Abstract excerpt
The extreme polymorphism of mammalian major histocompatibility (MHC) Class I and Class II alleles has been attributed to inbreeding avoidance, heterozygote advantage and pathogen driven selection for rare MHC alleles. However, MHC alleles can be classified into a limited number of allele supertypes based on the specificity of their peptide binding grooves (about 10 supertypes in the case of human MHC Class I...
