Neutrino mass sum rules are a common class of predictions in flavour models relating the Majorana phases to the neutrino masses. This leads, for instance, to strong restrictions on the effective mass probed in experiments on neutrinoless double beta decay. We will discuss generic corrections to these neutrino mass sum rules which arise for example from renormalization group evolution and present the effect of the corrections on the predictions from all sum rules found in the literature. Most of the predictions are rather robust under renormalization group effects, for example the lower bound on the lightest neutrino mass does not change significantly.
