title: [Distribution of -477C/T single nucleotide polymorphism in the promoter region of ABCA1 gene and its significance for plasma lipids levels in normal Chinese Han population].
abstract: OBJECTIVE
  To investigate the distribution of -477C/T single nucleotide polymorphisms (SNP) in the promoter region of ATP binding cassette transporter (ABCA1) gene and its relation to plasma lipid levels in normal Chinese Han population.
  
  
  METHODS
  The three genotypes of -477C/T polymorphisms in the promoter region of the ABCA1 gene were detected using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 113 normal Chinese Han subjects.
  
  
  RESULTS
  -477C/T SNP was present in normal Chinese Han population, and 37.2% (42) of the examined subjects belonged to the genotype of CC, 46.9% (53) belonged to CT and 15.9% (18) to TT. The individuals with the TT genotype had a lower plasma high-density lipoprotein cholesterol (HDL-C) level than those with the CC genotype (P<0.05). No association was found between the genotypes and plasma levels of total cholesterol, triglyceride, low-density lipoprotein, very low-density lipoprotein and body mass index.
  
  
  CONCLUSIONS
  The TT genotype significantly influences the plasma levels of HDL-C in normal Chinese Han individuals.
