Tay-Sachs disease is caused by mutations in the HEXA gene located on the long arm of chromosome 15 at position 23. The mutation prevents the lysosome from functioning property, thereby resulting in accumulation of a fatty substance called GM ganglioside. Tay Sachs disease requires two copies of the mutated allele.

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.
