Newer gene family pages are available

This is our older gene family page that is no longer maintained. Please go to our new look gene family index to view a complete list of our new maintained gene families. More information can be found in our gene families help page.

We have created a mapping file (Excel) that will map most of the old families to the new. However because we have changed the way we assign families and how we organise them, this file may not map all the old families.

New Beta Site!

Please visit our new HGNC beta site and let us know what you think via the feedback form.
