W5 is defined by two coding region mutations - 06528 and 15775.
Therefore basic W5's are indistinguishable from W1's and W3's in HVR1
and from W3's in HVR1 and HVR2.
However the major subgroup W5a is defined by the HVR1 mutation 16362 (and the coding region mutation 10097) and therefore W5a's can be identified by HVR1 results alone (with caution, since 16362 appears in other W subgroups, but in combination with other HVR1 results).
19% of W's are of this subgroup. It is the youngest major group, and a uniquely European group, originating only 5500 years ago. Its distribution corresponds to the expansion of Celtic, and then Germanic tribes into Europe.
W5 has its highest concentrations in Hungary, Germany, Ireland, the UK, and Switzerland.
