Haplogroup G-M406

In human genetics, Haplogroup G-M406 is a Y-chromosome haplogroup. G-M406 is a branch of Haplogroup G Y-DNA (M201). More specifically in descending order, G-M406 is a subbranch also of G2 (P287), G2a (P15) and finally G2a2b (L30/S126) Haplogroup G-M406 seems most common in Turkey and Greece. Secondary concentrations of G-M406 are found in the northern and eastern Mediterranean, and it is found in very small numbers in more inland areas of Europe, the Middle East, and the southern Caucasus Mountains area.

A large number of G-M406 persons have the value of 21 at short tandem repeat (STR) marker DYS390, and all G-M406 men will have the M406 SNP mutation which characterizes this group. The 21 at DYS390 is uncommon among G persons outside the G-M406 group. In G-M406 persons, the DYS391 marker has mostly a value of 10, but sometimes 11, and DYS392 is almost always 11 except in one distinct cluster. If a sample meets the criteria indicated for these three markers, it is likely the sample is G-M406. This M406 SNP was first reported in 2008. The M designation indicates it was first identified at Stanford University. M406 is located on the Y chromosome at position 2809995, reference SNP ID i4000120. The mutation involves a change from T to G.
