6p21.31、6q23.3、11q23.1、16p11.2和20q13.12上发生突变可影响HL的风险。

摘要:

为进一步加深我们对霍奇金淋巴瘤(HL)的遗传易感性的认识,Amit Sud等人对7个全基因组关联研究()包含5325例HL和22423例对照)进行Meta分析。

研究人员在6p21.31(rs649775,p=2.11×10-10)、6q23.3(rs1002658,p=2.97×10-8),11q23.1(rs7111520,p=1.44×10-11),16p11.2(rs6565176,p=4.00×10-8)和20q13.12(rs2425752,p=2.01×10-8)上发现了5个新的HL风险位点。

在5个新风险位点和13个已知风险位点的基因表达、组蛋白修饰和原位启动子捕获Hi-C数据集成分析提示生发中心反应功能障碍、T细胞分化和功能紊乱以及NF-κB组成性激活均是易感性的机制。

本研究进一步揭示了霍奇金淋巴瘤的遗传易感性和生物学特征。
