text: user460: I'm using snpEff to annotate some VCFs and getting some spurious annotations that don't have transcript ids. Some of these annotations have a gene name followed by ampersand such as PCDHB@ and I'm not finding any explanation in the docs.  
  Any idea what this refers to? Entire gene family? 
  Thanks.  
  
  user298: The @ at the end of a name denotes a "gene cluster in chromosome region". This is mentioned in the official HUGO nomenclature guidelines in the "Characters reserved for specific usage" section:
  
  It's also mentioned in the GeneCards documentation:
