Around one in 100 people in the general US population is a carrier for type I Gaucher's disease, giving a prevalence of one in 40,000. [40] Among Ashkenazi Jews, the rate of carriers is considerably higher, at roughly one in 15. [40] Type II Gaucher's disease shows no particular preference for any ethnic group. [citation needed]
Enzyme replacement therapy is available to treat mainly Fabry disease and Gaucher disease, and people with these types of sphingolipidoses may live well into adulthood. The other types are generally fatal by age 1 to 5 years for infantile forms, but progression may be mild for juvenile- or adult-onset forms.
They are generally inherited in an autosomal recessive fashion, but Fabry disease is X-linked. Taken together, sphingolipidoses have an incidence of approximately 1 in 10,000. Enzyme replacement therapy is available mainly to treat Fabry disease and Gaucher disease and people with these types of sphingolipidoses may live well into adulthood ...
Type C is the most common form of the disease [3] Type C2 is a rare form of the disease. [9] Niemann–Pick disease type D (or Nova Scotia form) is now believed to be the same condition as Niemann–Pick disease type C. [10] Two poorly characterized forms of Niemann–Pick disease have also been described as types E and F. [11]
Mutations in the glucocerebrosidase gene cause Gaucher's disease, a lysosomal storage disease characterized by an accumulation of glucocerebrosides in macrophages that infiltrate many vital organs. [19] [20] Mutations in the glucocerebrosidase gene are also associated with Parkinson's disease. [21] [22]
In Gaucher's disease, the enzyme glucocerebrosidase is nonfunctional and cannot break down glucocerebroside into glucose and ceramide in the lysosome. [1] Affected macrophages, called Gaucher cells, have a distinct appearance similar to "wrinkled tissue paper" under light microscopy, because the substrates build-up within the lysosome.
Imiglucerase is a medication used in the treatment of Gaucher's disease. [2] [3]It is a recombinant DNA-produced analogue of the human enzyme β-glucocerebrosidase. Cerezyme is a freeze-dried medicine containing imiglucerase, manufactured by Genzyme Corporation.
Miglustat is indicated to treat adults with mild to moderate type I Gaucher disease for whom enzyme replacement therapy is unsuitable. [14]In the European Union, miglustat (Opfolda), in combination with cipaglucosidase alfa, is a long-term enzyme replacement therapy in adults with late-onset Pompe disease (acid α‑glucosidase [GAA] deficiency).
