Figure 4. Sequence chromatogram from exon 13 of the TGFBI gene, demonstrating the region around codon 572

The top row of letters represents the wild type nucleotide sequence; codon 572 is designated by the three boxed nucleotides CAC. The bottom row represents the mutated strand, with codon 572 deleted. Shading of both rows highlights the nucleotide sequence 3' of the deleted codon, which is identical on each strand.
