PI polymorphism in Israel: report on six Jewish population groups.
A total of 1148 Israeli Jews was typed for PI and divided by areas of origin into six groups: Eastern Europe (n = 236), Central Europe (n = 156), Rumania (n = 158), Bulgaria (n = 215), North Africa (n = 229), and Middle East (n = 154). Frequencies of PI*M1 (0.74-0.77) in Jews of European countries were higher than 0.68 in Jews of N. Africa and 0.62 in Jews of the Middle East. PI*M2 frequencies were correspondingly lower in European Jews: 0.11-0.14 vs 0.19 and 0.20 in non-European Jews. PI*M3 frequency range was 0.07-0.11 in European Jews and was highest in Middle Eastern Jews (0.17). PI*Z was found in one MZ individual. PI*S was low (less than 0.01) except in Sephardi Jews of Bulgaria and N. Africa (0.016 and 0.015). A rare variant, PI*Elemberg, was observed in five individuals from different countries of origin. The present results are in accord with those of a previous study on some Israeli Jewish groups and on some other Middle Eastern groups.
