Human mtDNA Phylogeny

  1. MtDNA Community aims to track complete mtDNA sequences. Accordingly, it is currently (5 Apr 2012) tracking a total of 12,813 complete mtDNA sequences posted in NCBI. The criteria for inclusion a sample in mtDNA Community includes:
    1. Complete mtDNA sequences. In that case mitogenomes posted in NCBI that contain only coding region information were not included.
    2. Databases which contains no errors. For complete list of included databases click here.
  2. The phylogeny is presented as an expandable structure that can be navigated through using the "+" and "–" signs at its bifurcations.
  3. You can also navigate throughout the phylogeny by using the search by position/ haplogroup/ sample name options.
  4. The skeleton of the phylogeny is identical to PhyloTree build 14. You can download an XML version of the phylogeny. Based on this structure mtDNA Community interpret the complete mtDNA sequences stored in it for haplogroup labels, private mutations, phylogenetically expected but missing mutations and in its web-based version shared private mutations between stored samples to allow further resolution of the phylogeny.
  5. Click on any haplogroup name to see all samples currently falling under this haplogroup.
  6. An excel based comparison of all 12,813 samples and the RSRS, and their interpretation by mtDNAble is available here.
  7. Information about country of origin, geography and ancestry is gradually being incorporated into the sample information when available.
