"Jewish Genetic Diseases" is a term that describes a group of conditions which are unusually common among Jews of Ashkenazi (Central and Eastern European) descent. Although these diseases can affect Sephardi Jews and non-Jews, they appear in Ashkenazi Jews more often — as much as 20 to 100 times more frequently. There is no set panel of Jewish genetic disorders, and different labs screen for a different number of them. The most current recommendation comes from the American College of Medical Genetics (ACMG), and suggests screening for nine specific disorders.
