      I have contacted http://www.britainsdna.com/ about U152* and if their Chromo2 YDNA test has any downstream SNPs not tested by Geno and FTDNA.

      I asked:

      "I am a U152* with no known downstream SNPs.

      I have tested negative to all known downstream SNPs from FTDNA and the latest Geno 2.0 chip!

      U152+ L2- Z36- Z56- Z192- Z194- CTS7193- F1493- PF4363-

      Do you test for any new SNP on your Chromo2 YDNA test other than the above?"

      Reply:

      "We test all of those, plus a number of others that could be useful, including S163, S209/Z42, S366/Z43 and 6 other new SNPs from sequences that we analysed. There may also be others originating from the recent Dutch Genome project!"

      More valuable than Geno for the Y then

        Well, keep this in mind:
        - At this point, nobody recieved their results from this test yet. Remember that there was a difference between the initial claims for Geno 2.0 and the actual results, as some important Y-SNP were missing and others did not work properly.

        - This test was specifically designed for BritainDNA clients. So it may not be so interesting for people who are not from north-western europe ancestry (specifically the British Isles and apparenly the Netherlands)

        That said, this test will certainly have one advantage. As it was designed recently, it will probably include a number of SNPs which were discovered after Geno 2.0 cutoff date, and thus were not in it.

        In any case, I'd be very interested to recieve the Y-DNA raw results from someone who did this test and see if I can include them in my file. This will allow to have a very precise comparison with Geno 2.0 results.

          Thanks Itai

          I have posted in a few places and will let you know if any results come in.

          greystones22 (R-M222) in post number 6 on here has ordered it

            Disappointing news. The Geno 2.0 test gave me a few rare SNPs for an R-L2 person. F3515, PF112, PF1610, PF4874 and PF4955. Only the first two are available through FTDNA to test so I wanted to confirm. My results came in negative.

            Right now it's confusing in my SNP list because the two SNPs are listed both as a positive and as a negative. The negative then is the true result. This gives me low confidence for my remaining rare SNPs.

            Very annoying I have to spend all this money to remove these erroneous SNPs from my list.

              Itai Perez posted a list of questionable SNPs on the GENEALOGY-DNA mailing list (see below). The GenoChip added a very large number of novel SNPs, and it often takes a lot of real-life data to sort out their status. That's where citizen science comes in. If you haven't already, you might consider uploading your data to Itai.

              I see F3515 was on Itai's list, but not PF112. I searched the RootsWeb mailing lists, and I see it's been discussed on the Haplogroup I list.

              [DNA] Questionable SNPs in Geno 2.0

              Hello,

              This was discussed on the ISOGG Facebook group, but not here, so on the advice of Ray Banks, I'll post it here in case people didn't see it.
              It seems that about a hundred SNPs show as positive in an erratic way across the haplogroups in the Geno 2.0 results. They show as positive in many people of different haplogroups, but not in other people of the same or similar haplogroups.

              This is the list of these SNPs: CTS1034+, CTS10436+, CTS10713+, CTS10738+, CTS11085+, CTS11454+, CTS11844+, CTS12173+, CTS2080+, CTS2223+, CTS230+, CTS2447+, CTS295+, CTS3234+, CTS335+, CTS3647+, CTS3763+, CTS3914+, CTS4276+, CTS4623+, CTS4714+, CTS477+, CTS5458+, CTS5580+, CTS6010+, CTS6353+, CTS6384+, CTS6891+, CTS7453+, CTS7492+, CTS7859+, CTS7951+, CTS8133+, CTS8178+, CTS8244+, CTS9096+, CTS947+, CTS9512+, CTS9548+, F1173+, F1221+, F1300+, F1327+, F1369+, F1707+, F1754+, F1831+, F1833+, F1842+, F1870+, F1882+, F2000+, F2137+, F2150+, F2177+, F2223+, F2494+, F2503+, F2546+, F2631+, F2845+, F2887+, F2932+, F3035+, F3039+, F317+, F3187+, F3225+, F3394+, F3397+, F3455+, F375+, F3948+, F3965+, F4131+, F4277+, F830+, F842+, F869+, F889+, F910+, F942+, F943+, F969+, L366+, L477+, L493+, L515+, L516+, L517+, L552+, L594+, M263+, PF4208+, PF4330+, PF5061+, PF6868+, PF7392+, Z148+, Z191+ and Z365+

              For instance, on their respective projects, these SNPs appear as positive for kit 78279 (D2a1b), 82291 (E-M78), N46362 (E-V22), 229706 (I1), N28466 (I2a2b), 199578 (O3a2c1) and they don't appear positive for kits 176409 (D2a1b), 52277(E-V12), 170291 (I1), N12526 (I2a2b) and 187595 (O1a).

              So if you encounter them on your projects, be aware that these SNPs are not to be trusted.

              If people are interested, here's a link to a file where I compared 70 people from diverse haplogroups. These problematic SNPs and the people who are positive to them appear highlighted in orange: https://www.dropbox.com/s/4b3zqcvxr4...no%202%200.xls

              Sincerely,

              Itaï Perez.

                Itai and the U152 project both made notes or grouping changes based upon my geno 2.0 raw results. I'm hoping Itai will see this and make appropriate changes. I e-mailed the project leader.

                  Z193 is another SNP that is unreliable due to it being heterozygous on Geno

                  An earlier (U152*) Z193- result recently showed as positive on Full Genome data. Not mine though, I don't have $1,250 to order it
