HLA-DR3-DQ2 was typed in combination with HLA-DR7-DQ2 to screen for the HLA-DQ2 haplotype. The histological, analytical and clinical characteristics of the subjects were recorded.ResultsA total of 91 coeliac patients were diagnosed: 96.7% carried HLA-DQ2 and 4.4% carri...
Human leukocyte antigen (HLA) haplotype DR3-DQ2 is associated with dosage-dependent increases in risk for celiac disease autoimmunity and celiac disease in young children, according to astudy publishedin the July 3 issue of theNew England Journal of Medicine. Although most patients with celiac dis...

某一个体HLA抗原特异性型别称为表型(phenotype);HLA基因在体细胞两条染色体上的组合称为基因型(genotype);HLA基因在同一条染色体上的组合称为单体型(haplotype)(表5-2)。 二倍体(diploid)生物的每一细胞均有两个同源染色体组,分别来自父母双方。故...
Nomenclature issues. Some older studies may refer to DR15 or 16 as DR2 and DQ5 and DQ6 as DQ1 therefore a haplotype DR2-DQ1 is usually referring to DR15-DQ6 but could be referring to DR16-DQ5. DR5 is used to refer to DR11 and DR12, in which case DQ3 might be used. In the...
1.单倍型遗传单倍型(haplotype)是指一条染色体上HLA各位点基因紧密连锁组成的基因单位。人体细胞为二倍体型,两个单倍型分别来自父亲和母亲,共同组成个体的基因型(genotype)。由于一条染色体上HLA各位点的距离非常近,很少发生同源染色体之间的交换,因此新代的HLA以单倍型为单位将遗传信息传给子代。例如父亲的基因型为ab,母...
II 类 MHC 分子由 2 条多肽(α [α] 和β [β])链组成;每条链都有一个肽结合结构域、一个 Ig 样结构域和一个带有细胞质尾部的跨膜区域。两条多肽链均由 6 号染色体的 HLA-DP、HLA-DQ 或 HLA-DR 区域中的基因编码。对 II 类分子有反应的 T 细胞表达 CD4,通常是辅助细胞。 The MHC class III ...
Next, we highlight HLA alleles with supported associations that are individual to or variable across HHVs (Fig.1C).B*08mirrorsA*01associations. Although both allotypes are part of the long-range A1-B8-DR3-DQ2 haplotype found at high frequency in Europeans, theB*08association with HL risk...
Coeliac disease patients carry conserved HLA-DR3-DQ2 haplotypes revealed by association of TNF alleles The existence of additional independent risk-modifying loci in the HLA complex is still being debated. The DR3-DQ2 haplotype has been studied most, but... AS Louka,BA Lie,B Talseth,... ...
Autoimmune-associated HLA-B8-DR3 haplotypes in Asian Indians are unique in C4 complement gene copy numbers and HSP-2 1267A/G The classical AH8.1 (HLA-A1-B8-DR3-DQ2) is the most common Caucasian haplotype, associated with several autoimmune diseases, immunologic hyperreactivity an... Gurvinder...
