While Gaucher disease can affect anyone, it is especially common among people of Ashkenazi (Eastern European) Jewish descent. Researchers believe as many as 1 in 10 of this population are carriers. Carriers do not have Gaucher disease, but they can pass the Gaucher gene on to their children. Learn more about Gaucher disease carrier status.
Gaucher disease type 1 is the most common of several inherited Jewish genetic diseases that include Tay-Sachs disease and familial dysautonomia. The American College of Obstetricians and Gynecologists recommends special types of prenatal tests for Ashkenazi Jews.
Prenatal screening uses your genetic information and that of your partner to determine the overall probability that your child will have Gaucher disease. Doctors use saliva and blood tests to make this determination. Find out more about Gaucher disease inheritance and genetics.
If there is a known genetic mutation in the family, invasive testing via chorionic villus sampling (CVS) or amniocentesis (sampling womb fluid) can provide a prenatal diagnosis. Unlike genetic screening that analyzes parental DNA to determine the probability your child will have Gaucher disease, amniocentesis says for certain whether your child has the disease.
This kind of testing is uncommon, unless there is a familial history of Gaucher disease type 2. Many people with Gaucher disease type 1 have a very mild form of the disease with few to no symptoms at all. Prenatal testing is an ethically complicated personal decision, one that should involve discussion among parents, Gaucher experts and a genetic counselor.

Genetic counseling may be helpful you if you have Gaucher disease or are a carrier. A genetic counselor can help you:
- Understand the likelihood that your children will have Gaucher disease or be carriers
- Determine who else in your immediate family should undergo testing for Gaucher disease
- Coordinate with experts who specialize in Gaucher disease treatment
Does My Insurance Cover Prenatal Screening and Genetic Counseling?
Your insurance may cover the cost of prenatal screening and genetic counseling, especially if you have a family history of Gaucher disease. Physicians also recommend special prenatal tests if you are of Ashkenazi Jewish descent.
