  • Title: [Restriction polymorphism of the major non-decoding region of mitochondrial DNA in human populations from the Volga-Ural region].
    Author: Khusnutdinova EK, Viktorova TV, Fatkhlislamova RI, Khidiatova IM.
    Journal: Genetika; 1999 May; 35(5):695-702. PubMed ID: 10495954.
    Abstract:
    The restriction fragment length polymorphism (RFLP) of the major noncoding region of mitochondrial DNA (mtDNA) was studied in the Bashkir (N = 217), Tatar (N = 57), Chuvash (N = 44), Mari (N = 52), Mordovian (N = 55), Udmurt (N = 62), and Komi (N = 45) populations. Of seven polymorphic AvaII, BamHI, EcoRV, KpnI, and RsaI restriction sites, five were found in Bashkirs and Tatars, and four were found in each of the other populations. In total, 13 mitotypes were detected, and only three of them were common to all populations from the Volga-Ural region. The parameters of gene diversity were calculated with respect to the polymorphic sites and mitotypes. Comparison with published data revealed both Mongoloid and Caucasoid components in the gene pool of the modern populations from the Volga-Ural region. The Mongoloid component was prevalent in the mitochondrial gene pool, which is consistent with historical, anthropological, and ethnographic data.
