Figure 4: Association plot of subtype B and subtype C.
From: Genotypic Prediction of Co-receptor Tropism of HIV-1 Subtypes A and C
On the x-axis alignment positions of gp120 region are shown for subtype B (left) and C (right), the y-axis represents the associated p-values based on SeqFeatR. Significant differences in amino acid composition between X4 and R5 sequences can be observed at V3 region in both subtypes with the strongest signals. In addition, regions around V1, V2 and V5 show significant differences.
