Entrez Gene is a gene-specific database at the National Center for Biotechnology Information (NCBI), providing unique, stable identifiers for genes and other loci from a variety of genomes. The database integrates curated data from NCBI's Reference Sequence project (RefSeq), collaborating model organism databases, and other NCBI databases. It offers interactive browsing, LinkOut, and bulk transfer via FTP. Key features include nomenclature, sequence localization, gene products, associated markers, phenotypes, and links to external databases. Entrez Gene supports multiple views and reports, including gene tables and summary displays, and can be accessed through various NCBI tools and interfaces. The database aims to provide comprehensive and integrated gene information for public use, with continuous updates and improvements.Entrez Gene is a gene-specific database at the National Center for Biotechnology Information (NCBI), providing unique, stable identifiers for genes and other loci from a variety of genomes.
