Familial chylomicronemia (type I hyperlipoproteinemia) due to a single missense mutation in the lipoprotein lipase gene.
Complete deficiency of lipoprotein lipase (LPL) causes the chylomicronemia syndrome. To understand the molecular basis of LPL deficiency, two siblings with drastically reduced postheparin plasma lipolytic activities were selected for analysis of their LPL gene. We used the polymerase chain reaction to examine the nine coding LPL exons in the two affected siblings and three relatives. DNA sequen...
متن کاملMolecular basis of familial chylomicronemia: mutations in the lipoprotein lipase and apolipoprotein C-II genes.
The molecular basis of familial chylomicronemia (type I hyperlipoproteinemia), a rare autosomal recessive trait, was investigated in six unrelated individuals (five of Spanish descent and one of Northern European extraction). DNA amplification by polymerase chain reaction (PCR) followed by single strand conformation polymorphism (SSCP) analysis allowed rapid identification of the underlying mut...
متن کاملA missense (Asp250----Asn) mutation in the lipoprotein lipase gene in two unrelated families with familial lipoprotein lipase deficiency.
We have identified the molecular basis for familial lipoprotein lipase (LPL) deficiency in two unrelated families with the syndrome of familial hyperchylomicronemia. All 10 exons of the LPL gene were amplified from the two probands' genomic DNA by polymerase chain reaction. In family 1 of French descent, direct sequencing of the amplification products revealed that the patient was heterozygous ...
متن کاملFamilial Hypercholesterolemia in Iran: A Novel Frameshift Mutation in Low Density Lipoprotein Receptor (LDLR) Gene
Background and Objective: Familial hypercholesterolemia (FH) is an autosomal trait, which is caused by mutations in Low Density Lipoprotein Receptor (LDLR) gene. FH penetrance is about 100% and worldwide prevalence for heterozygous subjects is almost 1 in 500 and for homozygous 1 in 1,000,000. The patients are at risk of premature coronary heart disease (CHD) due to defective LDLR a...
متن کاملLipoprotein Lipase (LPL) Gene Mutation: A First Report in Children
Genetic hyperchylomicronemia is a rare autosomal recessive disorder of lipoprotein metabolism estimated to affect approximately one per million individuals. We report a case with a rare mutation identified. It’s a genetic chylomicronemia in a Moroccan newborn baby, with massive hypertriglyceridemia and clinical signs of acute pancreatitis. She was a newborn female, first-degree of consanguineou...
