The frequencies of HLA locus A, B and C antigens were determined in a previously unstudied population, the Zoroastrians. The phenotype and gene frequencies for this group are presented and contrasted with the distribution of HLA antigens among the Iranian Moslems. Comparison of the HLA profiles of these two Iranian populations suggests that the present Zoroastrians are a distinct group.
The distribution of 24 histocompatibility antigens in 88 Azerbaijani patients with leprosy was determined and compared with those of 125 normal, ethnically matched individuals. HLA-BW35 was increased in frequency among the Kurdish patients as compared to the controls; HLA-A1, however, displayed decreased frequency in patients with the lepromatous form of the disease. Among the Turks, diminished frequency of HLA-BW15 was noted in the total patient population. None of these comparisons, however, reached statistical significance when corrected for the number of antigens tested. Across the two ethnic groups, differences in the frequencies of HLA antigens between the patients and the controls were only marginal.
The distribution of HLA phenotype, genotype and haplotype frequencies was studied in two Iranian populations, the Armenians and the Jews. Although the frequencies of most antigens in the Armenians have approximately the average Jewish values, haplotype frequencies are quite different between the two populations. The frequencies of antigens in Iranian Jews are more similar to those in the Mazandaranies, a group of non-Jewish Iranians, than to the Jewish populations from Yemen and Cochin, India.
