I was looking at the R1bP312xL21 Haplotypes spreadsheet created by Mike W in the DF27 Yahoo Group and he has done a great job of sorting the various subclades (and potential candidates) under P312. Of interest to me is the group that is potentially DF81+. Looking at the haplotypes, I see what looks like some very telling marker values that possibly identify DF81 individuals.
Those values are DYS458=16, DYS487=14 and possibly DYS449=28. A value of DYS439=11 also appears noteworthy. Of course these values are not a definitive indicator of DF81 as they have also been found in at least two R-U152 persons.
To date, there have been four persons of Iberian ancestry who tested positive for DF81. The surnames are Uriarte, Zúñiga, Tello, and Zambrano (my ancestral lineage). In the group of potential and confirmed DF81+ individuals, the surnames are a majority Iberian with many being Basque. Several non-Iberian descent individuals have tested negative. With the surnames that were confirmed positive it appears this may be emerging as a Basque subclade. More testing is needed and I would encourage those individuals who are R1b-P312 and especially in the subclade DF27 having this combination of markers to get themselves tested for DF81.
