Gaucher's disease

From SNPedia
(Redirected from Gaucher disease)

Gaucher disease Wikipedia is the most common type of lysosomal storage disease. It is caused by an enzyme deficiency that affects the liver and spleen as well as other organs. There are 3 clinical subtypes of Gaucher disease, types I, II, and III, with differing symptoms and treatments.

More than 300 mutations are known to occur in the GBA gene, which encodes the enzyme glucosylceramidase. About 1 in 15 Ashkenazi Jews carries a mutation that causes Gaucher disease; the rate in most other populations is much lower. Carriers are not affected; a child born with two copies of the same mutation, however, will develop Gaucher disease. [PMID 17878420]

These SNPs are most commonly associated with Gaucher disease:

  • Asn370Ser (also known as N370S) is associated with type I (nonneuropathic) disease
  • rs421016 and rs35095275 are associated with types II and III
  • Arg463Cys is associated with types II and III
  • rs104886460, also known as IVS2+1G-A

23andMe tests for the following SNPs that cause Gaucher disease. These SNPs are also associated with a higher risk of Parkinson's disease.

Gaucher's disease can be treated with an enzyme, but therapy is extremely expensive, and production problems have led to shortages of the drug. [1]
