We present an extension of the Standard Model (SM) based on the discrete flavor symmetry S 3 which gives a neutrino mass matrix with two-zero texture of Fritzsch-type and nearly diagonal charged lepton mass matrix. The model is compatible with the normal hierarchy only and predicts sin 2 θ 13 ≈ 0.01 at the best fit values of solar and atmospheric parameters and maximal leptonic CP violation.
