  • Gene Background

    Gene provides a unified query environment for genes defined by sequence and/or in NCBI's Map Viewer. You can query on names, symbols, accessions, publications, GO terms, chromosome numbers, E.C. numbers, and many other attributes associated with genes and the products they encode.

    Because Gene is now an Entrez database, all the familiar and useful functions are now available, including Preview/Index, History, and LinkOut.

    Please note: Entrez Gene is under active development. We welcome your suggestions. We have also added a choice in our Feedback/Corrections form for suggestions; both paths reach the same staff.

    Getting started Sample queries
    Look for genes by name part and multiple species transporter AND ("Drosophila melanogaster"[orgn] OR "Mus musculus"[orgn])    more...
    Look for genes by chromosome and symbol (II[chr] OR 2[chr]) AND adh*[sym]    more...
    Look for genes by sequence accession M11313    more...
    What's new?

    June-July, 2004 GeneRIF submissions are supported from Gene. A new page summarizing the status of the LocusLink->Gene transition is provided.

    There are now two types of links between Gene and dbSNP. The one called SNP has been provided from the beginning; it results in a listing of all the reference SNPs for a gene. The newer one, GeneView in dbSNP connects to the gene-based report of variation associated with a Gene. This report includes a graphical representation of the position of each variation, whether a variant affects a protein sequence, and tables of attributes of all the variants.

    March 24, 2004 An initial set of tab-delimited files became available for transfer by ftp. These include Gene/RefSeq and Gene/PubMed reports.

    December 15, 2003 Gene became accessible via the Entrez cross-database search mechanism. An ftp site is still under development.

    November 20, 2003 Gene became available in a limited mode. When more functions are implemented, Gene will be fully integrated with other Entrez databases, including global query.
