As a carrier, you will want to alert close family members to be tested. It is especially important for your spouse to be tested before you start a family. Prenatal diagnosis early on in pregnancy will predict if the fetus has Tay-Sachs disease. If the fetus is affected, the couple may choose to terminate the pregnancy. Artificial insemination with a confirmed non-carrier will eliminate the risk of passing the disease on to an offspring.
Adoption eliminates the risk of passing on the gene or the disease.
