Out of 604 monitored pregnancies where there was a prenatal diagnosis of Tay–Sachs disease, 583 pregnancies were terminated. Of the 21 pregnancies that were not terminated, 20 of the infants went on to develop classic infantile Tay–Sachs disease, and the 21st case progressed later to adult-onset Tay–Sachs disease.

Although no cure for Tay–Sachs disease has been found, antenatal genetic screening has virtually eliminated the disease in the Ashkenazi Jewish population in both the United States and Israel. In 1979, Kaback served on the first National Institutes of Health (NIH) panel to recommend antenatal diagnosis in cases where a couple might be at risk ...
Tay–Sachs disease is inherited in an autosomal recessive pattern. The HEXA gene is located on the long (q) arm of human chromosome 15, between positions 23 and 24. 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 ...
Tay–Sachs disease has become famous as a public health model because an enzyme assay test for TSD was discovered and developed in the late 1960s and early 1970s, providing one of the first "mass screening" tools in medical genetics. It became a research and public health model for understanding and preventing all autosomal genetic disorders.

The cause of Tay–Sachs disease is a genetic defect that is passed from parent to child. This genetic defect is located in the HEXA gene, which is found on chromosome 15. The HEXA gene makes part of an enzyme called beta-hexosaminidase A, which plays a critical role in the nervous system.
