Looking over the Francalacci data on Sardinia, it looks like there are ten M269(xL23). All ten have the following either observed or inferred:

23047845 G>A (10 of 10)
15256141 G>A
21110969 A>G
14579448 G>T
17903480 C>T
22871037 T>C
21631153 C>A
22593933 G>A
19369222 A>T

So this means that all M269* Sardinians in the dataset form a single brother clade to L23 and not a diverse mix of M269 types. All six L23(xL11) samples are Z2103/Z2105+ and all three L51(xL11) samples are all Z2115+.

Very interesting. Thank you, Richard.

Even though they are a brother clade, identifying brothers to L23+ folks is very important.

Should we consider it an important clue that among R1b in Europe, the Basques and Sardinians stand-alone at the bottom of Dienekes' West Asian autosomal content?

We haven't found any M269xL23 among the Basques, have we?

I don't know of any Basque M269(xL23) in any study or database. As a whole, it looks like M269(xL23) is completely absent in Iberia and there is only a trickle of L23(xZ2103/Z2105).

I don't pay any attention to Dienekes' West Asian autosomal groupings as they have no correlation to a single Y-lineage.

Do we have any decent Y STR coverage for Sardinian R1b DNA? Do we have DYS437, DYS448 and/or GataH4? It would be interesting if we found some North-South cluster folks. I'm assuming the data you are looking at doesn't cover DF27 for those that are L51/L11/P312, or does it?

What does this mean for PF7558, PF7562, and PF7563? Are these Sardinian M269(xL23) negative for these three Sardinian SNPs? These are the SNPs found in the L23- L150+ group of the ht35 project. As Rathna has pointed out on another forum, FTDNA kit 282121 in the O'Donnell Surname Project is also L23- L150+ PF7558+, PF7562+, and PF7563+.

PF7558, PF7562, and PF7563 are all labeled as "Approx. hg: R-M269" and "Extracted from genome study of Sardinian samples" by Thomas Krahn.

Build 36:
PF7558 = chrY:3489974-3489974
PF7562 = chrY:8012440-8012440
PF7563 = chrY:8670246-8670246

Build 37
PF7558 = chrY:3429974-3429974
PF7562 = chrY:7952440-7952440
PF7563 = chrY:8610246-8610246

None of these are in the Sardinia supplementary material, but I was told that these samples were re-sequenced to cover a larger area after this study, so it may be that for this paper, these areas were not covered. Either that or they come from additional Sardinian samples.

Actually I found a Basque R-M269* and I spoke about it either with Maju or with JeanL, but don't ask me where and when.

Truly have you found these L23(xZ2103/Z2105)?

Sorry, I mean to write that there is only a trickle of L23(xL51) in Iberia and therefore very little potential for Z2103/Z2105 or true L23(xL51,xZ2103/Z2105) in Iberia.

Is it possible to do meaningful variance calculations on them?

Alan, they only provided SNPs, no STRs, so variance is not possible.

ah OK. Didnt realise that.

I cannot recall if I have seen a distribution map for M269* ever made? Even if its relatively young today its still interesting as a branch off before L23.
