What you say might have made sense if not for the fact that countless other Jewish students were similarly denied from MGU. Did they all have uncles that lived in the West? In Frenkel's story, the lady from the correspondence school hears his name and that he wants to apply to MGU, and immediately asks for his nationality. When he replies "Russian", she keeps asking until he replies that his father is Jewish. Then she flat-out says, "Do you know that Jews are not accepted to Moscow University?". I think it is fairly clearly established that this is the reason he was denied a place there.
