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.

NCBI's Gene resources include collections of curated nucleotide sequences used as references, sequence clusters to predict and study homologs, and various databases and tools for the study of gene expression.

Mar 17, 2025 · The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families.

Querying by gene symbol or NCBI-based nucleotide or protein ID generates a list of gene orthologues, alongside each being a corresponding orthologous protein (all based on RefSeq entries), with a graphical representation of conserved domains.

NCBI Gene and SNP Tutorial: Learn how to navigate the NCBI Gene and SNP databases to investigate specific genes, such as finding information on pathogenic alleles that cause genetic diseases.

The National Center for Biotechnology Information's (NCBI) Gene database (www.ncbi.nlm.nih.gov/gene) integrates gene-specific information from multiple data sources. NCBI Reference Sequence (RefSeq) genomes for viruses, prokaryotes and eukaryotes are the primary foundation for Gene records in that t …
