Tay Sachs Disease is a common Ashkenazi Jewish inherited disease with a carrier frequency of (1 in 30) and affects (1 in 3600) pregnancies.

Tay Sachs Disease: Autosomal recessive inheritance (25% if both parents are gene carriers) has been described.

Tay Sachs Disease is a fatal metabolic blood disease usually detected by age 6. A few cases of adult onset Tay Sachs have been described.


*The Ashkenazi Jewish Screen is available in a variety of Panels:

  • Basic Panel – 3 Diseases
  • Expanded Panel – 8 Diseases
  • *Full Panel – 18 Diseases (One company is running a 3 part Ashkenazi panel that has up to 39 diseases)

*The Full Panel is now also part of many Microarray Panels that can test for over 100 diseases.

The Jewish population is the United States as of 2012 was 6,543,820 making up 2.1% of the entire U.S. population (1).

The Ashkenazi Jewish Inherited Disease Panel was created to help screen for specific ethnic inherited diseases. Preconceptional testing is suggested to help identify or rule-out the parents as being carriers.
