Haplogroup A21 is a branch on the maternal tree of humanity with a likely origin in Tibet or the surrounding region. Its age has not been determined.

Academic information comes from three studies of peoples in or near Tibet. The first study found a member of the lineage in Chamdo, Tibet (Qin et al., 2010). Another comes from GenBank samples from an unpublished study of the Ladakh tribe (Sharma V et al., 2012). Finally, the branch was found in the Sherpa people (Kang et al., 2013).

Interestingly, the Geno 2 data set includes someone whose maternal origins are from Trinidad and Tobago. The a likely explanation is that their ancestor was one of the thousands of Indians taken into indentured service by the British. They became known as Indo-Trinidadians.

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.
