Abstract
We reconsider quantum gravitational threshold corrections to the unification of fermion masses in grand unified theories. We show that the running of the Planck mass can have a sizable effect on these thresholds that are thus much more important than naively expected. These corrections make any extrapolation from low energy measurements challenging.
