The Komi (Komi‐Zyryan) people are one of the most numerous ethnic groups belonging to the Finno‐Ugric linguistic community. They occupy an extensive territory in north Russia to the west of the Ural Mountains, in the northeast of the East European Plain. This is an area of long‐term interactions between Europeans and North Asians. Genetic variability was evaluated in two geographically distinct populations, the Izhemski and Priluzski Komi. We searched for polymorphisms of the TP53 gene (a 16‐bp duplication in intron 3 and three RFLPs: for Bsh 1236I at codon 72, for Msp I in intron 6, and for Bam HI in the 3′ flanking region) and for variable number tandem repeat (VNTR) polymorphisms of locus D1S80 and of the 3′ untranslated region of the gene for apolipoprotein B ( ApoB ). Some data from our previous studies of TP53 , 3′ ApoB , and D1S80 variability were involved in the comparison of Komi with other Eastern European populations. Multidimensional scaling analysis of genetic distances was used for the evaluation of genetic relationships between populations. The results revealed some affinity between Priluzski Komi and Eastern Slavonic populations, and significant segregation of Izhemski Komi from other ethnic groups studied. The unique genetic features of Izhemski Komi may have been determined by their ethnogenesis or the pressure of environmental factors, such as special nutrition and adaptation to extreme climatic conditions.
