Abstract:
Objective To establish eight human platelet antigen systems and HLA-Ⅰ antigen donor bank,and to determine the gene frequencies of human platelet antigen(HPA) and HLA-Ⅰin Guangzhou area.Methods A total of 805 blood samples from Chinese Han voluntary platelet donors were included in this study.PCR-SSP was used to detect single-nucleotide polymorphism in HPA systems.Luminex-SSO was used to detect the HLA-Ⅰantigens.Results The distribution of HPA 1,2,3,4,5,6,9,15 was in Hardy-Weiberg equilibrium among study subjects.Allele frequencies of 0.998 and 0.002 were observed for HPA 1a and 1b,0.952 and 0.048 for HPA 2a and 2b,0.553 and 0.447 for HPA 3a and 3b,0.999 and 0.001 for HPA 4a and 4b,0.976 and 0.024 for HPA 5a and 5b,0.982 and 0.018 for HPA 6a and 6b,1 and 0 for HPA 9a and 9b,0.518 and 0.481 for HPA 15a and 15b.The high frequency HLA-Ⅰ alleles were A*02,0.286;A*24,0.162;A*11,0.323;B*46,0.147;B*75,0.100;C*01,0.177;C*03,0.289;C*07,0.179.Conclusions This study confirmed the ethnic and territorial difference of HPA and HLA-Ⅰ.The establishment of HPA and HLA-Ⅰ matched plateletpheresis donor registry is helpful in the improvement in platelet transfusion.
