  We study a class of models for tri-bimaximal neutrino mixing in SO(10) grand
unified SUSY framework. Neutrino masses arise from both type-I and type-II
seesaw mechanisms. We use dimension five operators in order to not spoil
tri-bimaximal mixing by means of type-I contribution in the neutrino sector. We
show that it is possible to fit all fermion masses and mixings including also
the recent T2K result as deviation from the tri-bimaximal.
