Subject: SNP Testing - An R1a Surprise
Date: Thu, 23 Sep 2004 16:59:14 +0000
I am in communication with a fellow with "our" haplotype. Much to our suprise he came back R1a minus, with SNP testing via FTDNA. He was assigned to the "R" category (found most frequently in Central Asia). Who knows how many others would also find a "surprise" if SNP tested. I maintain, however, that he needs to be tested for R1a1 (M17) to rule out a back mutation somewhere upstream. This finding complicates the picture since most of us have used haplogroup predictors and been satisfied with the results. I now have no idea whether my uncle is R, R1a, R1a1 or whatever.
It would be great if you can do the tests at your lab. I will explore what can be done at the University of Edinburgh. We can coordinate things off List.
