P312** guys, I'd like to make you aware of two developments:
I found three new SNPs (Z1897, Z1898, Z1899) in two P312** 1000 Genome Project samples, one from Colombia (HG01461) and the other from CEU (NA12347). The scores were lower than some of the other Z-series SNPs, but the fact that all three are found in the same two samples and in no other groups (U152, L21, Z196, etc.) is encouraging.
Also, last month, the anonymous researcher found DF27. While this SNP will probably not make it's way to the phylogenetic tree any time soon because of it's volatility (it has some back mutations in some samples and is heterozygous in others), it is interesting because it seems to be the parent SNP of both Z196 and Z225/Z229. If nothing else, it reinforces the importance of Z196 in Iberia.
That would be great find an SNP upstream of Z196 as it is scattered bunch of folks. I believe RRocca is saying DF27+ Z196- is found in someone of Iberian descent as well as the DF27+ Z196+ testee.
Unfortunately, if DF27 is unstable, it'll be hard to use.
