That's not a problem for Ballantyne et al.'s mutation rate estimates

http://download.cell.com/AJHG/mmcs/journals/0002-9297/PIIS0002929710004192.mmc1.pdf

as they do not use the most likely value as the point estimate of the
marker mutation rate, but rather the median of the posterior
distribution, i.e., it is 50% probable for the mutation's rate to be
higher and 50% lower than the point estimate.
