title: [Polymorphism of CYP1A1 gene Msp I site in the Mongolian and Han nationality populations of Inner Mongolia of China].
abstract: OBJECTIVE
  To study the polymorphism of CYP1A1 gene Msp I site in the Mongolian and Han nationality populations of Inner Mongolia.
  
  
  METHODS
  The PCR-restriction fragment length polymorphism(PCR-RFLP) technique was used to analyze the genotypes of CYP1A1 gene Msp I site in 80 subjects of Mongolian nationality and 120 subjects of Han nationality among whom there is no blood relationship each other.
  
  
  RESULTS
  The genotype frequency of CYP1A1 gene Msp I site showed that the wild-type, heterozygote, homozygous variants were 35.0%, 48.7%, 16.3% and 33.3%, 52.5%, 14.2% respectively distributions of Mongolian nationality and Han nationality population, and the Chi-square tests showed that there was no significant difference between the two groups.
  
  
  CONCLUSIONS
  The genotype frequency distributions of CYP1A1 gene Msp I site did not exhibit the obvious difference between Mongolian nationality and Han nationality population of Inner Mongolia.
