Has anyone else heard of this marker & does anyone know if Family Tree DNA already tests for these? I got the following e-mail today:
"EthnoAncestry is pleased to announce the release of a potentially exciting new Y chromosome SNP marker, S144, which has been observed in the S28+ subgroup of R1b. The marker was identified through comparison of genome-wide scan data, and appears to be downstream of S139, however we don't yet know how common or rare it is.
EthnoAncestry also offer two further newly identified markers within S28, the above S139 and also M228. S139 distinguishes ~85% of S28 who are positive at this marker, from ~15% who are negative. The negative (ancestral) group appear to be more common in Germany and Italy than elsewhere, but have been seen from Spain to Eastern Europe. M228 was recently shown to have occurred independently in the S28+S139+ group. This may be a family SNP, but only further individuals testing the marker will clarify this.
The relationship between these groups is illustrated in the attached tree. Testing these SNP will advance your knowledge of the sublineage you belong to while helping to unravel the prehistory of Europe."
