Overview

Hyperlipidemia can occur as either a primary event or secondary to some underlying disease. The primary hyperlipidemias include chylomicronemia, hypercholesterolemia, dysbetalipoproteinemia, hypertriglyceridemia, mixed hyperlipoproteinemia, and combined hyperlipoproteinemia. Other diseases, such as diabetes mellitus, pancreatitis, renal disease, and hypothyroidism, can cause the secondary form.

Causes

Primary hyperlipidemia

Hyperlipoproteinemia type I

Hyperlipoproteinemia type II

Type IIa
  • Familial hypercholesterolemia
    • Sporadic (due to dietary factors)
    • Polygenic (multiple abnormalities in LDL metabolism)
    • Truly familial (as a result of a mutation in the LDL receptor gene on chromosome 19 (0.2% of the population), the apo B gene (0.2%) or the proprotein convertase subtilisin kexin 9 (PCSK9) gene (very rare))
Type IIb
  • Familial combined hyperlipoproteinemia (FCH)
    • Overproduction of hepatically-derived apo B-100 associated with VLDL
    • Overproduction of substrates, including triglycerides and acetyl-CoA
    • Decreased clearance of LDL

Hyperlipoproteinemia type III

  • Presence of apo E E2/E2 genotype resulting in cholesterol-rich VLDL (β-VLDL)

Hyperlipoproteinemia type IV

  • Familial hypertriglyceridemia
    • Genetic defect, which is passed on in an autosomal dominant fashion

Hyperlipoproteinemia type V

  • Very similar to type I, but with high VLDL in addition to chylomicrons
  • Associated with glucose intolerance and hyperuricemia

Familial lecithin-cholesterol acyltransferase (LCAT) deficiency[1]

  • Caused by mutations of the LCAT gene located on chromosome 16q22, which is passed on in an autosomal recessive fashion
  • Associated with corneal opacities, hemolytic anaemia, and proteinuria

Secondary hyperlipidemia

Secondary to some underlying "non-lipid" etiology
