Abstract:
We have applied genotyping methods of PCR-SSOP and PCR-RFLP to three, bi-allelic platelet specific antigen systems HPA-1 (Pla), HPA-3 (Bak) and HPA-5 (Br). This combination of techniques offers flexibility for high volume or rapid typing. The phenotype and genotype frequencies of alleles from the three systems differ significantly between the Yuendumu Australian Aboriginals (Wailbri) and Australian Caucasians. The major differences are the very low frequencies of HPA-1b and HPA-3b in Yuendumu Aboriginals which are potentially relevant to platelet transfusion in patients of Australian Aboriginal descent.
