HGNC is responsible for approving unique symbols and names for human loci, including protein coding genes, ncRNA genes and pseudogenes, to allow unambiguous scientific communication. is a curated online repository of HGNC-approved gene nomenclature, gene families and associated resources including links to genomic, proteomic and phenotypic information.

Search our catalogue of more than 39,000 symbol reports using our improved search engine (see Search help), search lists of symbols using our Multi-symbol checker and identify possible orthologs using our HCOP tool.

Download our ready-made data files from our Statistics and Downloads page, create your own datasets using our Custom Downloads tool or write a script/program utilising our REST service.

Submit your gene symbol and name proposals to us to be accredited with HGNC approved nomenclature for use in publications, databases and presentations.

  • We are proposing simplifying our "Custom Downloads" tool by bringing the data provided in line with that displayed in our symbol reports. Currently users can download two separate fields for some IDs: "HGNC curated" and "mapped data". This has caused some confusion as in our symbol reports HGNC curated data are displayed in preference, and mapped data are only shown if there is no HGNC curated ID i.e. only one ID is shown per symbol. Please use our feedback form to comment and let us know if this update may cause you any problems.

  • Our new gene family pages and a new more powerful search has been released. Our gene family improvements include a searchable gene family index, browse through and download gene family hierarchies, and a numerical ID for each gene family. Our new search now allows the user to search everything with one request including our new family data making searching easier.
