OOPS. Here is the correct URL. Sorry.
I have a well documented parallel mutation in my Kerchner surname
project. It was at DYS449.

Whether the documentation was wrong or not is always hard to know in someone else's family. However, there have been enough reported that everyone should be alert to them.
