摘要: 目的 由3例临床疑难用血病例引发设计一种可以快速筛查稀有Di(b-)血型的TaqMan MGB实时荧光PCR方法。方法 采用血清学方法鉴定血型和意外抗体,PCR扩增SLC4A1基因编码区并测序分析DNA序列,TaqMan-MGB实时荧光PCR方法对患者及对照样本DI*A/DI*B基因进行快速鉴定。结果 3例临床病例的抗体鉴定均与试剂红细胞组细胞呈现凝集强度一致的阳性结果,提示体内存在针对抗高频抗原的抗体;通过DNA测序显示该3例样本的SLC4A1基因19外显子2 561 bp处为TT纯合,分子水平确定为稀有Di(a+b-)血型;为实现快速筛选匹配血液设计的实时荧光PCR引物和探针,可以准确鉴定样本的SLC4A1基因型。结论 我们设计的TaqMan-MGB实时荧光PCR方法能够快速、准确、高效的鉴定DI*A、DI*B基因。

Abstract: Objective Design of a real-time PCR method for rapid screening of rare Di(b-) blood types inspired by 3 clinical cases. Methods Blood type and unexpected antibodies were identified by serological methods. The coding region of SLC4A1 gene was amplified by PCR and sequenced to analyze the DNA sequence. Real-time TaqMan-MGB PCR was used for rapid identification of DI*A/DI*B from clinical cases and control samples. Results The unexpected antibody identification of 3 clinical cases was uniformly positive with RBCs, suggesting the presence of unexpected antibodies against high-frequency antigens. DNA sequencing confirmed that the 3 cases were TT at 2561bp in exon 19 of the SLC4A1 gene, which is rare Di(b-) blood type. Real-time fluorescent PCR primers and probes designed for rapid screening of matching blood can accurately identify the SLC4A1 genotype of samples. Conclusion The real-time fluorescent TaqMan-MGB PCR method we designed can quickly, accurately and efficiently identify DI*A and DI*B genes, and can be used to rapidly screen Di(b-) blood to meet the clinical blood needs.
