The HUGO Gene Nomenclature Committee (HGNC) aims to assign a unique and ideally meaningful name and symbol to every human gene. The HGNC database currently comprises over 24 000 public records containing approved human gene nomenclature and associated gene information. Following our recent relocation to the European Bioinformatics Institute our homepage can now be found at http://www.genenames.org, with direct links to the searchable HGNC database and other related database resources, such as the HCOP orthology search tool and manually curated gene family webpages.
