Objective To develop a multi-PCR-SSP technique for human platelet antigens(HPAs)-1 to-17bw genotyping.And study on the distribution of HPAs polymorphism in Zhuang population by this technique.Methods We designed various combinations of HPA sequence-specific primers in order to simultaneously amplify several target HPA gene fragments in one PCR reaction by using one multi-primers combination.The results of HPA genotype were read and assigned according to the size of the target fragment and the presence or absence of the fragment.The effectiveness of the multi-PCRSSP technique was evaluated by using 17 HPA reference DNA samples that were provided in 14th Platelet Immunology Workshop and 100 HPA-known DNA samples of platelet donors.Total of 2 659 random samples from unrelated and healthy adults of Zhuang population in Guangxi region were studied for HPA-1 to-17bw genotype and antigens polymorphism by the developed technique.Results There are 16 primers mixes in the multi-PCR-SSP method,and 6 of them are multi-PCR primers combinations mixes in our technical system.100% concordance of genotyping results were showed by the evaluation of using 17 reference DNA samples and 100 DNA samples of known-HPA-genotype platelet donors.The HPAs allele frequencies in Zhuang population were 0.991 5 and 0.008 5 for HPA-1a and-1b;0.956 9 and 0.043 1 for HPA-2a and-2b;0.512 2 and 0.487 8 for HPA-3a and-3b;0.985 0 and 0.015 0 for HPA-5a and-5b;0.985 1 and 0.014 9 for HPA-6a and -6b;0.525 6 and 0.474 4 for HPA-15a and-15b,respectively.There only a / a homozygosis was detected in HPA-4,HPA-7 ~ 14bw,-16 ~ 21bw.And a / a and b / b homozygosis in HPA-2 ~ 3,HPA-6bw and HPA-15 were found.Conclusion In this study,we successfully established a multi-PCR-SSP technique for HPA-1 to-17bw genotyping.It was a rapid and accurate method for HPA genotyping,particularly suitable for large quantity samples' HPA-1 ~ 17bw genotyping.This study showed that the HPAs polymorphism in Zhuang population had their own national characteristics,and the data helps us to know the characteristics of platelet immunological in Zhuang population.
