Figure 1. Representation of the domains within the VZV immediate early regulatory protein IE62.
VZV ORF62 contains a high number of SNPs, as shown in Table 1. Therefore, this ORF has played an important role in early phylogenetic analysis of VZV strains (Faga et al, 2001). Two SNPs within ORF62 that may be involved in the VZV attenuation genotype are shown in bold type in the center of the figure.
