Abstract
The study of the association of the Human Leukocyte Antigen (HLA) alleles and polymorphic retrotransposons such as Alu, HERV, and LTR at various loci within the Major Histocompatibility Complex allows for a better identification and stratification of disease associations and the origins of HLA haplotypes in different populations. This paper provides sequence and association data on two structurally polymorphic MER9-LTR retrotransposons that are located 54 kb apart and in close proximity to the multiallelic HLA-A gene involved in the regulation of the human immune system. Direct DNA sequencing and analysis of the PCR products identified DNA nucleotide variations between the MER9-LTR sequences at the two loci and their associations with HLA-A alleles as potential haplotype and evolutionary markers. All MER9-LTR sequences were haplotypic when associated with common HLA-A alleles. The number of SNP loci was 2.5 times greater for the solo LTR at the AK locus, which is located closer to the HLA-A gene than the solo or 3' LTR at the HG locus. Our study shows that the nucleotide variations of the MER9-LTR DNA sequences are additional informative markers in fine mapping HLA-A genomic haplotypes for future population, evolutionary, and disease studies.

Abstract
The frequency and HLA-A allelic associations of a HERVK9 DNA structural polymorphism located in close proximity to the highly polymorphic HLA-A gene within the major histocompatibility complex (MHC) genomic region were determined in Japanese, African Americans, and Australian Caucasians to better understand its human population evolutionary history. The HERVK9 insertion or deletion was detected as a 3' LTR or a solo LTR, respectively, by separate PCR assays. The average insertion frequency of the HERVK9.HG was significantly different (P < 1.083e(-6)) between the Japanese (0.59) and the African Americans (0.34) or Australian Caucasians (0.37). LD analysis predicted a highly significant (P < 1.0e(-5)) linkage between the HLA-A and HERVK9 alleles, probably as a result of hitchhiking (linkage). Evolutionary time estimates of the solo, 5' and 3' LTR nucleotide sequence divergences suggest that the HERVK9 was inserted 17.3 MYA with the first structural deletion occurring 15.1 MYA. The LTR/HLA-A haplotypes appear to have been formed mostly during the past 3.9 MY. The HERVK9 insertion and deletion, detected by a simple and economical PCR method, is an informative genetic and evolutionary marker for the study of HLA-A haplotype variations, human migration, the origins of contemporary populations, and the possibility of disease associations.

Abstract
The genomic sequences within the alpha-block (approximately 288-310 kb) of the human and chimpanzee MHC class I region contains ten MHC class I genes and three MIC gene fragments grouped together within alternating duplicated genomic segments or duplicons. In this study, the chimpanzee and human genomic sequences were analyzed in order to determine whether the remnants of the ERVK9 and other retrotransposon sequences are useful genomic markers for reconstructing the evolutionary history of the duplicated MHC gene families within the alpha-block. A variety of genes, pseudogenes, autologous DNA transposons and retrotransposons such as Alu and ERVK9 were used to categorize the ten duplicons into four distinct structural groups. The phylogenetic relationship of the ten duplicons was examined by using the neighbour joining method to analyze transposon sequence topologies of selected Alu members, LTR16B and Charlie9. On the basis of these structural groups and the phylogeny of the duplicated transposon sequences, a duplication model was reconstructed involving four multipartite tandem duplication steps to explain the organization and evolution of the ten duplicons within the alpha-block of the chimpanzee and human. The phylogenetic analysis and inferred duplication history suggests that the Patr/HLA-F was the first MHC class I gene to have been fixed and not required as a precursor for further duplication within the alpha-block of the ancestral species.

Abstract
MICA and MICB, as members of the major histocompatibility complex (MHC) class I-chain-related genes (MIC), encode stress-inducible glycoproteins that act as activating ligands for NKG2D and gammadelta T-cell receptor-bearing cells. We here describe the identification of eight novel MICB variants, including a null allele, which were identified in peripheral blood leukocytes of gastric MALT lymphoma patients. Only two of the novel alleles are characterized by point mutations, whereas the other variants display a recombination of known exonic MICB sequences that may be best explained by intragenic conversions. The novel MICB null allele is characterized by a Cytosin (C) deletion in a stretch of four Cs beginning from nucleotide 135 of exon 2 that leads to a premature stop codon (TGA) at codon 66.

Abstract
All expressed human MHC class I genes (HLA-A, -B, -C, -E, -F, and -G) have functional orthologues in the MHC of the common chimpanzee (Pan troglodytes). In contrast, a nonclassical MHC class I gene discovered in the chimpanzee is not present in humans or the other African ape species. In exons and more so in introns, this Patr-AL gene is similar to the expressed A locus in the orangutan, Popy-A, suggesting they are orthologous. Patr-AL/Popy-A last shared a common ancestor with the classical MHC-A locus >20 million years ago. Population analysis revealed little Patr-AL polymorphism: just three allotypes differing only at residues 52 and 91. Patr-AL is expressed in PBMC and B cell lines, but at low level compared with classical MHC class I. The Patr-AL polypeptide is unusually basic, but its glycosylation, association with beta(2)-microglobulin, and antigenicity at the cell surface are like other MHC class I. No Patr-AL-mediated inhibition of polyclonal chimpanzee NK cells was detected. The Patr-AL gene is present in 50% of chimpanzee MHC haplotypes, correlating with presence of a 9.8-kb band in Southern blots. The flanking regions of Patr-AL contain repetitive/retroviral elements not flanking other class I genes. In sequenced HLA class I haplotypes, a similar element is present in the A*2901 haplotype but not the A*0201 or A*0301 haplotypes. This element, 6 kb downstream of A*2901, appears to be the relic of a human gene related to Patr-AL. Patr-AL has characteristics of a class I molecule of innate immunity with potential to provide common chimpanzees with responses unavailable to humans.

Abstract
The genomic matching technique (GMT) improves survival following bone marrow transplantation (BMT) between unrelated donor and recipient pairs correlating with a decrease in incidence and severity of graft-versus-host disease (GvHD). The principles of this technique are based on the duplication and polymorphic characteristics of the major histocompatibility complex (MHC). Specifically, the beta block GMT matches for a 300 kb region that contains the human leukocyte antigen (HLA-B and -C) genes as well as other non-HLA genes such as the natural killer cell receptor ligand PERB11 (MIC). The block contains two large segmental duplications. One results in two PERB11 genes (11.1 and 11.2), the other in two class I genes (HLA-B and -C). With the complete sequencing of the class I region of the MHC in different haplotypes, we can now show that the beta block GMT profiles reflect amplification of the duplicated PERB11 segments and not the duplicated segments containing HLA-B and -C, and yet provide a signature that characterizes the entire block rather than individual loci.
