Mitochondrial DNA sequence variation in the Anatolian peninsula (Turkey)

Mitochondrial DNA sequence variation in the Anatolian peninsula (Turkey)

Received: 24 June 2003  Revised: 4 November 2003  

 Throughout human history, the region known today as the Anatolian peninsula (Turkey) has served as a junction connecting the Middle East, Europe and Central Asia, and, thus, has been subject to major population movements. The present study is undertaken to obtain information about the distribution of the existing mitochondrial D-loop sequence variations in the Turkish population of Anatolia. A few studies have previously reported mtDNA sequences in Turks. We attempted to extend these results by analysing a cohort that is not only larger, but also more representative of the Turkish population living in Anatolia. In order to obtain a descriptive picture for the phylogenetic distribution of the mitochondrial genome within Turkey, we analysed mitochondrial D-loop region sequence variations in 75 individuals from different parts of Anatolia by direct sequencing. Analysis of the two hypervariable segments within the noncoding region of the mitochondrial genome revealed the existence of 81 nucleotide mutations at 79 sites. The neighbourjoining tree of Kimura’s distance matrix has revealed the presence of six main clusters, of which H and U are the most common. The data obtained are also compared with several European and Turkic Central Asian populations.

Unfortunately I can’t access the pdf, but the core information is that the haplogroups present are…

  • H,  33.3%
  • U,  36%
  • K,   5.3%
  • U2, 1.3%
  • U5, 2.6%
  • J,     8%
  • T,  1.3%
  • M,  10.6%
  • W,  1.3%

  1. U(xU2,U5,K) is 36%?!

    I’m quite intrigued what subclades may it be made of. U4 is relatively frequent in Bulgaria but I suspect a higher diversity and would like to know more fine detail for this 1/3 of Antolian lineages.

    And what about a 10% of M? What M? M1 probaly but how much? Other types?
