  The `@` at the end of a name denotes a "gene cluster in chromosome region". This is mentioned in the official [HUGO nomenclature guidelines](https://www.genenames.org/about/guidelines/) in the "Characters reserved for specific usage" section:
  
  [![[HUGO reserved characters table](https://i.sstatic.net/Ywv8s.png)](https://i.sstatic.net/Ywv8s.png)
  
  It's also mentioned in the [GeneCards documentation](https://www.genecards.org/Guide/GeneCard):
