Orphanet (website): The portal for rare diseases and orphan drugs.
OMIM (website): Online Mendelian Inheritance in Man is a comprehensive, authoritative, and timely compendium of human genes and genetic phenotypes.
HPRD (website): The Human Protein Reference Database represents a centralized platform to visually depict and integrate information pertaining to domain architecture, post-translational modifications, interaction networks and disease association for each protein in the human proteome. All the information in HPRD has been manually extracted from the literature by expert biologists who read, interpret and analyze the published data.
UniProt (website): Comprehensive, high-quality and freely accessible resource of protein sequence and functional information.
ToppGene Suite (website): ToppGene Suite is a one-stop portal for (a) gene list functional enrichment, (b) candidate gene prioritization using either functional annotations or network analysis or both, and (c) identification and prioritization of novel disease candidate genes in the interactome.
ToppCluster (website): ToppCluster is a tool for performing multi-cluster gene functional enrichment analyses on large scale data (microarray experiments with many time-points, cell-types, tissue-types, etc.). ToppCluster facilitates co-analysis of multiple gene lists and yields as output a rich functional map showing the shared and list-specific functional features.
Gephi (website): Gephi is an open graph viz platform that facilitates interactive visualization and exploration for all kinds of networks and complex systems, dynamic and hierarchical graphs.
GexfWalker (website): GexfWalker is a light Flash web application to visualize and explore graphs.
SeaDragon (website): Zoom.it (formerly Seadragon) is a free service for viewing and sharing high-resolution imagery.
