Abstract: To investigate the association of CYP3A5*3 with Acute Lymphoblastic Leukemia (ALL) susceptiveness in Chinese Han children.METHODS: CYP3A5 genotype was analyzed from 172 Chinese han children, including 52 ALL patients(27 female and 25 male) and 120 healthy controls(80 female and 92 male).Genomic DNA was extracted from blood sample, and PCR-RFLP was used to identify the polymorphism.RESULTS: This polymorphism were matched to Hardy-Weinberg equilibrium in all group.The allelic frequency of CYP3A5*3 was 0.721 (95% CI: 0.549, 0.893) in patients while 0.758 (95% CI: 0.674, 0.842) in healthy controls. There was no significant difference existed in CYP3A5*3 frequencies between patients and controls (P=0.275), males and females (P=0.432) in the total population.CONCLUSION: The CYP3A5*3 variant represents a common polymorphism in Chinese healthy children and ALL, and this polymorphism is poor association with ALL susceptiveness in children.
