Figure 1. Schematic showing IL28 genes, SNP locations and areas of sequence homology.

Figure 1

Illustration of the relative locations of the IL28A and IL28B genes on the forward and reverse DNA strands on chromosome 19. The shaded boxes indicate regions of the inverted duplication with >95% sequence identity. The direction of the shaded gradient indicates the orientation of the match. SNP identifiers in blue were unique to the IL28B region, whereas SNPs highlighted in other colors were present in the IL28B region as well as a corresponding region in IL28A.
