摘要: 目的 探讨三代基因测序技术(TGS)在Kidd血型抗原弱表达样本中检测的临床意义。方法 收集新疆自治区人民医院就诊患者样本并收集患者信息,应用血清学方法检测Jka、Jkb抗原,对结果弱表达样本9例进行Kidd血型基因全长单分子实时测序技术(第三代高通量测序)获得其基因多态性并统计分析。结果 获得此次检测Kidd血型基因主要突变位点:c.588A>G、c.838G>A、c.130G>A;此外还发现5例样本带有新的基因突变类型,其中2例为纯合子,3例为杂合子,新的突变基因型为:c.499A>G、c.588A>G、c.838G>A,主要见于Jk(b+)表型,等位基因名称为JK*02.NEW,9例样本中有7例基因检测结果与血清学结果不同,且均带有ISBT记录或未记录的基因突变位点,同时汇总并分析了突变基因位点特异性及其对应氨基酸改变情况。结论 本研究探索了新疆人群红细胞血型Kidd基因的突变、剪切、折叠以及氨基酸序列,为进一步了解本地区血型特异性奠定基础,为今后构建三维蛋白模型提供了依据。

Abstract: Objective To investigate the clinical significance of third-generation gene sequencing (TGS) in detecting Kidd blood group antigen in weakly expressed samples. Methods Samples of patients in Xinjiang Autonomous Region People's Hospital were collected, Jka and Jkb antigens were detected by serological methods, and 9 cases of weakly expressed samples of Kidd blood group genes were subjected to full-length single-molecule real-time sequencing technology (third-generation high-throughput sequencing) to obtain their gene polymorphisms and statistically analyzed. Results The main mutation sites of the Kidd blood group gene were detected in this study: c.588A>G, c.838G>A, and c.130G>A. In addition, 5 samples were found to have new gene mutation types, with 2 being homozygous and 3 heterozygous. The new mutation gene types were: c.499A>G, c.588A>G, and c.838G>A, which are mainly seen in the Jk(b+) phenotype. The allele name for the new mutation is JK*02.NEW. In 9 samples, 7 of the genetic test results were different from the serological results, and all of them had ISBT-recorded or unrecorded gene mutation sites. At the same time, the specificity of the mutation gene sites and the corresponding amino acid changes were summarized and analyzed. Conclusion The present study investigated the mutation, splicing, folding, and amino acid sequence of the Kidd gene in the Xinjiang population. This research lays a solid foundation for gaining further insights into the specificity of blood groups in this region and provides a fundamental basis for future construction of three-dimensional protein models.
