We are interested in exploiting domain knowledge for the task of candidate gene prioritization. In this paper, we present a new gene prioritization method that learns a probabilistic knowledge model and exploits it to prioritize candidate genes. The knowledge model is represented by a network of associations among domain concepts (e.g., genes) and is extracted from a domain database (e.g., protein-protein interaction database). This knowledge model is then used to perform probabilistic
