mtDNA haplogroup U2d and medieval nomads

Mitochondrial haplogroup u2d phylogeny and distribution.

Malyarchuk B, Derenko M, Perkova M, Vanecek T.


The sequencing of the entire mitochondrial DNA belonging to haplogroup U2d reveals that this clade is defined by four coding-region mutations at positions 1700, 4025, 11893, and 14926. Phylogenetic analysis suggests that western Eurasian haplogroup U2d appears to be a sister clade with the Indo-Pakistani haplogroup U2c. Results of a phylogeographic analysis of published population data on the distribution of haplogroup U2d indicate that the presence of such mtDNA lineages in Europe may be mostly a consequence of medieval migrations of nomadic tribes from the Caucasus and eastern Europe to central Europe.
