Age: 2,419.2 ± 1,679.0; CI=95% (Behar et al., 2012b)
Origin: East Asia
Mutations: A13221G
Parent Branch: A5a1a1
Descendant branch(s):


Haplogroup A5a1a1a is an East Asian branch on the maternal tree of human kind. The woman who founded this line lived between 700 and 4,100 years ago (Behar et al 2012b).

Members have been found in two research studies. In both, the maternal origin was Japan. (Tanaka et al., 2004 and Bilal et al., 2008)

Geno 2 data does not yet include a member of this lineage.

While the line to date has only been seen in Japan, it is possible that it will be found on mainland East Asia in the future.

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 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.
