NCBIDatasets Get Orthologs

Get orthologous genes across species for a given NCBI Gene ID. Returns orthologs identified by NCBI's Ortholog pipeline, including gene symbols, species, and gene types for each ortholog. Useful for comparative genomics and cross-species gene function studies. Example: gene_id 7157 (TP53) returns mouse Trp53, rat Tp53, zebrafish tp53, etc.
