Tay-Sachs Carrier Screening

Carrier screening in the UK

Genetic carrier screening is a process of systematically offering a carrier test to a whole population (or sub-population) of healthy people, for a gene that is known to be common in that group.

In the UK, screening for Tay-Sachs disease in the Ashkenazi Jewish population is NHS-funded. People of Ashkenazi Jewish descent have a 1 in 25 chance of being a healthy carrier of Tay-Sachs disease. If you have one or more grandparents of Ashkenazi Jewish descent, there are two different ways to have Tay-Sachs carrier screening


If you have Ashkenazi Jewish ancestry, or a family history of Tay-Sachs disease and/or you have Tay-Sachs carriers in your family, you can ask your GP to refer you to your local NHS Genetics service for a Genetics appointment for Tay Sachs carrier testing alone – this test is free. If you live within the Kennedy Galton Centre catchment area (North West London, Hertfordshire or Bedfordshire) your GP should use this referral form

Barnet General Hospital

The Department of Chemical Pathology offers a screening service on Thursday mornings. The service is by appointment only and participants will need to be referred via their GP to genetics for the Tay Sachs test. Participants will only be able to book to give a blood sample once they have seen a genetic counsellor. Click here for further details
