Select DNA Testing Company: Use this option to select the company that tested your mtDNA. Select "Other" if you don't know the company. You may only select one test company.

Select HVR Region: If your test company tests for regions HVR1, HVR2, and/or HVR3, then check the appropriate box or boxes for the HVR regions for which you were tested. Note that you may check more than one box.

Note: The mtDatabase search engine will only search for results within your test company's range and only for results that have been sequenced over 75% of that range. Please see Locations and Regions for the ranges of different test companies. Please see the mtDatabase Statistics for information about the sequence lengths.

Search By Differences: Select the number of differences from your input values. The Results screen will then show matches with up to the selected number of differences.

Enter Values: Enter each location and base(A,G,C,T) value shown on your report. For deletions enter either "d", or "-", or ";" as the base. Values that are entered incorrectly will change to red. Note that HVR1 locations must be in the format "16xxx" and HVR2 and HVR3 locations must be in the format "xxx" and must fall within the selected lab's range.
