FIG 2 Identification of CYP2C19 * 2/3/17 polymorphism loci. A. CYP2C19 * 2 wild-type and mutant. B. CYP2C19 * 2/3 heterozygosity. C. CYP2C19 * 3 wild-type and mutant. D. CYP2C19 * 2/17 heterozygosity. E. CYP2C19 * 17 wild-type and mutant. F. CYP2C19 * 3/17 heterozygosity. G. CYP2C19 * 2/3/17 heterozygosity. W, wild-type; M, mutant; -dF/dt, negative derivative of fluorescence over temperature; NTC, negative control.
