Disease Class: Malaria [ICD-11: 1F45.0] [1]

• Resistant Disease: Malaria [ICD-11: 1F45.0]
• Resistant Drug: Quinine
• Molecule Alteration: Missense mutation + Chromosome variation; ms4760+ 3 DNNND repeats
• Experimental Note: Discovered Using In-vivo Testing Model
• In Vitro Model: Plasmodium falciparum strains; 5833
• Experiment for Molecule Alteration: Genotypic characterization assay
• Experiment for Drug Resistance: SYBR Green I detection assay
• Mechanism Description: Eighty-two percent of parasites resistant to quinine carried mutant alleles at these codons (Pfmdr1-86Y, Pfmdr1-184F, and Pfcrt-76T), whereas 74% of parasites susceptible to quinine carried the wild-type allele (Pfmdr1-N86, Pfmdr1-Y184, and Pfcrt-k76, respect.
