beta-2 microglobulin alleles

[Ian A. York]

Perhaps someone out there can save me a lot of plowing through 
references.  How many human and mouse alleles of beta-2 microglobulin are 
there?  (I had this information and I seem to have lost the paper.  It 
was probably out of date anyway.) 

Thanks.  

Ian
