摘要: 目的 应用SNaPshot技术对ABO血型进行基因型检测。 方法 采集107份已知血型(由血清学获得)的云南无关个体静脉血提取DNA,运用SNaPshot Multiplex试剂盒对ABO血型基因的第261、297、681、703、802和803核苷酸位置的6个SNP位点进行复合扩增检测,计算相关遗传学参数。 结果 107份血样中A、B、OA、OG 4个等位基因的频率分别为0.355 1、0.168 2、0.230 0、0.247 6,其中AG和顺式AB未检出,ABO基因分型结果与血清学检验的结果一致。 结论 SNaPshot技术适用于ABO血型基因的分型。

Abstract: Objective To detect the genotype of ABO blood group by SNaPshot technology. Methods DNA were extracted from the peripheral blood samples with known blood groups (obtained by serology) of 107 unrelated individuals in Yunnan. Six SNP loci of the 261th, 297th, 681th, 703th, 802th, and 803th nucleotide positions were detected by SNaPshot Multiplex kit, and relevant genetics parameters were calculated. Results In 107 blood samples, the allele frequencies of types A, B, OA, and OG were 0.355 1, 0.168 2, 0.230 0 and 0.247 6, respectively, while that of types AG and cis AB were not detected. The genotyping results of ABO blood group were consistent with that of serologic testing. Conclusion SNaPshot technology can be adapted for genotyping of ABO blood group.
