We consider how, for quasidegenerate neutrinos with tribimaximal mixing at a high-energy scale, the mixing angles are affected by radiative running from high- to low-energy scales in a supersymmetric theory. The limits on the high-energy scale that follow from consistency with the observed mixing are determined. We construct a model in which a non-Abelian discrete family symmetry leads to both a quasidegenerate neutrino-mass spectrum and to near tribimaximal mixing.
