We consider a modi?cation of tribimaximal (TBM) mixing matrix which accommodates non-
zero mixing angle ?13 and CP violation. We show that such a modi?cation of TBM mixing can be
achieved in a minimal seesaw model with discrete symmetry S4. This model is very predictive and
the undetermined parameters are either mass of heavy neutrinos and a Majorana phase. Possible
values of the Dirac-type CP phase ?D can be predicted with regards to two neutrino mixing angles
in the standard parametrization of the neutrino mixing matrix. The unknown parameters are
constrained through leptogenesis by imposing the recent experimental neutrino data.
