Abstract
The Oka blood group antigen basigin (BSG or CD147) is an erythrocyte receptor for the PfRh5 protein from Plasmodium falciparum. A recent study has shown that the PfRh5–BSG interaction is essential for erythrocyte invasion by P. falciparum. In this study, 6 SNPs in the BSG gene were investigated in 312 adult patients with P. falciparum malaria (109 cerebral malaria and 203 mild malaria patients) living in northwest Thailand. To examine the association between BSG SNPs and cerebral malaria, the allele and haplotype frequencies were compared in cerebral and mild malaria patients. Nonsynonymous SNPs were not assessed in the association analysis. The results showed that common BSG polymorphisms and haplotypes were not significantly associated with cerebral malaria. In conclusion, common SNPs in BSG do not influence the risk of cerebral malaria in the Thai population.
