AQHA registration revoked because of an DNA test mix up, mare was sold before the error could be set right. This is, however, her pedigree.
If her current owner would like to get the registration papers back (she was known as "Golden Girl U" and sold to south WY or Colorado in 2010 or 2011) he would only need to send a new hair sample in to AQHA for DNA testing. I think it's worth it!
