title: [Relationship of APOE gene polymorphism with subclasses of serum high density lipoprotein in hyperlipidemia].
abstract: OBJECTIVE
  To investigate apolipoprotein E(apoE) polymorphism and its relationship with serum lipids and apolipoprotein, serum high density lipoprotein (HDL) subclasses in patients with hyperlipidemia(HL).
  
  
  METHODS
  APOE genotype was assayed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The subclasses of serum HDL in 112 patients with hyperlipidemia and 73 healthy subjects were determined by two-dimensional gel electrophoresis in conjunction with immunodetection method.
  
  
  RESULTS
  APOE3/3 genotypes and allele epsilon3 frequency in HL group and control group were both the highest. In HL group, the genotype of APOE2 had higher serum APOE/CIII ratio and lower HDL3b levels, compared with the genotype of APOE3 (P<0.05). In control group, the genotype of apoE2 had higher serum triglycerides, APOE levels and APOE/CIII ratio, compared with the genotype of APOE3 and APOE4 (P<0.05).
  
  
  CONCLUSIONS
  Polymorphism of APOE gene may relate to the distribution of HDL particles.
