PG - 35-47 LID - 10.1111/j.1399-0039.2010.01465.x [doi] AB - We investigated polymorphic Alu insertion (POALIN) frequencies at five loci in the major histocompatibility complex (MHC) class II genomic region to determine their allele and haplotype frequencies and associations with the human leukocyte antigen (HLA)-DRB1 and -DQB1 genes for 100 Japanese, 174 Australian Caucasians and 67 HLA reference cell lines obtained from different ethnic groups. The POALINs varied in frequency between 11% and 57% with significant differences between the Japanese and Caucasians at three loci. One POALIN locus deviated significantly from Hardy-Weinberg equilibrium (HWE) and four POALIN loci were in significant linkage disequilibrium and had a high percentage association with a variety of HLA-DRB1 or -DQB1 two-digit alleles. Inferred haplotype analysis among two-locus, five-locus and seven-locus haplotype structures showed maximum differences between the Japanese and Caucasians with the seven-locus haplotypes. The most common multilocus haplotype in Caucasians was DRB1*1501/DQB1*0602/AluDQ1/AluDRB1/AluORF10/AluDPB2 (6.7%), whereas the second most common allele HLA-DRB1*15 (17.5%) in Japanese was associated with three or four Alu insertions. The HLA class II POALINs also differentiated within and between HLA-DRB1 super-haplotypes DR1, DR8, DR51, DR52 and DR53. This is the first comparative population study of multilocus POALINs in the HLA class II region, which shows that POALINs whether investigated alone or together with the HLA class II alleles are informative genetic markers for the identification of allele and haplotype lineages and variations within the same and/or different populations.
