Description : 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 discernable 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).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the pancreatic lipase gene (PNLIP, 246600.0001);
Laboratory abnormalities : Low pancreatic lipase levels; Low fecal elastase levels (in some patients); Low or low-normal levels of fat-soluble vitamins; Abnormal pancreolauryl test (in some patients); Hypolipidemia (in some patients);
