From GeneWeaver Wiki
- GeneWeaver uses the concept of Homology Mapping to expand search and analysis capabilities beyond a single species. Currently, we rely on data provided by Homologene to assert homoloy between clustered sets of reference gene ids. That is, GeneWeaver creates a set of unique id clusters (representing Entrez, Ensembl, Gene Cards, etc.) representing specific genes, these clusters are connected across species using mappings established by Homologene. We also recognize the utility of Panther to assert homologs based on evolutionary relationships and we hope to include these annotations in the future.
