Figure 2. Schematic diagram shows the position of seven single SNPs in CYP4V2 and haplotypes of 70 patients with the c.802–8_810del17insGC mutation (40 patients in the homozygous state and 30 patients in the heterozygous state). The ancient haplotype is shaded dark blue. Alleles showing recombination from the ancient haplotype are shaded light blue or gray. Alleles beyond the recombination events and not included in the ancient haplotype are not shaded. The number of patients with c.802–8_810del17insGC in the homozygous state (n=homozygous haplotype + heterozygous haplotype).
