Typing of DNA from 94 unrelated children with celiac disease (CD) with HLA-DQA1 and -DQB1 allele-specific oligonucleotide probes revealed that all but one (i.e., 98.9%) may share a particular combination of a DQA1 and a DQB1 gene. These genes are arranged in cis position on the DR3DQw2 haplotype and in trans position in DR5DQw7/DR7DQw2 heterozygous individuals. Thus, most CD patients may share the same cis- or trans-encoded HLA-DQ alpha/beta heterodimer.
采用HLA - DQA1和 - DQB1等位基因特异性寡核苷酸探针,对94名无亲缘关系的乳糜泻(CD)患儿进行DNA分型,结果显示,除1名患儿外(即98.9%),所有患儿可能共享一种特定的DQA1和DQB1基因组合。这些基因在DR3DQw2单倍型上呈顺式排列,在DR5DQw7/DR7DQw2杂合个体中呈反式排列。因此,大多数CD患者可能共享相同的顺式或反式编码的HLA - DQα/β异二聚体。
