Human leukocyte antigens (HLA) are important genetic markers of tissue identity and accurately reflect ancestral history. The work reported in this paper provides a detailed description of HLA polymorphism in Polynesian and Maori individuals in relation to other populations. Our study concerns HLA classes I and II antigens in Polynesian (N = 36) and Maori (N = 114) subjects genotyped at two digit...
We previously reported the development of genomic‐DNA‐based high‐resolution genotyping methods for SLA‐DQB1 and DRB1. Here, we report the successful typing of SLA‐DQA using similar methodological principles. We designed a method for comprehensive genotyping of SLA‐DQA using intronic sequence information of SLA‐DQA exon 2 that we had obtained from 12 animals with different SLA‐DQB1 genotypes. We expanded...
Two novel HLA‐B alleles were characterized. HLA‐B*37:34 shows two nucleotide differences regarding B*37:10 at codons 79 (CGC>CGG) and 80 (ACC>ATC), resulting in one amino acid replacement at position 80 (T>I). HLA‐B*44:152 differs from B*44:02:01 in one nucleotide at codon 81 (GCG>ACG) giving rise to a leucine to threonine substitution at position 81.
Homozygosity for a nonsense mutation in the fucosyltransferase 2 (FUT2) gene (rs601338G>A) leads to the absence of ABH blood groups (FUT2 non‐secretor status) in body fluids. As the secretor status has been shown to be a major determinant for the gut microbial spectrum, assumed to be important in the gut immune homeostasis, we studied the association of rs601338‐FUT2 with celiac disease (CelD)...
The tumor necrosis factor alpha (TNFA) promoter region exhibits several polymorphisms, which have been hypothesized to influence gene expression, thereby associating positively or negatively with inflammatory conditions. Many studies have focused on single nucleotide polymorphisms (SNPs) taking not into account additive or inverse effects between different SNPs. We typed 1,021 healthy Caucasian volunteer...
HLA‐A*02:335 shows one nucleotide different from HLA‐A*02:07:01 at position 173T>A and HLA‐A*02:370 has a single nucleotide polymorphism at position 886 C>G compared with HLA‐A*02:03:01.
In this study, we have investigated the expression of the tumor antigen sperm protein 17 (SP17) in a large panel of human cancers and compared it with the expression of two well‐characterized families of tumor antigens, melanoma‐associated antigen‐A (MAGE‐A) and G antigen (GAGE). We found that SP17 was expressed in many cancer types with an overall frequency of 12%. SP17 was most frequently expressed...
Cynomolgus macaques (Macaca fascicularis, Mafa) have emerged as an important animal model for infectious disease and transplantation research. Extensive characterization of their major histocompatibility complex (MHC) polymorphism regions therefore becomes urgently required. In this study, we identified 41 MHC class I A nucleotide sequences in 34 unrelated cynomolgus macaques of Vietnamese origin...
A*29:39 differs from A*29:02:01 by three clustered amino acid replacements at α1 domain, T73>I73, A76>V76 and N77>D77. A*29:40 shows one nucleotide difference regarding A*29:02:01 allele, resulting in one amino acid substitution at position 154, E154>G154.
HLA‐A*03:143 has one nucleotide change from A*03:01: 01:01 at nt 406 from G to C, resulting in an amino acid change at codon 112 of exon 3 from Gly to Arg.
