Tay-Sachs disease (TSD) is a fatal genetic disorder that results in progressive destruction of the nervous system. It is caused by gene defects that lead to the absence of a vital enzyme called hexosaminidase-A (Hex-A). Carriers of the defective gene have a 50% chance of passing the gene to their children.

Tay–Sachs disease is an autosomal recessive genetic disorder, meaning that when both parents are carriers, there is a 25% risk of giving birth to an affected child with each pregnancy. The affected child would have received a mutated copy of the gene from each parent. If a child received a normal copy from one parent and a mutated copy from the other, it is a carrier.
