摘要: 目的 调查并分析无锡地区无偿献血者ABO亚型血型血清学及分子生物学特征。方法 2016年5月~2019年6月,有19例无偿献血者标本经血型血清学初步判定为ABO亚型。14/19例标本进行分子生物学检测,其中11例同时采用PCR-SSP(序列特异性引物聚合酶链反应)方法及DNA测序方法进行ABO基因检测,另3例仅采用了DNA测序方法检测。结果 120 118名无偿献血者中,用血型血清学方法检出ABO亚型的频率约为1.6/万,且B亚型数量多于A亚型;分子生物学检测获得Ael02、A201、Bw27、Bel03、Bw22、B310、A217、CisAB01、B(A)02九种ABO突变等位基因;3例标本在第1-7号外显子未见异常,发现1例新等位基因(GenBank:MT281528)。结论 用血型血清学、PCR-SSP和DNA基因测序三种方法结合更能准确地鉴定ABO亚型。

Abstract: Objective To analyze the serological and molecular characteristics of ABO subgroups among blood donors in Wuxi. Methods A total of 19 samples from blood donors between May 2016 and June 2019 were preliminarily identified as ABO subgroup using serological testing. Fourteen samples were identified using molecular biology techniques, 11 of which were identified by both Polymerase Chain Reaction Sequence-specific Primer (PCR-SSP) and DNA sequencing and the other 3 samples were only identified by DNA sequencing. Results Among 120 118 blood donors, the frequency of ABO subgroup using serologic testing was approximately 1.6/10 000, and the number of B subgroup was more than that of A subgroup. Nine ABO mutant alleles, including Ael02, A201, Bw27, Bel03, Bw22, B310, A217, cisAB01, B(A)02 were found. Moreover, no mutation in 3 samples were charactered in exon 1-7 of the ABO gene, and a new allele was found (GenBank: MT281528). Conclusion A combination of serologic testing, PCR-SSP and DNA sequencing can more accurately identify ABO subgroups.
