The phrase "12 markers" usually refers to a low-resolution Y chromosome test
for males. For mtDNA, the results are given as differences from the Cambridge
Reference Sequence (CRS).

Haplogroup X typically includes a "motif" (a common theme) of 16189C, 16278T,
and 16223T (plus other mutations that may vary from person to person).
Haplogroup X typically includes 16223T, 16290T, and 16319A. You can see that they
have one mutation in common, but also some differences. These would usually be
sufficient to assign the correct haplogroup, but that technique must not have
worked in your particular case, or else there was a clerical error. The
haplogroups for you and your maternal aunt should be the same.

Would you transfer your Genographic Project results to Family Tree DNA
(there's a link at the bottom of your personal page), and from there upload them to
MitoSearch (there will be a link on your personal page at FTDNA)? Then we can
discuss them more. After you've transferred your results, notify FTDNA about
the discrepancy.
