Lipoprotein 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...
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 کاملHeterogeneous mutations in the human lipoprotein lipase gene in patients with familial lipoprotein lipase deficiency.
The DNA sequences were determined for the lipoprotein lipase (LPL) gene from five unrelated Japanese patients with familial LPL deficiency. The results demonstrated that all five patients are homozygotes for distinct point mutations dispersed throughout the LPL gene. Patient 1 has a G-to-A transition at the first nucleotide of intron 2, which abolishes normal splicing. Patient 2 has a nonsense ...
متن کاملHeterozygous lipoprotein lipase deficiency due to a missense mutation as the cause of impaired triglyceride tolerance with multiple lipoprotein abnormalities.
In 16 members of two Austrian families affected by a missense mutation at codon 188 of the lipoprotein lipase (LPL) gene (8 heterozygous and 8 normal subjects), carrier status for the mutation as determined by DNA analysis was related to LPL activity in postheparin plasma, to the magnitude of postprandial lipemia, and to concentration, composition, and size of the major lipoprotein classes of p...
متن کاملFamilial 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...
