title: [Phylogenetic analysis of ancient mitochondrial DNA lineages of human remains found in Yakutia].
abstract: Molecular genetic analysis of ancient human remains are mostly based on mitochondrial DNA due to its better preservation in human skeletons in comparison with nuclear DNA. We investigated mtDNA extracted from human skeletons found in graves in Yakutia to determine their haplotypes and to compare them with lineages of modern populations. Ancient DNA was extracted from fragments of three skeletons of Yakut graves at At-Dabaan, Ojuluun and Jaraama sites (dating XVIII century) and two skeletons of Neolithic graves at Kerdugen site found in central Yakutia (Churapchinsky, Kangalassky and Megino-Kangalassky districts of Yakutia). Five different haplotypes belonging to specific Asian haplogroups were identified. Lineages of mtDNA of Yakut graves belong to haplo-groups C4a, D5a2 and B5b. Our results indicate the continuity of mitochondrial lineages in the Yakut gene pool during the last 300 years. Haplotypes of two humans from Kerdugen site graves belong to haplogroups A4 and G2a/D. We compared these haplotypes with that of 40,000 Eurasian individuals, 900 of them from Yakutia. No exact matches were found in Paleoasian populations of Chukchi, Eskimos, Koryaks and Itelmen. Phylogenetically close haplotypes (+/- 1 mutation) were found in populations of Yakuts and Evenks, as well as in some populations of China, Southern and Western Siberia.
