title: [Relationship between blood lipid level and apolipoprotein E gene polymorphism in offspring from longevity and non-longevity families].
abstract: OBJECTIVE
  To study relationship between genetic factor and level of blood lipid.
  
  
  METHODS
  Levels of blood lipid and difference in apolipoprotein E (apo-E) allele frequencies were compared in 86 offspring in seven Uigur longevity families and 62 offspring in nine Uigur non-longevity families and their relationship was explored.
  
  
  RESULTS
  After adjustment for age and occupation, blood indicators related to atherosclerosis were all lower in the offspring of longevity families than in non-longevity families, and those correlated inversely with it were higher in the former. Blood levels of triglyceride and apo-B were significant lower (P < 0.05) and the ratio of HDL-ch to LDL-ch was significantly higher (P < 0.05) in male offspring of longevity families than of non-longevity families. The ratio of apo-A to apo-B was significantly higher in female offspring of longevity families than of non-longevity families. Frequency of epsilon4 allele also was significantly fewer in the offspring of longevity families than of non-longevity ones (P < 0.01). Also, analysis showed that individuals with epsilon4 allele had higher levels of serum total cholesterol, lower density lipoprotein cholesterol and apo-B than those with other alleles.
  
  
  CONCLUSIONS
  Average level of blood lipid was better in the offspring of longevity families than that of non-longevity families. apo-E allele polymorphism can in part explain its difference.
