How are Gaucher cells formed?

Gaucher disease is inherited as an autosomal recessive disorder resulting from mutations at the glucocerebrosidase locus on chromosome 1q21. In this disorder, glucosylceramide (glucocerebroside) is stored in the reticuloendothelial system due to a deficiency of the lysosomal enzyme β-glucocerebrosidase [2].

Why does Gaucher happen?

Gaucher (go-SHAY) disease is the result of a buildup of certain fatty substances in certain organs, particularly your spleen and liver. This causes these organs to enlarge and can affect their function. The fatty substances also can build up in bone tissue, weakening the bone and increasing the risk of fractures.

Where is Gaucher disease from?

Gaucher disease is caused by changes (mutations) in the GBA gene. All three forms of Gaucher disease are inherited in an autosomal recessive pattern. Human traits, including the classic genetic diseases, are the product of the interaction of two genes, one received from the father and one from the mother.

How does Gaucher disease affect the body?

Gaucher disease is an inherited condition (passed down through families). It is a lysosomal storage disorder, a type of disease that causes fatty substances to build up in the bone marrow, liver and spleen. The fatty substances (sphingolipids) weaken bones and enlarge the organs, so they can’t work like they should.

What is pseudo Gaucher cell?

Pseudo-Gaucher cells are histiocytes with rounded, blue, lamellar cytoplasm resembling “onion skin” that can be found in up to 40% of the bone marrow of patients with CML. These are similar to glucocerebroside-stuffed histiocytes seen in Gaucher disease.

What organelle is affected by Gaucher disease?

Lysosomes are spherical intracellular organelles where many lipids and macromolecules are delivered for degradation by hydrolytic enzymes. Lysosomes are abundant in macrophages. The lysosomes in the macrophages of patients with Gaucher disease become progressively enlarged and filled with undigested glucocerebroside.

What type of mutation is Gaucher disease?

Gaucher disease is an autosomal recessive disease linked to mutations in the gene (GBA1) that encodes glucocerebrosidase; N370S (c. 1226A>G; p. Asp409Ser) is the most prevalent allele.

What are the types of Gaucher Disease?

There are three main forms of the disease: types 1, 2, and 3. No matter which kind it is, the reason you have Gaucher is that you were born with a change in one of your genes called a mutation.

How common is Gaucher’s disease?

Worldwide, Gaucher disease affects 1 in 40,000 people, but its frequency is as high as 1 in 450 people among Jews of Ashkenazi (Eastern European) descent. Although it is present at birth, symptoms can appear at any age.

Are Gaucher cells histiocytes?

Because of a congenital deficiency of β glucocerebrosidase, glucocerebroside deposits in the cytoplasm of histiocytes result in foamy histiocytes. Pseudo-Gaucher cells are histiocytes with cytoplasm containing needle-like inclusions, resembling Gaucher’s cells.

What is Gaucher disease biochemistry?

Gaucher disease (GD), a prototype lysosomal storage disorder, results from inherited deficiency of lysosomal glucocerebrosidase due to biallelic mutations in GBA. The result is widespread accumulation of macrophages engorged with predominantly lysosomal glucocerebroside.
