摘要: 目的 研究分析1例ABO疑难血型患者的血型血清学和分子生物学特征,为此类患者的临床输血提供输注建议。方法 采用血清学方法鉴定ABO血型,用吸收放散试验做进一步血清学检测,再利用基因测序技术分析样本ABO基因序列。结果 患者ABO血清学实验呈现正反定型不一致;吸收放散试验检测出弱A抗原;基因测序显示其携带c.374+5G>A基因突变,且c.374+5G>A合并c.467C>T基因突变在ISBT数据库中为首次发现。结论 基因测序技术有助于解析疑难血型的分子生物学基础,并为输血安全和实现精准输血提供循证学重要价值。

Abstract: Objective To investigate a case of ABO difficult blood group patient for serological and molecular biological characteristics, and provide transfusion recommendations for the clinical transfusion in the patients. Methods The ABO blood group was identified by serological method, further serological detection was conducted by absorption-elution test, and the ABO gene sequence was analyzed by gene sequencing technology. Results The patient's ABO serological test showed inconsistent in forward and reverse typing; weak A antigen was detected by absorption-elution test; gene sequencing revealed that it carried the c.374+5G>A gene mutation, and the c.374+5G>A combined with c.467C>T gene mutations were found for the first time in the ISBT database. Conclusion Gene sequencing technology helped to elucidate the molecular biological basis of difficult blood groups, and provided evidence-based significant value for transfusion safety and the implementation of precision transfusion.
