We perform a complete global phenomenological analysis of a realistic string-inspired model based on the supersymmetric Pati-Salam SU(4)× SU(2)L × SU(2)R gauge group supplemented by a U(1) family symmetry, and present predictions for all observables including muon g-2, τ→ μγ, and the CHOOZ angle. Our analysis demonstrates the compatibility of such a model with all laboratory data including charged fermion masses and mixing angles, LMA MSW and atmospheric neutrino masses and mixing angles, and b → s γ, allowing for small deviations from third family Yukawa unification. We show that in such models the squark and slepton masses may be rather light compared to similar models with exact Yukawa unification.
