Mondo Description Familial LCAT (lecithin-cholesterol acyltransferase) deficiency (FLD) is a form of lecithin-cholesterol acyltransferase deficiency (LCAT) characterized clinically by corneal opacities, hemolytic anemia, and renal failure, and biochemically by severely decreased HDL cholesterol and complete deficiency of the LCAT enzyme.

Uniprot Description A disorder of lipoprotein metabolism characterized by inadequate esterification of plasmatic cholesterol. Two clinical forms are recognized: complete LCAT deficiency and fish-eye disease. LCATD is generally referred to the complete form which is associated with absence of both alpha and beta LCAT activities resulting in esterification anomalies involving both HDL (alpha-LCAT activity) and LDL (beta-LCAT activity). It causes a typical triad of diffuse corneal opacities, target cell hemolytic anemia, and proteinuria with renal failure.
