title: [ABO genotyping of Han population in Beijing].
abstract: The aim of this study was to establish a diagnostic method for ABO genotyping and to investigate the distribution of ABO genotype in Beijing Han population so as to understand the distribution characteristics and regularity of ABO genotype. An ABO genotyping method was established by using multiplex-PCR-RFLP and PCR-SSP techniques, and the ABO allele frequency in Beijing Han population was investigated. The results showed that A102, O1 and B allele were more common genes in Beijing Han individuals. And A102 allele was predominant in the phenotype A group in this population. Three O2 alleles were found and no A201 allele was found while gene frequency investigation was performed. No A101A101, A101O2, A102O2, BO2 and O2O2 in this population were discovered. It is concluded that the primary regularity of ABO allele distribution in Beijing Han population is found through this study. It provides basic reference for further study of ABO types.
