WhichGenes is a bioinformatics gene set building tool. It allows the user to create and manage custom genesets extracted from several sources. Currently, WhichGenes can extract genes from:

• GeneCards Disease Genes. Uses Gene Cards disease genes query to retrive a gene list
• Gene Ontology. Genes annotated whith a GO (via AmiGO)
• KEGG Pathway. Genes involved in KEGG Pathways
• Biocarta Pathway. Genes involved in Biocarta Pathways
• Reactome Pathway. Genes involved in Reactome Pathways
• MSigDB Positional GeneSets. GeneSets of the MSigDB's C1 Collection (GSEA)
• TargetScan microRNA targets. Uses TargetScan to retrieve genes which are microRNA targets
• Ensembl genes in bands. Uses Ensembl to provide genes in given locations or ranges
• miRBase Targets. Uses miRBase Targets version 5 to retrieve genes as target of microRNAs
• Chemical CTD. Chemical Interacting genes
• Diseases CTD. Genes related with diseases via CTD
• CancerGenes. Genes in Large-scale Sequencing Cancer Genome Projects via CancerGenes
• IntAct interacting genes. Uses IntAct to get genes whose proteins interact with the protein of a given gene(s)
• Sanger Decipher. Genes related to syndromes in Sanger's Decipher DB

• KEGG Pathway. Genes involved in KEGG Pathways
• Biocarta Pathway. Genes involved in Biocarta Pathways
• Reactome Pathway. Genes involved in Reactome Pathways
• Ensembl genes in bands. Uses Ensembl to provide genes in given locations or ranges
• miRBase Targets. Uses miRBase Targets version 5 to retrieve genes as target of microRNAs
• Chemical CTD. Chemical Interacting genes
• Diseases CTD. Genes related with diseases via CTD
