  The supersymmetric (SUSY) minimal SO(10) model is a well-motivated grand
unified theory, where the Standard Model (SM) fermions have Yukawa couplings
with only one ${\bf 10}$-plet and one $\overline{\bf 126}$-plet Higgs fields
and it is highly non-trivial if the realistic quark and lepton mass matrices
can be reproduced in this context. It has been known that the best fit for all
the SM fermion mass matrices is achieved by a vacuum expectation value of the
$\overline{\bf 126}$-plet Higgs field being at the intermediate scale of around
${\cal O}(10^{13})$ GeV. Under the presence of the SO(10) symmetry breaking at
the intermediate scale, the successful SM gauge coupling unification is at risk
and likely to be spoiled. Recently, it has been shown that the low-energy
fermion mass matrices, except for the down-quark mass predicted to be too low,
are very well-fitted without the intermediate scale. In order to resolve the
too-low down quark mass while keeping the other fittings intact, we consider
SUSY threshold corrections to reproduce the right down quark mass. It turns out
that this requires flavor-dependent soft parameters. Motivated by this fact, we
calculate particle mass spectra at low energies with flavor-dependent sfermion
masses at the grand unification scale. We present a benchmark particle mass
spectrum which satisfies a variety of phenomenological constraints, in
particular, the observed SM-like Higgs boson mass of around 125 GeV and the
relic abundance of the neutralino dark matter as well as the experimental
result of the muon anomalous magnetic moment. In the resultant mass spectrum,
sleptons in the first and second generations, bino and winos are all light, and
this scenario can be tested at the LHC Run-2 in the near future.
