  • Many Unnamed Variants Are Defining SNPs For Haplogroups That FTDNA Is Unaware Of

    I've got my full Big Y 700 results today and my haplogroup has changed from R-M198 to R-Y879.

    However I need some advice, I apparently have 48 unnamed variants but I checked the positions of these on ISOGG's https://ybrowse.org/gb2/gbrowse/chrY/ and found out that in fact that this was only true for 22 of the mutations, the other 26 are already named and documented SNPs.

    Of these 26 named SNPs, 22 are defining mutations for the haplogroup R-Y34241 (according to Ybrowse) which is downstream of my current one, with 1 other SNP out of these 26 being a defining mutation for the haplogroup R-Y2568 which is upstream of my current group. The remaining 3 named variants do not currently define any haplogroups yet.

    However with regards to R-Y34241 which is downstream of my current haplogroup, it has 24 defining mutations according to https://www.yfull.com/tree/R-Y34241/, of which I have tested positive for 21 mutations, 2 of the positions gave no reading according to my Big Y data and 1 position did yield a positive reading for the mutation but it was a low quality reading so didn't count as confirmed.

    Do I need to email a staff member at FTDNA to update their SNP databases as well as inform them about my inaccurate haplogroup designation?

    I've already tabulated the SNP positions along with links to ISOGG's ybrowse for each one confirming that they are actually defined in an excel table, so it ought not even take them any time or effort to verify what they should already be aware of.

    As examples the following 21 SNPs that partly define R-Y34241 are currently listed as unnamed variants by FTDNA:

    Y34238

    Y34241

    Y34243

    Y34242

    Y34247

    Y34239

    Y34248

    Y34244

    Y34246

    Y34237

    Y34249

    Y34254

    Y35108

    Y34251

    Y34252

    Y35111

    Y34250

    Y34253

    Y34255

    Y35110

    Y35109

    I don't know how to edit posts so I will have to update here. After being advised by a helpful ISOGG volunteer, one should check here for pending variant submissions to ISOGG:

    https://isogg.org/wiki/FT_SNP_index

    It turns out that FTDNA are aware of 17 of my unknown variants and have submitted them to be reviewed for inclusion in the ISOGG Y haplotree as it is, so assuming they eventually update their databases I've only got 6 unknown variants outstanding.
