Table 3 Association between polymorphims in pfmdr 1 and 5 putative transporter genes and chloroquine response phenotype and pfcrt 76 mutant allele of 27 P. falciparum isolates.

From: Lack of association between putative transporter gene polymorphisms in Plasmodium falciparum and chloroquine resistance in imported malaria isolates from Africa

  1. aFifty percent inhibitory concentration values : resistance value to chloroquine (CQ) corresponds to IC50 > 100 nM
  2. NA for not applicable : no SNP was found in the studied isolates and the reference strains
