In Israel where Tay-Sachs is common they offer free screenings. How it works is once you are in the database you ask if a member of the opposite sex you are interested in is a match for you. If the match might result in the disease you are told so, however you are not told if it was you or the other person who has the gene.

Tay-Sachs is an autosomal recessive disease. Meaning that, if you are told that marriage to a particular person will result in 25% of the resulting children having Tay-Sachs, you BOTH have the faulty gene.
