This set of advantages has led to Ashkenazi Jews in particular being used in many genetic studies, not just in the study of genetic diseases. For example, a series of publications on Ashkenazi centenarians established their longevity was strongly inherited and associated with lower rates of age-related diseases. [ 11 ]
Bloom syndrome (often abbreviated as BS in literature) [1] is a rare autosomal recessive genetic disorder characterized by short stature, predisposition to the development of cancer, and genomic instability. BS is caused by mutations in the BLM gene which is a member of the RecQ DNA helicase family.
Familial dysautonomia (FD), also known as Riley–Day syndrome, is a rare, [2] progressive, [3] recessive genetic disorder of the autonomic nervous system [2] that affects the development and survival of sensory, sympathetic, and some parasympathetic neurons in the autonomic and sensory nervous system.
Most genetic studies of Ashkenazi Jews conclude that the male lines were from the Middle East. [158] [159] [160] A 2000 study by Hammer et al. [161] found that the Y-chromosome of Ashkenazi and Sephardic Jews contained mutations that are also common among Middle Eastern peoples, but uncommon among indigenous Europeans. This suggests that ...
In a study of Israeli Jews from some different groups (Ashkenazi Jews, Kurdish Jews, North African Sephardi Jews, and Iraqi Jews) and Palestinian Muslim Arabs, more than 70% of the Jewish men and 82% of the Arab men whose DNA was studied had inherited their Y chromosomes from the same paternal ancestors, who lived in the region within the last ...
Ashkenazi Jews carry a particularly high burden of disease-causing genetic mutations, such as those in the Ancient DNA from the teeth of 14th-century Ashkenazi Jews in Germany already included ...
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 ...
Hackers have compiled a giant apparent list of people with Ashkenazi Jewish ancestry after taking that information from the genetic testing service 23andMe, which is now being shared on the internet.
