The National Gaucher Foundation (United States) states the incidence of Gaucher's disease is about one in 20,000 live births. [39] 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 ]
For example, two mutations in the glucocerebrosidase gene each cause Gaucher's disease in Ashkenazim, which is that group's most common genetic disease, but only one of these mutations is found in non-Jewish groups. [5] A few diseases are unique to this group; familial dysautonomia, for example, is almost unknown in other peoples. [5]
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.
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
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.
Velaglucerase alfa, sold under the brand name Vpriv, is a medication used for the treatment of Gaucher disease Type 1. [1] It is a hydrolytic lysosomal glucocerebroside-specific enzyme, which is a recombinant form of glucocerebrosidase. It has an identical amino acid sequence to the naturally occurring enzyme. [2] It is manufactured by Shire plc.
Osteonecrosis is also associated with cancer, lupus, sickle cell disease, [11] HIV infection, Gaucher's disease, and Caisson disease (dysbaric osteonecrosis). [1] [12] Bisphosphonates are associated with osteonecrosis of the mandible (jawbone). [13] The condition may also occur without any clear reason. [1]
Pompe disease was the first disease to be identified as an lysosomal storage disease in 1963, with L. Hers reporting the cause as a deficiency of α-glucosidase. Hers also suggested that other diseases, such as the mucopolysaccharidosis, might be due to enzyme deficiencies. [citation needed]
