  • Title: [Restriction polymorphism of the major noncoding region of mtDNA in the indigenous population of the TUVA republic].

    Journal: Genetika; 1999 Aug; 35(8):1124-31. PubMed ID: 10546115.
    Abstract:
    Mitochondrial DNA sequence variation was examined in three rural populations of the indigenous inhabitants from the Tuva Republic. The frequencies of restriction sites within the D-loop region of mtDNA were determined. The three populations studied demonstrated similar patterns of mtDNA polymorphism. Like other Siberian populations, Tuvinians were characterized by high frequencies of the HaeIII 16517 and AspS9I (Cfr13I) 16516 restriction sites (about 75%). Moreover, in Tuvinians, a relatively low (71 to 81%) frequency of the KpnI 16129 restriction site was observed. The frequency of the mitotype differing from the Cambridge sequence by the HaeIII 16517 and KpnI 16129 sites in Tuvinians was higher than in Mongols and Russians. The features of mtDNA polymorphism point to the similarity between Tuvinians and other Siberian ethnic groups (Sel'kups in particular). This can be explained by the contribution of the Samoyed component, along with the Turkic and Mongoloid ones, to the formation of the Tuvinian ethnic group.
