While type 1 hyperlipidemia is associated with lipoprotein lipase or apoCII deficiencies, the etiology of type 5 hyperlipidemia remains largely unknown. We explored a new candidate gene, APOA5, for possible causative mutations in a pedigree of late-onset, vertically transmitted hyperchylomicronemia. A heterozygous Q139X mutation in APOA5 was present in both the proband and his affected son but ...
Lipoprotein lipase (LPL) and hepatic triglyceride lipase (HTGL) enhance the hydrolysis of triglycerides (TG) transported by chylomicron (CM) and very-low-density lipoprotein (VLDL). We report a case of severe hyperchylomicronemia with high levels of remnant lipoprotein and total cholesterol (T-Chol) in a 15-year-old boy. Precise examination of the lipid profile showed decreased activities of bo...
The molecular defects resulting in a deficiency of lipoprotein lipase activity in a patient with the familial hyperchylomicronemia syndrome have been identified. Increased lipoprotein lipase mass but undetectable lipoprotein lipase activity in the patient's post-heparin plasma indicate the presence of an inactive enzyme. No major gene rearrangements were identified by Southern blot analysis of ...
Familial chylomicronemia syndrome is a group of rare genetic disorders characterized by deficient activity of an enzyme lipoprotein lipase or apo-protein C-II deficiency. In this paper we present an infant with massive hyperchylomicronemia and severe pancreatitis. Exchange transfusion for controlling hypertriglyceridemia and pancreatitis led to an increase in hyperviscosity which resulted in en...
There are no adequate data that evaluate the safety and effectiveness of lowering triglyceride levels in very young children. The authors report a family with two male siblings, 7 and 4 years old, affected by familial hyperchylomicronemia. The oldest was diagnosed at birth during evaluation of jaundice, and the youngest showed asymptomatic hypertriglyceridemia by 6 months of age. Due to high tr...
Recent studies on diabetes and metabolic syndrome indicate a common disturbance of inorganic phosphate (Pi) metabolism. Pi is an important substrate in the formation of adenosine triphosphate (ATP), and many lifestyle diseases and cardiovascular risk factors similarly show deficiencies in either 1 or 2 major components of ATP synthesis. Age, male gender, hypertension, obesity, hypertriglyceride...
