A rare lipoprotein metabolism disorder characterised clinically by corneal opacities and sometimes renal failure and haemolytic anaemia, and biochemically by severely reduced HDL cholesterol. Age of onset is variable but most patients are diagnosed during adulthood. Two familial forms of LCAT deficiency have been reported: familial LCAT deficiency characterised by corneal opacities, anaemia and renal insufficiency and Fish-eye disease characterised by corneal opacities and sometimes atherosclerosis. LCAT deficiency is caused by deficient or absent catalytic activity of the LCAT enzyme, which catalyses the formation of cholesterol esters in lipoproteins and is encoded by the LCAT gene (16q22.1). Accumulation of unesterified cholesterol in the body for example in the cornea, erythrocytes and kidneys, is thought to underlie the clinical manifestations.

A form of genetic LCAT (lecithin-cholesterol acyltransferase) deficiency characterised clinically by corneal opacifications, and biochemically by significantly reduced HDL cholesterol and partial LCAT enzyme deficiency. The disease is very rare. Corneal opacities are progressive and are observed from an early age (adolescence or young adulthood) and sometimes result in visual impairment. These lesions are generally more severe than in complete LCAT deficiency and form a mosaic pattern of small dot-like grey-white opacities. Signs of atherosclerosis have only been reported in rare cases although patients have low HDL cholesterol levels. In patients with this disorder, alpha-LCAT activity is abolished, but beta-LCAT activity is preserved. Impaired enzyme function is thought to result in deposition of lipids in the cornea. The disease follows an autosomal recessive pattern of inheritance.	Associated morphology	True	Opacity	Inferred relationship	Some	2
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. Age of onset and severity of clinical manifestations are variable. Caused by mutations in the LCAT gene (16q22.1) encoding the LCAT enzyme which catalyzes the formation of cholesterol esters in lipoproteins, leading to progressive lipid deposition in body tissues. There is no clear genotype-phenotype correlation since family members with the same mutation have been found to have different clinical and biochemical pictures. Environmental factors or other minor genes may therefore also be involved in the disorder.	Associated morphology	True	Opacity	Inferred relationship	Some	1
