Oleg Balanovsky has just announced that he discovered a new branch of L23 - GG400, a "brother" of L51 and Z2103.
Up to this point, we used to divide all of R1b-L23+ into just two major branches (Western defined by L51 and Eastern defined by Z2103), while all lineages positive for L23 but negative for both L51 and Z2103 mutations, used to be classified as basal or unresolved L23*. It turns out, that at least some part of this basal or until now unresolved L23* can be classified as belonging to a newly discovered branch defined by SNP called GG400. From now on, we will have not just two, but three main branches of L23+, namely: L23>L51, L23>Z2103 and L23>GG400. It seems, that this GG400 branch is concentrated mainly in Eastern Europe and probably a large part of basal or unresolved L23* samples (negative for L51 and Z2103) from FTDNA Polish Project will turn out to be under L23>GG400.
In total few (four or five) percent of ethnic Poles are either L23>Z2103, L23>GG400 or other L23* negative for L51.
Another typically Eastern European branch of Non-L51 is L23>Z2103>Y5587 ("EE Type" in FTDNA Polish Project).

According to this information, ancient L23* from Yamnaya that was negative for Z2103, was most likely GG400.
