However, the results obtained in this study showed no association betweenthe genes encoding the KIR receptors and their HLA ligands with ZIKV infection.Despite few studies showing an association of KIR genes with otherflaviviruses, Beltrame et al.15and Ramanathan et al.18suggested a possible influence of the KIR2DL5,KIR2DL2 and KIR3DL1 genes on susceptibility todengue infection. This evidence concerns the gene KIR3DL1 and infection.
