If I have messed this up I want to be clear. The article "MHC Polymorphism
and Human Origins", Scientific American, Dec. 1993, p. 78, has a table on
that page of all the alleles in the MHC complex.
As I read it, there are 3 genes, the DRB1,DRB2, and DRB3. Under the DRB1
they list "known alleles" under each locus. I quickly counted them this
morning and there were 60 under DRB1 (unless I miscounted) , none under DRB2,
and 4 alleles under DRB3.
Can you take a look at that article and tell me what, if anything, I have
done wrong. The alleles are very unevenly distributed among the 3 genes
according to this article.
thanks
