" /> Cholesteryl ester storage disease - CISMeF





Preferred Label : Cholesteryl ester storage disease;

Symbol : CESD;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Cholesterol ester hydrolase deficiency, partial; Lipa deficiency, partial; Lal deficiency, partial; Lysosomal acid lipase deficiency, partial;

Description : Deficiency of lysosomal acid lipase causes 2 distinct phenotypes in humans: Wolman disease and cholesteryl ester storage disease (CESD). Wolman disease is an early-onset fulminant disorder of infancy with massive infiltration of the liver, spleen, and other organs by macrophages filled with cholesteryl esters and triglycerides. Death occurs early in life. Wolman disease is very rare, with an incidence of less than one in 100,000 live births. CESD is a milder, later-onset disorder with primary hepatic involvement by macrophages engorged with cholesteryl esters. This slowly progressive visceral disease has a very wide spectrum of involvement ranging from early onset with severe cirrhosis to later onset of more slowly progressive hepatic disease with survival into adulthood (summary by Du et al., 2001).;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the lysosomal acid lipase gene (LIPA, 613497.0001);

Laboratory abnormalities : Elevated alanine aminotransferase (ALT); Hypercholesterolemia; Hypertriglyceridemia; Low lysosomal acid lipase activity;

Prefixed ID : #278000;
