A class of predictive SO(10) grand unified theories with highly asymmetric mass matrices, known as lopsided textures, which was developed to accommodate the observed mixing in the neutrino sector, can effectively determine the rate for charged lepton flavor violation (LFV), and in particular the branching ratio for \stackrel\ensuremath→\ensuremathμe\ensuremathγ. Assuming that the supersymmetric GUT breaks directly to the constrained minimal supersymmetric standard model (CMSSM), we find that in light of the combined constraints on the CMSSM parameters from direct searches and from the WMAP satellite observations, the resulting predicted rate for \stackrel\ensuremath→\ensuremathμe\ensuremathγ in this model class can be within the current experimental bounds for low tan\ensuremathβ, but that the next generation of \stackrel\ensuremath→\ensuremathμe\ensuremathγ experiments would effectively rule out this model class if LFV is not detected.
