BACKGROUND: Finding gene-disease and disease-disease associations play important
roles in the biomedical area and many prioritization methods have been proposed
for this goal. Among them, approaches based on a heterogeneous network of genes
and diseases are considered state-of-the-art ones, which achieve high prediction
performance and can be used for diseases with/without known molecular basis.
RESULTS: Here, we developed a Cytoscape app, namely HGPEC, based on a random walk
with restart algorithm on a heterogeneous network of genes and diseases. This app
can prioritize candidate genes and diseases by employing a heterogeneous network
consisting of a network of genes/proteins and a phenotypic disease similarity
network. Based on the rankings, novel disease-gene and disease-disease
associations can be identified. These associations can be supported with network-
and rank-based visualization as well as evidences and annotations from biomedical
data. A case study on prediction of novel breast cancer-associated genes and
diseases shows the abilities of HGPEC. In addition, we showed prominence in the
performance of HGPEC compared to other tools for prioritization of candidate
disease genes. CONCLUSIONS: Taken together, our app is expected to effectively
predict novel disease-gene and disease-disease associations and support network-
and rank-based visualization as well as biomedical evidences for such the
associations.
