3.11.5 MOLECULAR MARKERS FOR ANTI-MALARIAL DRUG RESISTANCE Currently there are no clear molecular markers associated with decreased susceptibility to ACTs. Therefore we do not anticipate at this moment to study molecular markers of ACT resistance. However a region of chromosome 13 on the P. falciparum genome that is linked to decreased parasite clearance rates in response to ACTs has been identified28. If putative markers of artemisinin resistance are identified in the next 5 years the FTA cards from this study should be made available to the World Wide Antimalarial Resistance Network (WWARN) for analysis. Permission to store the FTA cards at -70⁰C at the Amsterdam Medical Centre, The Netherlands for 5 years after termination of the study, and their use for determination of molecular markers of resistance will therefore be requested in the informed consent forms.
