countries. Symptoms and signs can include bone and organ problems, but brain Type 2: Also called acute infantile neuronopathic Gaucher disease, Gaucher disease type 2 has an onset of central. 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. Apr 04,  · Causes Gaucher’s disease happens because of a recessive mutation in a gene called GBA. GBA is located on chromosome 1. Humans normally have two .

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 , lung disease, and bone abnormalities such as bone pain, fractures, and arthritis. 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. The most severe type of Gaucher disease is 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.

Another form of Gaucher disease is known as the cardiovascular type 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.

Gaucher disease occurs in 1 in 50, to , people in the general population. Type 1 is the most common form of the disorder; it occurs more frequently in people of Ashkenazi eastern and central European Jewish heritage than in those with other backgrounds. This form of the condition affects 1 in to 1, people of Ashkenazi Jewish heritage.

The other forms of Gaucher disease are uncommon and do not occur more frequently in people of Ashkenazi Jewish descent. Mutations in the GBA gene cause Gaucher disease. The GBA gene provides instructions for making an enzyme called beta-glucocerebrosidase. This enzyme breaks down a fatty substance called glucocerebroside into a sugar glucose and a simpler fat molecule ceramide.

Mutations in the GBA gene greatly reduce or eliminate the activity of beta-glucocerebrosidase. Without enough of this enzyme, glucocerebroside and related substances can build up to toxic levels within cells. Tissues and organs are damaged by the abnormal accumulation and storage of these substances, causing the characteristic features of Gaucher disease. This condition is inherited in an autosomal recessive pattern , which means both copies of the gene in each cell have mutations.

The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
