Realistic neutrino mixing is achieved at a one-loop level radiatively using S3×Z2 symmetry. The model is comprised of two right-handed neutrinos, maximally mixed to produce the structure of the left-handed Majorana neutrino mass matrix characterized by θ13=0, θ23=π/4, and any value of θ120 particular to the tribimaximal (TBM), bimaximal (BM) and golden ratio (GR) or other mixings. A small deviation from this maximal mixing between the two right-handed neutrinos could generate nonzero θ13, shifts of the atmospheric mixing angle θ23 from π/4, and also could correct the solar mixing angle θ12 by a small amount altogether in a single step. In this scotogenic mechanism of generating a nonzero θ13 by shifting from the maximal mixing in the right-handed neutrino sector, two Z2 odd inert scalar SU(2)L doublets were used, the lightest of which can serve as a dark matter candidate.
