We discuss results on neutrino mixing in a three family scenario. We use the Røp MSSM for the theoretical description of the neutrino masses. We show that one has to include the tree-level and the qq̃ one-loop as well as the ll̃ one-loop contribution to the neutrino mass matrix to get three massive neutrinos. By introducing an additional U(1) flavor symmetry which has been successful in explaining the mass hierarchy of quarks and leptons, we are able to correlate many parameters of our model. Confronting the experimental and theoretical results for the neutrino mass matrices, we find a unique scenario for the neutrino masses and the couplings relevant for the neutrino mixing.
