title: [Study on the association of cholesteryl ester transfer protein gene mutations with the susceptibility to coronary atherosclerotic heart disease].
abstract: OBJECTIVE
  To determine the frequencies of 4 mutations of cholesteryl ester transfer protein (CETP) gene in Chinese population and to investigate the association of the mutations with lipid metabolism and the susceptibility to coronary atherosclerotic heart disease (CHD).
  
  
  METHODS
  The target fragments of CETP gene were amplified and analyzed by PCR-restriction fragment length polymorphism technique in 209 unrelated control individuals and 203 CHD patients. The test for Hardy-Weinberg equilibrium was performed using HWE program and statistical analysis was implemented in statistical package SPSS.
  
  
  RESULTS
  IVS14A and 451Q mutant genes were not found in either control group or patient group. The frequencies of 405V mutant allele were 0.443 and 0.413 in controls and patients, respectively, while 442G mutant gene frequencies were 0.007 and 0.025, respectively. The observed allele frequencies of I405V and D442G mutation were in accord with Hardy-Weinberg equilibrium. The frequency of 442G mutant gene in patients was significantly higher than that in controls (P=0.043). Compared with the CHD patients without D442G mutation, the 442G heterozygous CHD patients exhibited a significant increase in plasma TC and LDL-C concentration (P=0.017; P=0.041).
  
  
  CONCLUSIONS
  IVS14A and 451Q mutants of CETP gene were rare in Chinese population and 442G mutant gene was possibly one of the susceptibility factors to CHD in Chinese.
