Plasmodium falciparum resistance to artemisinin derivatives in southeast Asia threatens malaria control and elimination activities worldwide. To monitor the spread of artemisinin resistance, a molecular marker is urgently needed. Here, using whole-genome sequencing of an artemisinin-resistant parasite line from Africa and clinical parasite isolates from Cambodia, we associate mutations in the PF3D7_1343700 kelch propeller domain ('K13-propeller') with artemisinin resistance in vitro and in vivo. Mutant K13-propeller alleles cluster in Cambodian provinces where resistance is prevalent, and the increasing frequency of a dominant mutant K13-propeller allele correlates with the recent spread of resistance in western Cambodia. Strong correlations between the presence of a mutant allele, in vitro parasite survival rates and in vivo parasite clearance rates indicate that K13-propeller mutations are important determinants of artemisinin resistance. K13-propeller polymorphism constitutes a useful molecular marker for large-scale surveillance efforts to contain artemisinin resistance in the Greater Mekong Subregion and prevent its global spread.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ariey, Frederic -- Witkowski, Benoit -- Amaratunga, Chanaki -- Beghain, Johann -- Langlois, Anne-Claire -- Khim, Nimol -- Kim, Saorin -- Duru, Valentine -- Bouchier, Christiane -- Ma, Laurence -- Lim, Pharath -- Leang, Rithea -- Duong, Socheat -- Sreng, Sokunthea -- Suon, Seila -- Chuor, Char Meng -- Bout, Denis Mey -- Menard, Sandie -- Rogers, William O -- Genton, Blaise -- Fandeur, Thierry -- Miotto, Olivo -- Ringwald, Pascal -- Le Bras, Jacques -- Berry, Antoine -- Barale, Jean-Christophe -- Fairhurst, Rick M -- Benoit-Vical, Francoise -- Mercereau-Puijalon, Odile -- Menard, Didier -- 090770/Z/09/Z/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- G0600718/Medical Research Council/United Kingdom -- Intramural NIH HHS/ -- England -- Nature. 2014 Jan 2;505(7481):50-5. doi: 10.1038/nature12876.
