| Popis: | Objective To research the genetic polymorphism of HPA 1-6/10/15/21 in platelet donors in Zhongshan area, and establish a gene bank of platelet donors with HPA locus. Methods The HPA 1-6/10/15/21 system genotyping was performed by Real time fluorescent PCR combined with TaqMan probe technology on 192 platelet donors in Zhongshan area, and the genotype frequency and gene frequency were calculated. Results Only HPA-aa genotype was found within HPA-4/10, and no allele HPA-b had been detected. The majority of HPA-1, 2, 5, 6 and 21 genotypes were aa. HPA-3 and HPA-15 showed high heterozygosity, with genotype frequency of 0.307 3, 0.494 8 and 0.197 9 for HPA- 3aa, HPA-3ab and HPA-3bb, while 0.270 8, 0.505 2 and, 0.224 0 for HPA -15aa, HPA-15ab and HPA-15bb, respectively. Conclusion The distribution characteristics of HPA 1-6 /10/15/21 of platelet donors in Zhongshan shows regional differences compared with similar researches from other regions. The establishment of HPA gene bank is helpful to avoid alloimmunization caused by incompatible platelet transfusion. |
