摘要: 为探讨中国人与吸烟致癌力有关的细胞色素P4501A1(cytochrome P4501A1,CYP1A1)基因催化部位(外显子7)的多态性分布情况,分析了458例中国人CYP1A1基因外显子7的多态性分布频率.结果显示这种多态性在男女之间没有显着差异,458例中国人该基因不同类型的比例分别为Ile/Ile61.6%、Ile/Val26.4%、Val/Val12.0%,其中Val/Val基因型所占的比例显着高于日本人、白种人或非洲美国人.

Abstract: P4501A1 is a kind of enzyme related with the carcinogenic activity of aromatic hydrocarbon, the polymorphism in exons 7 of the gene could alter the function, and has been reported to be associated with lung cancer in Japanese. But data from Caucasian or African-American were different. The difference is said to be from the different frequencies of this polymorphism between ethnic groups. This paper analyzed the frequency of polymorphism in exons 7 of CYP1A1 gene in Chinese by the PCR method. The results suggested that the frequencies of genotype in Chinese were Ile/Ile 61.6%, Ile/Val 26.4% and Val/Val 12.0%, no significant difference of the frequencies between male and female was found. But the frequency of Val/Val was much higher than that in Japanese, Caucasian or African American.
