Congenital pancreatic lipase deficiency is a rare, monoenzymatic form of exocrine pancreatic failure. All reported patients have presented with similar symptoms and clinical findings, including oily/greasy stools from infancy or early childhood and the absence of discernible pancreatic disease. Failure to thrive has not been observed. Analyses of duodenal contents consistently show a marked decrease of pancreatic lipolytic activity (summary by Figarella et al., 1980). [from OMIM]

Deficiency of lysosomal acid lipase causes 2 distinct phenotypes in humans: Wolman disease (WOLD) and cholesteryl ester storage disease (CESD; 278000). WOLD 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. CESD is a milder, later-onset disorder with primary hepatic involvement by macrophages engorged with cholesteryl esters. This slowly progressive visceral disease has a 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). [from OMIM]

Hepatic lipase deficiency is characterized by premature atherosclerosis, elevated total cholesterol, triglycerides (TG), and very low density lipoprotein (VLDL), as well as TG-rich low density lipoprotein (LDL) and HDL subfractions (summary by Hegele et al., 1991). [from OMIM]
