Phenotypic Expression of Heterozygous Lipoprotein Lipase Deficiency
Familial lipoprotein lipase (LPL) deficiency is a rare genetic disorder accompanied by well-characterized manifestations. The phenotypic expression of heterozygous LPL deficiency has not been so clearly defined. We studied the pedigree of a proband known to be homozygous for a mutation resulting in nonfunctional LPL. Hybridization ofDNA from 126 members with allele-specific probes detected 29 c...
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 کاملPrevalence of alleles encoding defective lipoprotein lipase in hypertriglyceridemic patients of French Canadian descent.
It has previously been estimated that due to genetic "founder effects," 97% of lipoprotein lipase (LPL) gene alleles conferring type I hyperlipoproteinemia (HLP) in French Canadians encode one of the following mutant LPL forms: Gly188-->Glu, Pro207-->Leu, or Asp250-->Asn. Although the genetic basis of type I HLP is known to be homozygosity for LPL deficiency, that for other forms of HLP, especi...
متن کاملMutations in the lipoprotein lipase Gene Associated With Ischemic Heart Disease in Men
The aim of this study was to test the hypothesis that the Asp9Asn substitution and the T(293)3G mutation in the promoter of the lipoprotein lipase gene affect plasma lipid levels and thereby the risk of ischemic heart disease (IHD). We genotyped 9033 men and women from a general population sample and 940 patients with IHD. The frequency of both the G allele and the Asn9 allele in the general po...
متن کاملLINGO1 Variants in the French-Canadian Population
Essential tremor (ET) is a complex genetic disorder for which no causative gene has been found. Recently, a genome-wide association study reported that two variants in the LINGO1 locus were associated to this disease. The aim of the present study was to test if this specific association could be replicated using a French-Canadian cohort of 259 ET patients and 479 ethnically matched controls. Ou...
