What is Mitosearch?

Mitosearch is a public database for mitochondrial DNA results which helps genealogists determine if two or more people share a female ancestor on their direct maternal line. These results are also useful in inferring the likely geographic origin or ethnicity of a direct maternal line (Native American, African, European, Asian, etc). Mitosearch contains over 73,000 haplotypes mostly from Family Tree DNA customers, but also allows input of mtDNA results from other genetic genealogy testing companies including African Ancestry, AncestryDNA, Oxford Ancestors, Genographic Project (1.0), and Relative Genetics.

The database stores Hyper Variable Regions (HVR1 and HVR2) differences from rCRS and not the newer RSRS.

While it is almost always safe to share HVR1 and HVR2 results, you should not publicly share the results of a full sequence mtDNA test until a qualified consultant has confirmed your results are okay. Full sequence mtDNA test results may reveal medically significant information about you and all your mtDNA cousins.

Usage on WikiTree

When you enter or edit a mitochondrial DNA test, the optional field for mitosearch ID will appear.

This should be a combination of five letters or numbers, e.g. CPU47.
