HLA polymorphism in Israel. 2. Israeli Jews originating from Russia.

HLA typing of 123 Israel Jews of Russian origin showed a high frequency for HLA--A1, A2, Aw19 and B14, Bw16 and Bw35 of the A and B loci, respectively. The most frequently occuring haplotypes were (A1, B17), (Aw25, B18), (Aw26, Bw16), (Aw19, B13), (Aw23, B5) and (Aw25, Bw35). This study reveals a striking resemblance in the distribution of frequencies of HLA alleles and haplotypes between Russian Jews and two other East European Jewish communities (presented in this issue) of Polish and Rumanian origin.
