摘要: 目的 应用靶向测序技术探索川崎病(KD)丙种球蛋白无反应易感基因,筛选KD高危人群。方法 选择 2016年12月至2018年10月收治的190例KD患儿,其中静脉注射丙种球蛋白(IVIG)无反应33例、敏感151例,以及99例 健康儿童。采集外周静脉血全基因组DNA,采用靶向捕获测序技术,分析比较基因差异位点。结果 KD患儿和健康儿童 之间FCGR3A(rs77144485)、IL15RA(rs2228059)、IL-6(rs13306435)基因型的差异均有统计学意义(P<0.05)。IVIG无反 应和敏感KD患儿之间,在位于IL-2RB、IL-24、BMPR1A、GZMB、KDR、KIR2DS4、CARD11、CHUK等基因区域的10个单 核苷酸多态性位点的基因型频率差异有统计学意义(P均<0.05)。 结论 靶向捕获测序技术初步筛选出IL-2RB、IL-24、 BMPR1A、GZMB、KDR、KIR2DS4、CARD11、CHUK等KD 丙种球蛋白无反应型易感基因。

Abstract:  Objective To identify genes associated with intravenous immunoglobulin (IVIG) resistance in Kawasaki disease (KD) through targeted enrichment technology, and to screen the high-risk population of KD. Method A total of 190 KD patients (33 IVIG non-responders and 151 IVIG responders) admitted from December 2016 to October 2018 and 99 healthy check-up children were selected. The genomic DNA of peripheral venous blood from the patients was collected, and the gene differences between the two groups were analyzed and compared by targeting capture and sequencing technology. Result There were significant differences in genotypes of FCGR3A (rs77144485), IL15RA (rs2228059) and IL6 (rs13306435) between KD children and healthy children (all P<0.05). There were significant differences in genotype frequencies of 10 single nucleotide polymorphisms (SNPs) loci in IL-2RB, IL-24, BMPR1A, GZMB, KDR, KIR2DS4, CARD11 and CHUK between IVIG resistant group and IVIG responsive group (all P<0.05). Conclusion IL-2RB, IL-24, BMPR1A, GZMB, KDR, KIR2DS4, CARD11, CHUK were found to be significantly different in IVIG resistant group and IVIG responsive group by targeted enrichment technology.
