| Abstract: | Serological polymorphism of HLA 1 class genes and antigens (A, B, C) was studied in native West-Siberian population of Khants. Genes HLA-A2, A23, A24, B7, B35, B49, Cw4 and Cw7 appeared to be most frequent in this population. HLA-A23/B49 was the most wide-spread haplotype with strong linkage disequilibrium. The main features of the HLA polymorphism indicate profound mongoloid roots of Khants, whereas strong linkage disequilibrium of some HLA alleles confirms the idea of the origin of Khants as a result of ancient mixing of mongoloids and caucasoids. |
