Medical genetics in Israel

Area of Science:

• Human Genetics
• Medical Genetics
• Population Genetics

Background:

• Israel's population comprises diverse subgroups, including Jewish and non-Jewish communities.
• Subgroups within Jewish and non-Jewish populations are distinguished by country of origin, religion, or village.
• Certain hereditary disorders occur with increased frequency in specific Israeli subgroups.

Purpose of the Study:

• To highlight the importance of precise patient origin in medical genetics within Israel.
• To underscore the role of genetic origins in identifying and managing hereditary disorders.
• To inform preventive genetic screening strategies based on population-specific risks.

Main Methods:

• Analysis of population structure in Israel, considering Jewish and non-Jewish communities.
• Review of reported hereditary disorders and their frequencies within distinct subgroups.
• Examination of genetic factors such as founder effect, genetic drift, and selection.

Main Results:

• Patient's precise origin is critical for medical geneticists in Israel.
• Increased frequencies of specific mendelian disorders are observed in various Israeli communities.
• Founder effect, genetic drift, and selection contribute to high frequencies of genetic disorders.

Conclusions:

• Understanding genetic origins is vital for medical geneticists in Israel.
• Knowledge of subgroup-specific hereditary disorders facilitates targeted genetic screening and research.
• Israel's medical genetics infrastructure supports both clinical service and research in human genetics.
