3. Transmission

Tay-Sachs is a very rare disease because it can only be transmitted to a child when both parents carry the defective gene. A child who inherits one Tay-Sachs gene from each parent (two Tay-Sachs genes total) does not produce functional HEXA enzymes. Thus, he or she is certain to eventually develop Tay-Sachs disease.

Tay-Sachs disease is only transmitted genetically. The disease cannot be passed to a partner sexually or through any other non-inherited means. Therefore, a person who has the disease is not “contagious” to those around him or her.
