What did the Ashkenazi Jews have to do with the Tay-Sachs disease?

Tay-Sachs disease is a genetic disorder that is more prevalent among Ashkenazi Jews due to a higher carrier rate of the gene mutation responsible for the condition. This increased frequency is attributed to historical population bottlenecks and founder effects within the Ashkenazi community. As a result, genetic screening for Tay-Sachs is often recommended for individuals of Ashkenazi descent, especially when considering family planning, to identify carriers and reduce the risk of having affected children.
