    S8387 problematic in R1b-Z18 SNP Pack

    FTDNA's official documentation includes S8387 in the R1b-Z18 SNP Pack. Kit 220636 ordered the R1b-Z18 SNP Pack and received a classification of R-ZP85, so he phylogenetically needs an S8387 result; but that SNP is shown in blue ("Test Available") on his haplotree.

    S8387 is equivalent to DF95. From what I see kit 220636 is DF95+ and that supports the phylogeny for his ZP85 classification. S8387 gives a no-call when DF95 is positive.

    Note that S8387-S8388 are actually a single MNP. Having the two bases change at once may not be correctly captured by FTDNA's software. I'll check with Carlos and see about this. All items on this particular pack are managed by Peter.

    I had some on mine N113442 that showed tested negative, then directly connected downstream showed presumed positive, and then right downstream showed tested positive, messages Peter at the Z-18 tribe website, but haven't heard back yet
