Tay–Sachs disease has become a model for the prevention of all genetic diseases. In the United States before 1970, the disease affected about 50–70 infants each year in Ashkenazi Jewish families. About 10 cases occurred each year in infants from families without identifiable risk factors.
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 ...
Dor Yeshorim (Hebrew: דור ישרים) also called Committee for Prevention of Jewish Genetic Diseases, is a nonprofit organization that offers genetic screening to members of the Jewish community worldwide. Its objective is to minimize, and eventually eliminate, the incidence of genetic disorders common to Jewish people, such as Tay–Sachs ...

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 most common mutation, which occurs in over 80 percent of Tay–Sachs patients, results from a four base pair addition (TATC) in exon 11 of the Hex A gene. This insertion leads to an early stop codon, which causes the Hex A deficiency. [12] Children born with Tay–Sachs usually die between two and four years of age from aspiration and ...

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 ...
