A deletion here and there may be pretty common, but multiple deletions of a whole section is not.
I have results of 14 individuals who have multiple deletions in the same locations! The lab used was FTDNA. The resulting multiple deletions have been helpful markers to identify a common ancestor or a connection to families with different surnames. We are having success in identifying NPEs because of the uniqueness of our results.
I understand the reluctance to accept these results as accurate. Fathers and sons have take the Y-DNA test at different times with identical results.
I believe the results deserve to be taken seriously, without suspicion, maybes and could be if.....
Multiple Deletions are very rare, but they are real! It is time for serious consideration be given to the benefits of these results.
The locations between 6,868,881 and 8,851,357, in build 37, returned zero results.
