Tay-Sachs disease incidence in French Canadians
A mutation that is not connected to the dominant Ashkenazi mutation, a deletion of a long sequence occurs with similar frequency in families of French-Canadian descent and has the same pathological effects. Since the Ashkenazi Jewish population, the population grew rapidly from a small French Canadian based group and remained isolated from the surrounding population by geography, culture and language barriers. In the early days of the Tay-Sachs were research, mutations in these two populations to be identical. Some researchers have argued that a productive Jewish ancestors introduced the mutation in the French Canadian population. This theory is called a "Jew Fur Trader Hypothesis" between the researchers announced in population genetics. However, assessment has shown that further research two mutations are not linked, and pedigree analysis has mutated into one of the founders of French-Canadian family, in southern Quebec in the 17th Century lived depicted.
Incidence of Tay-SachsAmong the Cajuns in Louisiana
The mutation found in Ashkenazi Jewish population occurs in southern Louisiana, Cajun, an ethnic group in America, which has been isolated for several hundred years because of the different languages. Researchers have the airlines for several families from Louisiana for one pair of creation does not pursue knows who is Jewish, who lived in France in the 18th Century.
