I remember reading that chimps, I think, showed more
polymorphism (for microsatellites or SNPs, can't remember
which) than humans, indicative of a past bottleneck in
human population size. Of course, I can't find the
reference now. A quick search of Medline pulled out, for
Gagneux P, Varki A.
Genetic differences between humans and great apes.
Mol Phylogenet Evol. 2001 Jan;18(1):2-13. Review.

the abstract of which refers to polymorphisms
Adams EJ, Cooper S, Thomson G, Parham P.
Common chimpanzees have greater diversity than humans at two
of the three highly polymorphic MHC class I genes.
Immunogenetics. 2000 May;51(6):410-24.

Back to MHC I'm afraid. However, I got 772 hits searching on
"primates human polymorphism" and only checked a few.
