dbGAP is a manually curated catalog of experimentally validated genes that are assumed to be associated with the psoriasis. Each entry contains information regarding the gene and protein sequences, its location, chromosomal positions, accession numbers, gene ontology and homology with other eukaryotic genomes, protein information like structure details, visualization, protein-protein interactions etc. The database has major focus on the details of the genetic variations of the disease causing genes like SNPs, functional consequence, populations studied, p-values and Odds ratios for gene's assoiations with disease. The database has cross reference to other web resources like NCBI, OMIM, HGNC, Ensembl, HPRD, PharmGKB, KEGG, VEGA, UniProtKB, PDB etc.
