The conventional gene set enrichment analysis often fails to reveal associations between disease phenotypes and the gene sets with a short list of poorly annotated genes, because the existing annotations of disease-causative genes are incomplete. This article introduces a network-based computational approach called rcNet to discover the associations between gene sets and disease phenotypes. A learning framework is proposed to maximize the coherence between the predicted phenotype\u2013gene set relations and the known disease phenotype-gene associations. An efficient algorithm coupling ridge regression with label propagation and two variants are designed to find the optimal solution to the objective functions of the learning framework.<\/jats:p><jats:p>Results: We evaluated the rcNet algorithms with leave-one-out cross-validation on Online Mendelian Inheritance in Man (OMIM) data and an independent test set of recently discovered disease\u2013gene associations. In the experiments, the rcNet algorithms achieved best overall rankings compared with the baselines. To further validate the reproducibility of the performance, we applied the algorithms to identify the target diseases of novel candidate disease genes obtained from recent studies of Genome-Wide Association Study (GWAS), DNA copy number variation analysis and gene expression profiling. The algorithms ranked the target disease of the candidate genes at the top of the rank list in many cases across all the three case studies.<\/jats:p><jats:p>Availability: \u00a0http:\/\/compbio.cs.umn.edu\/dgsa_rcNet<\/jats:p><jats:p>Contact: \u00a0kuang@cs.umn.edu<\/jats:p>","DOI":"10.1093\/bioinformatics\/btr463","type":"journal-article","created":{"date-parts":[[2011,8,9]],"date-time":"2011-08-09T04:59:10Z","timestamp":1312865950000},"page":"2692-2699","source":"Crossref","is-referenced-by-count":30,"title":["Inferring disease and gene set associations with rank coherence in networks"],"prefix":"10.1093","volume":"27","author":[{"given":"TaeHyun","family":"Hwang","sequence":"first","affiliation":[{"name":"1 Department of Computer Science and Engineering, University of Minnesota Twin Cities, Minneapolis, MN 55455, USA, 2College of Software, Nankai University, Tianjin, China and 3Department of Bioinformatics and Computational Biology, Genentech Inc., South San Francisco, CA 94080, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Zhang","sequence":"additional","affiliation":[{"name":"1 Department of Computer Science and Engineering, University of Minnesota Twin Cities, Minneapolis, MN 55455, USA, 2College of Software, Nankai University, Tianjin, China and 3Department of Bioinformatics and Computational Biology, Genentech Inc., South San Francisco, CA 94080, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maoqiang","family":"Xie","sequence":"additional","affiliation":[{"name":"1 Department of Computer Science and Engineering, University of Minnesota Twin Cities, Minneapolis, MN 55455, USA, 2College of Software, Nankai University, Tianjin, China and 3Department of Bioinformatics and Computational Biology, Genentech Inc., South San Francisco, CA 94080, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinfeng","family":"Liu","sequence":"additional","affiliation":[{"name":"1 Department of Computer Science and Engineering, University of Minnesota Twin Cities, Minneapolis, MN 55455, USA, 2College of Software, Nankai University, Tianjin, China and 3Department of Bioinformatics and Computational Biology, Genentech Inc., South San Francisco, CA 94080, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rui","family":"Kuang","sequence":"additional","affiliation":[{"name":"1 Department of Computer Science and Engineering, University of Minnesota Twin Cities, Minneapolis, MN 55455, USA, 2College of Software, Nankai University, Tianjin, China and 3Department of Bioinformatics and Computational Biology, Genentech Inc., South San Francisco, CA 94080, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2011,8,8]]},"reference":[{"key":"2023012512002924500_B1","doi-asserted-by":"crossref","first-page":"596","DOI":"10.1016\/j.coi.2009.09.014","article-title":"The genetics of autoimmune diseases: a networked perspective","volume":"21","author":"Baranzini","year":"2009","journal-title":"Curr.
