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.
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 ...
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 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 ...
It predominantly occurs in Ashkenazi Jews. It is the fourth most common coagulation disorder after von Willebrand's disease and haemophilia A and B . In the United States, it is thought to affect 1 in 100,000 of the adult population, making it 10% as common as haemophilia A. [ 1 ] [ 5 ]
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.
