KIR3DL1 and malaria: An interesting observation was that none of the 14 children with CM+SRD, considered to be the most critically ill patients, was homozygous for KIR genotype A, while a substantial proportion of children with less severe forms of malaria were homozygous for genotype A (11%, 16%, 18% and 26% in UM, SP, SA and CM, respectively).
