Box 3: Some filters in Gene

The Entrez system uses the term filters to connote the function that subsets a query or retrieval set by attributes of the record. Here are some common filters available from Gene. This is a report you can generate by selecting “Filters” from the blue sidebar within 'My NCBI'. The display from the preview/index menu is more concise.

You may select these commonly requested filters or use Browse to see all filters for this database.

Commonly Requested Filters

Gene records annotated on partial or complete chromosomal RefSeqs (Genes Genomes). Gene records with explicit links to RefSeq chromosome or contig accessions.

Gene records associated with citations in PubMed (gene pubmed). Gene records with explicit links to Entrez PubMed. Useful to identify genes that have associated publications.

Gene records associated with expression data in UniGene (gene unigene). Gene records with explicit links to Entrez UniGene. Calculated from common mRNA sequence data.

Gene records associated with PCR-based markers in UniSTS (gene unists). Gene records associated with PCR-based marker data in Entrez UniSTS. Associations are calculated by e-PCR or curated submissions.

Gene records associated with protein sequence (gene protein). Gene records with explicit links to Entrez Protein. Includes links to GenPept, RefSeq, and SwissProt accessions.

Gene records associated with variation information in dbSNP (gene snp). Gene records with explicit links to Entrez dbSNP. Supports finding genes with variation information available in dbSNP.

Gene records shown in Map Viewer (gene mapview). Gene records known to be on a current annotation of a genome.

Gene records with expression data in GEO (gene geo). Gene records with additional data in Gene Expression Omnibus (GEO), based on common sequence information.

Gene records with Gene Genotype reports in dbSNP(gene genotype). Gene records with reports of genotypes in the dbSNP database.

Gene records with homology data (gene homologene). Gene records with explicit links to Entrez HomoloGene. Useful to find genes that appear to be conserved.

Gene records with MIM (Mendelian Inheritance in Man) numbers (gene omim). Gene records with explicit links to OMIM. Includes links to both disease and “gene” records.

Gene records with nucleotide sequence data (gene nucleotide). Gene records with explicit links to Entrez nucleotide, excluding RefSeq chromosome or contig accessions. Useful to find genes that have nucleotide sequence information.

Gene records with proteins calculated to contain conserved domains (gene cdd). Gene records with RefSeq proteins calculated to contain conserved domains by comparison to the CDD database.
