I found this on eupedia and found it interesting, since both U106 and U152 came from the Alps.
Here it is:
A U152* from FTDNA has been given a U106* result at 23andMe!
I hope the new V.3 hasn't awakened something!
I have questioned this result and await their response.
I have also sent the raw data to those in the know for analysis.
U106 and U152 are no more closely related than 3-5 thousand years ago. U152 definitely is of higher frequency in the Alpine area.
U106 has much higher frequencies further north, towards the North and Baltic Seas. Perhaps U106 did come from the Alpine region. We don't know.
However, the strange reports from the two different testing companies means there is a testing error. That's about all it probably means.
