High triglyceride levels, a risk factor for cardiovascular disease, are influenced by the apoAV gene. Specific apoAV variants are linked to elevated triglycerides and potentially heart attack risk.

Area of Science:

  • Genetics
  • Cardiovascular Medicine
  • Biochemistry

Background:

  • High plasma triglyceride levels are a significant risk factor for cardiovascular disease (CVD), a leading cause of death globally.
  • Plasma triglyceride levels are known to be influenced by genetic factors, with the apoAV gene playing a crucial role.
  • Over ten variants of the human apoAV gene have been identified, with several extensively studied for their association with triglyceride levels.

Purpose of the Study:

  • To investigate the association between specific apoAV gene variants and plasma triglyceride levels.
  • To explore the potential impact of these variants on cardiovascular disease risk factors, such as myocardial infarction and LDL particle size.
  • To examine the relationship between the Val153-->Met polymorphism and plasma HDL cholesterol levels in females.

Main Methods:

  • Analysis of population studies to identify associations between apoAV gene variants and plasma triglyceride levels.
  • Investigation of specific variants: T-1131-->C, Ser19-->Trp, Val153-->Met, and Cys185-->Gly.
  • Assessment of the influence of these variants on myocardial infarction risk and LDL particle size.

Main Results:

  • Alleles C-1131, Trp19, and Cys185 (found in Chinese populations) are associated with elevated plasma triglyceride levels.
  • The T-1131-->C and Ser19-->Trp apoAV variants may influence myocardial infarction risk and LDL particle size.
  • The Val153-->Met polymorphism is not directly associated with plasma triglyceride levels, but homozygous females show elevated HDL cholesterol.

Conclusions:

  • The apoAV gene and its variants are significant determinants of plasma triglyceride levels.
  • Certain apoAV variants are linked to increased cardiovascular disease risk factors.
  • Further research is warranted to fully elucidate the role of apoAV gene variants in cardiovascular health across diverse populations.
