title: Genetic polymorphism of delta-aminolevulinate dehydrase in several population groups in Israel.
abstract: The genetic polymorphism of red cell delta aminolevulinate dehydrase (ALADH) has been investigated in several population groups in Israel: Ashkenazi Jews, non-Ashkenazi Jews from North Africa, Egypt, Turkey, Iraq, Iran, Yemen and the Balkans, and Arabs. The distribution of the ALADH genes was not homogeneous (chi 2 = 36.83; d.f. = 8; p less than 0.0005). A significantly higher frequency of the ALADH2 gene was observed among the Ashkenazi Jews (0.2021) than among the non-Ashkenazi Jews and Arabs (gene frequencies 0.0825-0.1290) or all the other population samples so far studied (Liberia, Japan, Italy, Germany and Spain).
