Haplogroup A22 is a branch on the maternal tree of humanity. Its age is not yet clear. Like its parent though, it traces its origin to Asia.

Research information comes from two published papers and a data set submitted directly to GenBank. One sample comes from an ethnic Han Chinese living in Colorado (Zheng et al., 2011). Two more samples come from a medical study. They do not include demographics, but the study was done in China (Liu et al., 2012). The last sample was directly submitted and comes from China (Jaing et al., 2014).

Geno 2 data does not include a member of this line.

Based on available information, this is definitely an East Asian and very likely a Chinese lineage.

mtDNA Haplogroup A22 Phylotree History 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 resuts over to build 17.

Geno 2.0 Data

Data from Geno 2.0 is derived from the The National Geographic Society’s Genographic Project — the DAR. The Hg ID is specific to this site and is used to protect the identities of those who take part in Genographic research. Birth Country, Mother's Birth Country, and Maternal Grandmother's Birth Country have been normalized from DAR database fields. The Maternal Origin is determined based on the three previous fields.

Note: Geno 2.0 results currently use Phylotree build 16. I am working on changing resuts over to build 17.
