Evolution of MHC class I genes in higher primates.
The classical major histocompatibility complex (MHC) class I genes are conserved in higher primates. Motifs common to human, chimpanzee and gorilla alleles indicate that class I alleles diverged from ancestral sequences that existed before separation of these species. Analysis of native human populations such as Australian Aborigines and Amerindians shows that HLA-B is characterized by rapid generation of new alleles. HLA-A and -C appear to be evolving more slowly. Comparison of alleles for orthologous class I genes in humans and other primates confirms that similar mechanisms contribute to the generation of new alleles in these species.
