A good recent review paper on MHC evolution is:
Klein, J., and A. Sato (1998). Birth of the Major Histocomptibility
Complex. Scand. J. Immunol. 47:199-209.
They argue that i) the "class III" regions *really* are not part of the
MHC, and ii) the evolution of the peptide-binding domain was by exon
shuffling rather than alteration of an immunoglobulin-superfamily-type
gene. It isn't exactly the LD stuff you requested, but it does put the
region in an evolutionary context.
There are several recent papers in "Immunogenetics" on shared class I
alleles across different primate species - interesting as some are
several million years diverged, and also a point on the stability of
For a *reason* why such allelic variation is compressed into so few
Nowak, M.A., K. Tarczy-Hornoch, and J.M. Austyn 1998. The optimal number
of major histocompatibility complex molecules in an individual. Proc.
Natl. Acad. Sci. (USA) 89:10896-10899.
I'm sure there are better refs near at hand for LD as in your question,
so I'll keep my eye out and will post them if they jump out at me.
