Ensembl Get Cross References

Overview

Get all external database cross-references for an Ensembl stable identifier. Returns linked records from HGNC, EntrezGene, UniProt, GeneCards, Reactome, MIM/OMIM, ArrayExpress, and other databases. Essential for mapping between Ensembl and other identifier systems, discovering related database entries, or building cross-database links for a gene. Can filter by specific external database. Example: 'ENSG00000141510' (TP53) returns 157 cross-references across 11 databases including HGNC:11998, EntrezGene:7157, GeneCards:TP53, MIM_GENE:191170, and Reactome pathways.
