Figure 1. Location of the FZD4 amplimers

Schematic diagram of the FZD4 gene showing the locations of the amplimers used in this study. The exons are represented by blocks, introns by lines and UTR's by dashed lines. The bars above the gene represent the PCR products. Exon 1 was amplified in one segment. Exon 2 was amplified in five overlapping segments due to its large size.
