It occurs when a child inherits a flaw (mutation) in the HEXA gene from both parents. The genetic change that causes Tay … Zobacz więcej 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.

Witryna20 lis 2024 · Tay-Sachs disease belongs to the group of autosomal-recessive lysosomal storage metabolic disorders. This disease is caused by β-hexosaminidase A (HexA) enzyme deficiency due to various mutations in α-subunit gene of this enzyme, resulting in GM2 ganglioside accumulation predominantly in lysosomes of nerve cells.
