MGI HomoloGene Information

MGI loads vertebrate homology data from NCBI HomoloGene, which programmatically detects homologs among the genome features of completely sequenced eukaryotic genomes (see: HomoloGene Build Procedure).

MGI includes homology for the following selected vertebrate species from HomoloGene:
 - human
 - mouse
 - rat
 - cattle
 - chicken
 - chimpanzee
 - dog
 - monkey, Rhesus
 - western clawed frog (Xenopus tropicalis)
 - zebrafish

These are a subset of the total species represented in HomoloGene Classes at NCBI.
Additional species may be present in an NCBI HomoloGene Class than appear in MGI.
