  We present a class of supersymmetric (SUSY) GUT models that can explain the
apparent discrepancy between the SM predictions and experimental values of muon
g-2 while providing testable signals for lepton flavor violation in charged
lepton decays. Moreover, these models predict LSP neutralino abundance that is
compatible with the Planck dark matter bounds. We find that scenarios in the
framework of $SU(4)_c\times SU(2)_L\times SU(2)_R$ unification, with additional
symmetries to explain fermion masses and neutrino oscillations, provide
interesting benchmarks for the search of SUSY by correlating a possible
manifestation of it in dark matter, rare lepton decays and LHC signals.
