Unrestricted Access


Gene integrates information from a wide range of species. A record may include nomenclature, Reference Sequences (RefSeqs), maps, pathways, variations, phenotypes, and links to genome-, phenotype-, and locus-specific resources worldwide.


All NCBI databases and databanks, as wells as items on the NCBI Bookshelf, are covered in the NCBI Helf Manual.  A link is located in the footer at the bottom of each page or directly at 

User tools and features

Gene is accessed like any other Entrez database, namely by

  • querying on any word,
  • restricting the query term to a certain field, or
  • applying filters or properties

Users may perform the following types of searches (examples are provided at the bottom of the Gene home page): free text, chromosome & symbol, partial name & multiple species, associate sequence accession, gene name (symbol), publication (PubMed ID), gene ontology terms or identifiers, genes with short variants of medical interest, chromosome & species, and Enzyme Commission (EC) number.

Here are some representative queries:
