  1. The cardiac septal defect sub-network was created using known cardiac septal defect genes (from OMIM) and their immediate interactants, and was prioritized using functional annotation and PPIN based methods. Functional annotation based prioritization was done using ToppGene server. The PPIN based rankings were obtained using 3 methods: K step Markov, Hits with Priors, and PageRank with Priors. The highlighted genes are those occurring in all of the prioritized top 20 genes generated using different methodologies. Note that the Hits with Priors and PageRank with Priors gave identical results (see Additional Files 3, 4 and 5 for the list of genes and prioritization results). The genes marked with * are associated with abnormal heart morphology (ToppGene: 15/20; K-Step Markov: 14/20; and Hits with Priors and PageRank with Priors: 13/20) while those marked with # have been reported to be associated with cardiac septal defects (6/20 and 3/20 in ToppGene and PPIN prioritized top 20 candidate genes for cardiac septal defects).
