Request: add non-human genes

[SESDNA]

Hello!
May I suggest that you add support for non-human genes to 1) enable use in model organisms, 2) learn more biology. A good place to start would be to add Gene Descriptions for the eight other species from Alliance Genome [https://www.alliancegenome.org/downloads#gene-descriptions]. I am also attaching a files for mouse and zebrafish in case you are interested in trying it out.

Thank you for this amazing work!
