If I am understanding this correctly, and based on a previous posts, L841-L848 were previously identified in a private WTY participant who was P338+. L840, however, was not previously identified in this P338+ individual. But the 1000 Genomes data suggests that L840 is also upstream from L22. So essentially none of these "new" SNPs (i.e., L841 - L848 for sure) will be of any value in further dissecting L22+ and/or P109+ folks, but is it still to early to tell if L840 will be of any surgical value?
