Behcet's disease (BD) is known to be strongly associated with human leukocyte antigen (HLA) B51in many different ethnic groups. HLA-B51 allele typing of Greek BD patients was performed to study the distribution of B^*5101-B^*5107 alleles in this Greek population. The B51 antigen strongly associated with BD was found to be predominantly encoded by allele B^*5101. As it is now known that the B51 antigen can be encoded by 21 alleles, B^*5101-B^*5121, we performed HLA- B^*5101 allele genotyping among 58 Greek patients with BD. After serological HLA typing, typing of HLA-B^*5101 alleles was performed using the polymerase chain reaction-sequencing-based typing (PCR-SBT) method. The frequency of the B51 antigen was found to be significantly higher in the patient group as compared with the control group. In the genotyping of B51 alleles, 34 out of 44 B51-positive patients possessed B^*5101, and 13 out of the 44 carried B^*5108. In contrast, all of the 9 B51-positive normal controls carried B^* … More 5101. This study revealed a strong association of Greeks with BD, with both B^*5101 and B^*5108.HLA-B^*5101 and HLA-B^*5108 were found to be increased in the patient groups among Italian and Saudi Arabian populations. We performed HLA-B^*51 allele genotyping by PCR-SBT method in order to investigate whether there is any correlation of one particular B51-associated allele with Japanese BD. 96 Japanese patients with BD and 132 healthy volunteers were used. As a result, the phenotype frequency of the B51 antigen was confirmed to be remarkably increased in the patient group as compared to the control group. In the B^*51 allele genotyping, 56 of 57 B51-positive patients were defined as B^*5101 and the remaining one was B^*5102.In contrast, all of 18 B51-positive normal controls were B^*5101. None of the Japanese patients and controls carried HLA-B^*5108 allele. This study revealed that B^*51 allelic distribution in Japanese was different from those in Italian and Saudi Arabian populations, and that the significantly high incidence of HLA-B51 antigen in Japanese BD patient group was caused by the increase of HLA-B^*5101 allele.

已知Behcet疾病（BD）与人类白细胞抗原（HLA）B51在许多不同的种族群体中密切相关。对希腊BD患者进行了HLA-B51等位基因键入，以研究该希腊人群中B^*5101-B^*5107等位基因的分布。发现与BD密切相关的B51抗原主要由等位基因B^*5101编码。众所周知，B51抗原可以由21个等位基因B^*5101-B^*5121编码，我们在58名希腊BD患者中进行了Hla-B^*5101基因分型。血清学HLA键入后，使用基于聚合酶链反应测序的键入（PCR-SBT）方法进行HLA-B^*5101等位基因的键入。与对照组相比，患者组的B51抗原的频率在患者组中明显更高。在B51等位基因的基因分型中，44例B51阳性患者中有34例假定B^*5101，而在44个携带的B^*5108中，有13例。相比之下，所有9 B51阳性的正常对照均携带B^*…更多5101。这项研究表明，在意大利和阿拉伯语的患者中，发现希腊人与BD和B^*5101和B^*5101和B^*5108.hla-B^*5101和Hla-B^*5101和Hla-B^*5108的牢固关联。我们通过PCR-SBT方法进行了HLA-B^*51等位基因基因分型，以研究一种特定的B51相关等位基因与日本BD是否存在任何相关性。使用了96例BD患者和132名健康志愿者。结果，与对照组相比，患者组的B51抗原的表型频率已明显增加。在B^*51等位基因基因分型中，57例B51阳性患者中有56例被定义为B^*5101，其余的患者为B^*5102.在相比之下，所有18 B51阳性的正常对照均为B^*5101。日本患者和对照组没有HLA-B^*5108等位基因。这项研究表明，日语中的B^*51等位基因分布与意大利和沙特阿拉伯人群不同，而日本BD患者组中HLA-B51抗原的显着高入射是由HLA-B^*5101等位基因的增加引起的。较少的
