Figure 2. Distribution of PNGS in V3, C3 and C4 regions of gp120 in HIV-1 clade C variants obtained during different disease stages.

Figure 2

Table at the bottom reports the frequency of presence of each PNGS. PNGS position in the alignment is according to the HXB2 amino acid sequence numbering. Circles highlight a significant increase of shifting PNGS frequency ES  =  Early disease Stage CS  =  Chronic disease Stage LS  =  Late disease Stage.
