Haplogroup R-Z18
R-Z18 is a
Description
Z18, also called S493, is defined to be mutation in which the nucleotide at position 14,991,735[1] along the Y chromosome that has mutated from guanine (G) to adenine (A). R-U106 is one of the major sub groups of R1b in coastal Western Europe, but Z18 only makes up about 5-10% of R-U106.
Discovery
Z18 was discovered during Phase 3 of the 1000 Genomes Project[2] and entered on 16 August 2014 into the SNP database dbSNP at the National Center for Biotechnology Information as reference SNP cluster report rs767290651.[3]
Distribution
R-Z18 has its highest concentrations in Scandinavia, but is also found throughout areas of Germanic migration, including the Low Countries, Central Europe, and the British Isles.[4] The likely Scandinavian origins of R-Z18 are bolstered by the dominance of Scandinavian individuals among ancient DNA samples. These consist of individuals found in Sweden, Norway, and Iceland; settlers in Orkney and the Isle of Man; executed Scandinavians found in Oxfordshire and Dorset; and a Lombard individual found in what is now Hungary.[5][6][7][8]
On the basis of genetic results, the first carrier of this mutation lived around 2200 B.C., with a 90% confidence range of 3000 B.C. to 1400 B.C.[9]
Subclades
Major known subclades of R-Z18 include R-ZP156, R-S11601, R-DF95, R-FGC7637, R-Z2396, R-S6119 and R-Z17.[10] Although they continue to increase as more are found.
