In grand unified theories the flavor mixing angles of leptons are related to those of quarks. In this paper we study SO(10) theories with a precise group-theoretic relation at the GUT scale for mixing between the heaviest two generations: [theta][sub [mu][tau]][sup 0]=[kappa][vert bar][ital V][sub [ital c][ital b]][sup 0][vert bar]. A comprehensive operator search yields all possible cases where [kappa] is a group theory Clebsch coefficient. The resulting predictions for [nu][sub [mu]][nu][sub [tau]] oscillations are scaled from the grand to the weak scales. We find that all but one of the models which have such a relationship between [theta][sub [mu][tau]][sup 0] and [ital V][sub [ital c][ital b]][sup 0], and are not already excluded, will be probed by the CHORUS and NOMAD experiments. A more precise mixing measurement, for example, by the proposed P803 experiment, could distinguish between the models.
