SuperDave, while there need to be 13 markers for acceptance into the FBI Offender database, only 10 markers are needed to get a sample accepted into the Forensic (crime scene) database. Being the prolific writer that you are on the subject, I am really surprised that you do not seem to be aware of such a simple fact.
The 10 marker profile obtained from JonBenet's panties, which by the way was NOT touchDNA, was sufficient to be accepted into the Forensic (crime scene) database and can in no way be considered to be a partial profile.
From the FBI factsheet:
https://www.fbi.gov/about-us/lab/biometric-analysis/codis/codis-and-ndis-fact-sheet
"Q: What are the minimum loci requirements for the STR DNA data submitted to NDIS?
A: The minimum CODIS Core Loci required for submission of DNA data to NDIS vary by specimen category. Generally, the 13 CODIS Core Loci are required for submission of convicted offender, arrestee, detainee, and legal profiles. The 13 CODIS Core Loci and Amelogenin are required for relatives of missing person profiles.
All 13 CODIS Core Loci must be attempted for other specimen categories with the following limited exceptions:
For forensic DNA profiles, all 13 CODIS Core Loci must be attempted but at least 10 CODIS Core Loci must have generated results for submission to and searching at NDIS.
For Missing Person and Unidentified Human Remains, all 13 CODIS Core Loci must be attempted."
It might interest you to know that in the UK and in much of Europe only 10 markers are required for their databases. So it would seem that most of Europe and the UK are happy to match only 10 marker profiles. Maybe you should write to them and tell them it isnt possible and try explaining why.

The 13 CODIS loci used in the U.S. are CSF1PO, FGA, TH01, TPOX, VWA, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, and D21S11 (7). The U.K. and much of Europe utilize 10 core loci that include the additional markers D2S1338 and D19S433 along with eight overlapping loci FGA, TH01, VWA, D3S1358, D8S1179, D16S539, D18S51, and D21S11.
