Haplogroup X2n is a branch on the maternal tree of humanity. It has a strong presence in Europe in modern populations.


Behar et al., 2012b did not include an age for this branch. However, based on analyis from YFull, it likely dates to the Upper Paleolithic or the last ice age.


Based on its age and where it is found today, the origin of X2n is most likely to be Western Eurasia.

Modern Distribution

X2n has wide distribution across southern and parts of eastern Europe. It is found in the Czech Republic, Italy, European Russia, and Greece.

mtDNA Haplogroup X2n Data Sources

GenBank Samples

GenBank is a database of genetic sequence data. It is run by the United States National Institute of Health. It serves as the main repository for mtDNA full sequence profiles. Samples come both from published academic literature and donations from genetic genealogy community members. In addition to GenBank samples, listings below may include other samples published but not submitted to GenBank such as those from the HapMap project.

Note: GenBank results currently use Phylotree build 16. I am working on changing results over to build 17.
