近日,刊登在国际杂志Nature Communications上的一篇研究论文中,研究者报告了与霍奇金淋巴瘤的易感性相关的新遗传变异体。
这些发现为霍奇金淋巴瘤的遗传成分提供了进一步支持,也让我们对这种疾病的潜在病因有了新认识。
罹患霍奇金淋巴瘤有一个已知的家族性风险,这种风险背后的其中一些遗传因素已被发现。
现在,Richard Houlston及同事将来自不同研究工作的以前发表的数据相结合,生成了一个由1465个霍奇金淋巴瘤病例和6417个对照组组成的数据集。在此基础上,他们识别出两个新的遗传变异体3p24.1和6q23.3,二者均与罹患霍奇金淋巴瘤的风险相关。(生物谷Bioon.com)

In addition to HLA, recent genome-wide association studies (GWASs) of Hodgkin’s lymphoma (HL) have identified susceptibility loci for HL at 2p16.1, 8q24.21 and 10p14. In this study, we perform a GWAS meta-analysis with published GWAS (totalling 1,465 cases and 6,417 controls of European background), and follow-up the most significant association signals in 2,024 cases and 1,853 controls. A combined analysis identifies new HL susceptibility loci mapping to 3p24.1 (rs3806624; P=1.14 × 10?12, odds ratio (OR)=1.26) and 6q23.3 (rs7745098; P=3.42 × 10?9, OR=1.21). rs3806624 localizes 5′ to the EOMES (eomesodermin) gene within a p53 response element affecting p53 binding. rs7745098 maps intergenic to HBS1L and MYB, a region previously associated with haematopoiesis. These findings provide further insight into the genetic and biological basis of inherited susceptibility to HL.
