Figure 1: DNA sequence chromatograms (IMAGE) Tokyo Metropolitan Institute of Medical Science Caption Novel variants (blue arrows), variants in coding regions (V1–V4 variants: red arrows), and others (black arrows) are shown. Heterozygous sequence traces derived from individuals carrying (A) a cytosine deletion within exon 5 (V1 variant) and (B) a mutation from guanine to adenine at the first position of exon 8 (V3 variant).
