Definition / general
  • Lecithin cholesterol acyltransferase (LCAT) is crucial to maturation of high density lipoprotein (HDL)
  • Homozygosity causes deficiency of HDL cholesterol (HDL-c); heterozygotes have half normal HDL-c levels
  • Usually but not always due to mutations in coding sequence (Hum Mutat 2011;32:1290, Clin Nephrol 2011;76:323)
  • Associated with nephrotic syndrome
Case reports
  • Two brothers with nephrotic syndrome and lecithin cholesterol acyltransferase deficiency (Mod Pathol 1991;4:331)
Treatment
Microscopic (histologic) description
  • Bubbly thickening of glomerular basement membrane in membranous pattern; mesangial sclerosis and foamy macrophages in capillaries and mesangium
Electron microscopy description
  • Small, solid, thread like or lamellar dense structures in empty appearing lacunae
