ABSTRACT
Objective: To know whether the effect of interferon-induced protein with tetratricopeptide repeats (IFIT) 1 polymorphism influences the susceptibility of cerebral malaria outcome. Methods: Case-control association study was performed among 314 Thai patients (110 with cerebral malaria and 204 with uncomplicated malaria) infected with Plasmodium falciparum. Genotyping for five tag-single nucleotide polymorphisms of IFIT1 was performed by endpoint genotyping. Results: Genotype frequencies of all tag-SNPs (single nucleotide polymorphisms) showed no association with malaria outcome. However, C allele of rs11203109 was associated with the protection from cerebral malaria (OR=0.62, 95% CI=0.38-0.99, P=0.048). Two single nucleotide polymorphisms (rs5786868 and rs57941432) were in linkage disequilibrium with rs11203109. Conclusions: This suggests that our associated single nucleotide polymorphism (rs11203109) might be a genetic marker of cerebral malaria progression in the Thai population. http://www.apjtm.org/article.asp?issn=1995-7645;year=2018;volume=11;issue=6;spage=376;epage=380;aulast=Wah;type=2.
