Tay–Sachs disease is a genetic disorder that results in the destruction of nerve cells in the brain and spinal cord. [1] The most common form is infantile Tay–Sachs disease, which becomes apparent around the age of three to six months of age, with the baby losing the ability to turn over, sit, or crawl. [1]
The diseases are better known by their individual names: Tay–Sachs disease, AB variant, and Sandhoff disease. Beta-hexosaminidase is a vital hydrolytic enzyme, found in the lysosomes, that breaks down lipids. When beta-hexosaminidase is no longer functioning properly, the lipids accumulate in the nervous tissue of the brain and cause problems.

The CIGNA panel is available for testing for parental/preconception screening or following chorionic villus sampling or amniocentesis and tests for Bloom syndrome, Canavan disease, cystic fibrosis, familial dysautonomia, Fanconi anemia, Gaucher disease, mucolipidosis IV, Neimann-Pick disease type A, Tay-Sachs disease, and torsion dystonia.
[11] [12] Treating genetic problems is the mission of the Clinic for Special Children in Strasburg, Pennsylvania, which has developed effective treatments for such problems as maple syrup urine disease, a previously fatal disease. The clinic is embraced by most Amish, ending the need for parents to leave the community to receive proper care for ...
The main members of this group are Niemann–Pick disease, Fabry disease, Krabbe disease, Gaucher disease, Tay–Sachs disease and metachromatic leukodystrophy. They are generally inherited in an autosomal recessive fashion, but notably Fabry disease is X-linked recessive.
In 2008, researchers in Texas identified the hexosaminidase A deficiency known in humans as Tay–Sachs disease in four Jacob lambs. [31] [32] Subsequent testing found some fifty carriers of the genetic defect among Jacobs in the United States. [33] The discovery offers hope of a possible pathway to effective treatment in humans.
