What is the deadliest genetic disorder?

Tay-Sachs. 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.
