摘要:

目的:探索人类白细胞抗原(HLA)DRB1DPA1低分辨等位基因型与维吾尔族霍奇金淋巴瘤(HL)易感性的关系。方法:采用病例-对照研究(1∶2)和DNA直接测序分型(SBT)法,对40例维吾尔族HL患者和80名健康体检者进行HLA-DRB1DPA1基因分型,分析其与HL发病的相关性。结果:对于HLA-DRB1DPA1基因,病例组分别检出12和3个低分辨等位基因,对照组中分别检出13和4个低分辨等位基因;HLA-DRB1DPA1基因座位上等位基因频率分布均满足Hardy-Weninberg遗传平衡检验(P > 0.05)。维吾尔族HL中HLA-DRB1*15DPA1*03DPA1*02-DRB1*13基因表达均高于维吾尔族健康对照组(P均<0.05);而HLA-DRB1*07基因频率低于维吾尔族健康对照组(P < 0.05)。结论HLA-DRB1DPA1基因多态性可能与维吾尔族HL的发病存在关联,在揭示HL的发病机制方面有研究价值。

Abstract:

OBJECTIVE: To explore the relationship between the human leukocyte antigen (HLA) DRB1,DPA1 low resolution type alleles and susceptibility of Uighurs to develop Hodgkin's lymphomas (HL). METHODS: Using a case-control study design,DNA direct sequencing classification method (SBT) was used to detect alleles in HLA-DRB1 and expression of HLA-DPA1 gene among 40 cases of Uighur patients and 80 healthy controls. The HLA-DRB1 and DPA1 allele frequencies between the two groups were compared. The correlation between them with the pathogenesis of HL was analyzed. RESULTS: HLA-DRB1 and DPA1 low resolution alleles were detected 12,3 types in the case group and 13,4 types in the control group,the frequency distribution of which met the Hardy-Weninberg genetic balance test (P > 0.05). The results show that HLA-DRB1*15,DPA1*03 and DPA1*02-DRB1*13 gene frequencies were significantly more frequent in the Uighur patients than the controls (P=0.016,OR=3.476;P=0.002,OR=4.248;P=0.037,OR=3.028,respectively);HLA-DRB1*07 gene frequencies between the two groups were statistically significant (P=0.025,OR=0.314). CONCLUSION: HLA-DRB1,DPA1 gene polymorphism may be closely associated with the onset of HL among Uighurs and with pathogenesis of HL.
