The mutation might then have been "reintroduced by recurrent gene flow from Ashkenazi populations to other Jewish, European, and North African populations. The present-day frequency of the mutation in control populations (0.05% in Europeans, 0.5% in North-African Arabs and 1% in Ashkenazi Jews) may support this scenario".) [43] [44]
There are many references to Ashkenazi Jews in the literature of medical and population genetics. Indeed, much awareness of "Ashkenazi Jews" as an ethnic group or category stems from the large number of genetic studies of disease, including many that are well reported in the media, that have been conducted among Jews.
A 2009 study was able to genetically identify individuals with full or partial Ashkenazi Jewish ancestry. [61] In August 2012, Legacy: A Genetic History of the Jewish People, a book by Harry Ostrer, concluded that all major Jewish groups share a common Middle Eastern origin. [133] Ostrer also refuted the Khazar hypothesis of Ashkenazi ancestry ...
In 2014, 19.8% of adult Israelis smoked, 26.3% in the Arab population and 18.4% in the Jewish population. 35% of non-smoking respondents to the World Health Survey reported that they had been exposed to passive smoking. Smoking is responsible for about 8,000 deaths in Israel every year, of which about 700 among passive smokers.
Familial dysautonomia is seen almost exclusively in Ashkenazi Jews and is inherited in an autosomal recessive fashion. Both parents must be carriers for a child to be affected. The carrier frequency in Jews of Eastern and Central European (Ashkenazi) ancestry is about one in 30, while the carrier frequency in non-Jews is unknown.
Ashkenazi Jews have a high incidence of Tay–Sachs and other lipid storage diseases. In the United States, about 1 in 27 to 1 in 30 Ashkenazi Jews is a recessive carrier. The disease incidence is about 1 in every 3,500 newborns among Ashkenazi Jews. [40] French Canadians and the Cajun community of Louisiana have an occurrence similar to the ...
FMF affects groups of people originating in the Levant or Eastern Mediterranean (hence its name); it is thus most prominent among those from or with ancestry from the regions including Arabs, Armenians, Jews (particularly Sephardi, Mizrahi, and to a lesser degree Ashkenazi Jews), and Turks.

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 ...
