Abstract:
OBJECTIVE: To study the genotype distribution of cytochrome CYP3A4, CYP2C9, CYP2C19, CYP2D6 in Han and Mongolian Chinese population and the allele and genotype frequency are compared between the Han and Mongolian. METHODS: CYP3A4, CYP2C9, CYP2C19, CYP2D6 of Han and Mongolian Chinese population were genotyped by PCR-RFLP. RESULTS: The allele frequencies of CYP3A4 * 5 in Han and Mongolian are 0, the allele frequencies of CYP3A4 * 18 in Han and Mongolian are 0.1838, 0.2025. The allele frequencies of CYP2C9 * 2 in Han and Mongolian are 0.0110, 0.0253; the allele frequencies of CYP2C9 * 13 in Han and Mongolian are 0, 0.003 2.The allele frequencies of CYP2C19 * 2 in Han and Mongolian are 0.386 0, 0.4146, the allele frequencies of CYP2C19 * 3 are 0.0515, 0.0443. The allele frequencies of CYP2D6 * 10 in Han and Mongolian are 0.5735, 0.4652. CONCLUSION: The study shows that there are no significant ethnic differences in the distribution of CYP3A4 * 18, CYP2C19 * 2, CYP2C19 * 3, CYP2D6 * 10 genotypes in Han and Mongolian. The CYP3A4 * 5 genotype is not found in this study and only one CYP2C9 * 1/* 13 genotype is found in Mongolian. For CYP2C9 * 2, the Mongolian is significantly lower than the Han, (P=0.023).
