Objective To investigate the gene polymorphisms of CYP1A1*2C in Chinese Miao, Buyi nationalities.
Methods Taqman-MGB probe was used in real-time RealTime-PCR to test the polymorphisms of CYP1A1*2C in Chinese Miao(125), Buyi(122)people, and the significant difference between Miao and Buyi was checked by χ2 test.
Results The distribution of wild homozygote(genetic type AA), mutant heterozygote(genetic type AG), mutant homozygote(genetic type GG)of CYP1A1*2C in Chinese Miao, Buyi populations were 65.6%, 28.0%, 6.4% and 68.9%, 25.4%, 5.7%, respectively. The distribution of A and G allele frequency of CYP1A1*2C in Miao, Buyi populations were 79.6%, 20.4% and 81.6%, 18.4%, respectively.
Conclusion The distribution of genetic frequency and allele gene frequency of CYP1A1*2CC are without statistically significance in difference between Miao, Buyi nationalities in Guizhou Province China.
