  In light of the latest neutrino oscillation data, we examine whether the
leptonic flavor mixing matrix can take on an exact form of tri-bimaximal (TBM),
golden-ratio (GR) or bimaximal (BM) mixing pattern at a superhigh-energy scale,
where such a mixing pattern could be realized by a flavor symmetry, and become
compatible with experimental data at the low-energy scale. Within the framework
of the Minimal Supersymmetric Standard Model (MSSM), the only hope for
realizing such a possibility is to count on the corrections from the
renomalization-group (RG) running. In this work we focus on these radiative
corrections, and fully explore the allowed parameter space for each of these
mixing patterns. We find that when the upper bound on the sum of neutrino
masses $\Sigma^{}_\nu \equiv m^{}_1 + m^{}_2 + m^{}_3 < 0.23~\text{eV}$ at the
$95\%$ confidence level from Planck 2015 is taken into account, none of these
mixing patterns can be identified as the leptonic mixing matrix below the
seesaw threshold. If this cosmological upper bound on the sum of neutrino
masses were relaxed, the TBM and GR mixing patterns would still be compatible
with the latest neutrino oscillation data at the $3\sigma$ level, but not at
the $1\sigma$ level. Even in this case, no such a possibility exists for the BM
mixing.
