NCBI Gene

The Gene database provides detailed information for known and predicted genes defined by nucleotide sequence or map position. Gene supplies gene-specific connections in the nexus of map, sequence, expression, structure, function, citation, and homology data. Unique identifiers are assigned to genes with defining sequences, genes with known map positions, and genes inferred from phenotypic information. These gene identifiers are used throughout NCBI's databases and tracked through updates of annotation. Gene includes genomes represented by NCBI Reference Sequences (or RefSeqs) and is integrated for indexing and query and retrieval from NCBI's Entrez and E-Utilities systems.

该基因数据库为已知及预测基因提供详尽的资料，这些基因通过核苷酸序列或图谱位置进行定义。基因数据库在图谱、序列、表达、结构、功能、引用和同源性数据之间构建了针对特定基因的关联网络。对于具有定义序列的基因、已知图谱位置的基因以及从表型信息推断出的基因，均分配了唯一的标识符。这些基因标识符在NCBI的数据库中得到广泛应用，并通过注释更新的途径进行追踪。数据库包含由NCBI参考序列（或RefSeqs）所代表的基因组，并集成于NCBI的Entrez和E-Utilities系统，以实现索引、查询和检索功能。
