gene_info_fetch
Fetch comprehensive gene information from NCBI Gene database using gene symbols or IDs to access structured records including summaries, locations, and aliases.
Instructions
Fetch comprehensive gene information from NCBI Gene database.
This specialized wrapper provides easy access to gene records with structured output.
Args: gene_symbol: Gene symbol (e.g., "BRCA1", "TP53") gene_id: NCBI Gene ID (e.g., "672" for BRCA1) organism: Organism name (default: "Homo sapiens") use_cache: Whether to use cached results (default: True)
Returns: Dictionary containing: - gene_id: NCBI Gene ID - symbol: Official gene symbol - name: Full gene name - summary: Gene summary/description - organism: Organism name - chromosome: Chromosomal location - aliases: List of gene aliases - type: Gene type (protein-coding, ncRNA, etc.) - cached: Whether result was from cache (if use_cache=True)
Examples: >>> gene_info_fetch(gene_symbol="BRCA1") >>> gene_info_fetch(gene_id="672") >>> gene_info_fetch(gene_symbol="Brca1", organism="Mus musculus")
Notes: - Provide either gene_symbol or gene_id (gene_id takes precedence) - Organism filter helps disambiguate gene symbols - Rate limited (3 req/sec or 10 req/sec with API key) - Cached results inherit TTL from underlying entrez_search and entrez_summary calls
