Tim,
Please be aware of an earlier post by John Chandler that some of the 68-78 markers were incorrectly transposed by Leo Little from
the SMGF 2004 poster.
These are the corrected figures for the 4 markers in question.
Ref:- http://www.smgf.org/resources/papers/ASHG2004-4.pdf
444 medium 0.00296
445 slow 0.00095
446 medium 0.00314
452 medium 0.00174

Note:- while the values may have changed, only 445 has changed type from medium to slow

Cheers
Dennis W

Dear Bryan,
I don't recall that anyone on the list has ever tried to define the
breakpoints between slow, medium, and fast mutating markers before. As
others have mentioned, this is an arbitrary decision. I sorted the 67
markers in the FTDNA 67 marker panel as well as 9 markers included in the
SMGF 43 marker panel that aren't included in the FTDNA 67 marker panel by
their mutation rates as found on Leo Little's web site at
http://freepages.genealogy.rootsweb.ancestry.com/~geneticgenealogy/ratestuff
.htm. The mutation rates were calculated by John Chandler. These rates are
probably among the most accurate mutation rates that have been published to
date. I arbitrarily chose a mutation rate of 0.001 as the breakpoint
between slow and medium mutating markers. I arbitrarily chose a mutation
rate of 0.005 as the breakpoint between medium and fast mutating markers. I
hope you find this list of help to you. Feel free to chose different
breakpoints if you prefer.
Sincerely,
Tim Janzen

This is probably a naive question , but what are generally considered to be
the "break-points" in a classification of slow, medium and fast mutating
STR's. Thanks, Bryan Cook
