A12a

Haplogroup A12a is an Asian branch on the maternal tree of humanity.

Information about the lineage comes from two published study and a citizen science donated sample. The first study includes a lineage member from the Evenk people (Starikovskaya et al., 2005). The second includes someone from the Mansi people (Derenko et al., 2007). Both peoples are from Siberia. The citizen science donated sample does not have demographic information (Behar et al., 2012b).

Geno 2 data does not have a member from this line.

It is difficult to be sure with limited data, but this branch likely originates in Siberia.

mtDNA Haplogroup A12a Phylotree History

Phylotree.org is the maternal (mtDNA) tree of humanity. It is maintained by Dr. Mannis Van Oven. Each build is a major update to the tree. The current build is #17.

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.
