[Genetic HLA system in the Northern Khant population compared with other Ugro-Finnish peoples].

The northern khants different from the east khants in frequencies of some genes from the HLA-A, B, Cw system and in the absence of the disequilibrium linkage. Population-genetic mechanisms underlying HLA polymorphism differences between the two groups of khants which may have resulted during the historical development of these groups or from the difference of climate conditions under which these ethnic groups had lived, are under discussion.
