Tay-Sachs Disease Underlying Cause
Tay-Sachs disease is a hereditary illness. The body does not make a molecule that is required to break down fatty substances in the body, called gangliosides. The gangliosides collect in the nervous tissue, resulting in damage to the brain and nerves. Tay-Sachs disease is an autosomal recessive disease. This means that it takes two mutant genes, one from each parent, to cause the disease.
