Study identifies drug resistance loci in Plasmodium falciparum
Using a combination of sequence-based genome-wide association studies (GWAS) and in vitro selection tests, researchers have detected several loci associated with antimalarial resistance in Plasmodium falciparum. While some loci represent known signals — pfcrt, dhfr, and pfmdr1 — many of the genes were not previously implicated in resistance.
The findings, based on the analysis of data from 45 Senegalese parasites, were reported in the Proceedings of the National Academy of Sciences.
