Data are presented as proportions [n (%)] of genetic variants within the study groups. Study participants were categorized into three groups, aparasitemic, SMA (i.e., Hb < 5.0 g/dL with any density parasitemia) or UM (Hb ≥ 5.0 g/dL with any density parasitemia). Statistical significance determined by Fisher’s exact test. Boldface indicates a values of P <0.05.
