Dor Yeshorim

Dor Yeshorim (Hebrew: דור ישרים‎) also called Committee for Prevention of Jewish Genetic Diseases, is an 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 disease. Dor Yeshorim is based in Brooklyn, New York, but has offices in Israel and various other countries.

In both the Ashkenazi and Sephardi Jewish communities, there is an increased rate of a number of genetic disorders such as Tay–Sachs disease, an autosomal recessive disorder that goes unnoticed in carriers, but is fatal within the first few years of life in almost all homozygotes. (The exception is the rare adult-onset Tay–Sachs, which is normally not fatal but is incapacitating.)

Orthodox Judaism generally opposes selective abortion. Although preimplantation genetic diagnosis (PGD) is often approved by Halakha, it is a difficult and costly process. By avoiding marriages between "carriers", the incidence of the disorders decreases without having to resort to such methods.
