ABSTRACT
Objective To investigate the distribution frequency of allele genetic polymorphism of drug-metabolizing enzyme CYP2C19?2 (rs4244285) in tumor patients of Han population from Hubei province,to provide guidance for clinical rational drug use related to the genetic polymorphism. Methods CYP2C19?2 genotyping was performed by Fluorescence Dye Terminator Cycle Sequencing System in 285 cancer patients. Genotype frequency and allele frequency were calculated and the genotype distribution in different genders was compared. Compared with the previous studies, we clarified the frequencies of CYP2C19?2 gene polymorphisms in different nationalities. Results All the 285 patients in this study were Han population. The genotype frequency of CYP2C19?2 was 113 (39.6%),138 (48.4%) and 34 (11.9%) for wild-type homozygote (GG), heterozygote (GA) and variant homozygote (AA),respectively.The CYP2C19?2 mutant allele frequency was 36.1%.Genotype distribution of male and female patients did not reach significant difference. Conclusion There is no difference in CYP2C19?2 genotypes distribution among different ethnic groups.
