Genotyping of ABO Blood Group in Partial Population of Yunnan Province by SNaPshot Technology

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.
