RNA from 20 gametocytemic patients was analyzed using a P. falciparum whole genome microarray. The color coded cluster analysis of the quantile normalized expression data for the Pfge genes with a G+/Gdef ratio>10 is shown with mature gametocyte specific genes Pfs25 and Pfs28 (Underlined in gray). The gene name and standardized intensity of the color code is indicated below and the patient cluster associated with high gametocytemia is indicated on the right with a vertical green bar. The gametocytemia (G'cyte) and asexual parasitemia (Asex) of the patient samples are represented both by color code and numerically on the right.
