“…The low frequencies were observed in African populations and among Europeans living north of the Mediterranean region [2,3,8,13,15,23,24]. The highest EsD2 gene frequencies were found in Lapland, Japan and South Asia [4,8,9,14,24], In our investigation we have found that Ashkenazi and North African Jews present frequencies similar to those of European populations.…”

Esterase D Polymorphism in Several Population Groups in Israel

The genetic polymorphism of red blood cells esterase D (EsD) has been investigated in 9 population groups in Israel: Ashkenazi Jews, non-Ashkenazi Jews from North Africa, Iran, Turkey, Egypt, Balkan, Iraq, Yemen as well as Arabs living in Israel. The distribution of EsD¹and EsD²genes among the 9 communities was not homogenous (χ²= 42.3; d.f. = 8; p < 0.0005). The Ashkenazi and North African Jews had significantly lower frequencies of EsD²(0.100 and 0.102 respectively) than did Yemenite Jews and Arabs (0.212 and 0.206 respectively). The other communities investigated showed intermediate values. A Jewish family from Greece carrying the rare allele EsD³ has been detected.

Red cell esterase D (EsD) phenotypes were determined in a Danish population sample of 3,116 unrelated adults by starch-gel electrophoresis. A new phenotype was discovered, which appeared to be determined by the EsD¹ allele and a new allele EsD^cP^h. The gene frequencies observed were EsD¹ = 0.9007, EsD² = 0.0992, EsD^CPh = 0.0001. Investigation of 1,111 mother-child pairs and 59 families with 157 offspring added further support to the genetic model of two common alleles at an autosomal locus. The applicability of the EsD polymorphism to paternity testing was investigated on 960 cases of disputed paternity. An estimate of the EsD null allele frequency (0.001) in European populations was made on the basis of observations made on 5,864 mother/ child combinations and 762 matings with 1,882 offspring. The influence of this allele on the reliability of exclusions of paternity was determined.

“…ESD was initially phenotyped by conventional electrophoresis in starch gel using the technique of Kühnl et al |4] and in agarose gel by agarose gel elec trophoresis according to Bär et al |5) and Martin and Otto [8]. Isoelectric focusing was carried out on aga rose gels with pharmalytes (pH range 4.5-S.4) ac cording to Weidinger and Henke (3).…”
