OrthoDB Search Groups

Search for orthologous groups by gene/protein name in OrthoDB v12. OrthoDB catalogs orthologous groups at different taxonomic levels (vertebrates, metazoa, eukaryotes, etc.), enabling evolutionary analysis of gene conservation. Returns group IDs that can be queried for details. Complements OMA and Ensembl Compara with group-level orthology at deep evolutionary scales. Example: searching 'BRCA1' with species=9606 returns orthologous groups containing BRCA1 at various taxonomic levels.
