Flow cytometric assessment of LDL ligand function for detection of heterozygous familial defective apolipoprotein B-100.
BACKGROUND Familial defective apolipoprotein (apo) B-100 (FDB) is caused by a mutation in the apoB gene and characterized by decreased binding of LDL to LDL receptors because of reduced function of the apoB-100 ligand. FDB may be associated with severe hypercholesterolemia and cannot always be distinguished from familial hypercholesterolemia phenotypically. METHODS We used a fluorescence flow...
متن کاملHigh prevalence of familial defective apolipoprotein B-100 in Switzerland.
Familial defective apolipoprotein B-100 (FDB) is caused by a single G-to-A substitution at nucleotide 10,708 leading to an arginine to glutamine change at amino acid 3,500 of the apolipoprotein B-100 and thus, a reduced binding of the apolipoprotein B to the low density lipoprotein (LDL) receptor. In the present study, the prevalence of FDB in Switzerland was estimated, on the one hand, from a ...
متن کاملRapid diagnosis of familial defective apolipoprotein B-100.
A method is described for the rapid, economic and non-radioactive examination of DNA samples from hypercholesterolaemic patients for familial defective apolipoprotein B-100, using a modified polymerase chain reaction (PCR) protocol and restriction enzyme isoform genotyping. Because of the high prevalence of familial defective apolipoprotein B-100, which is estimated to be one in 500 in most scr...
متن کاملFamilial defective apolipoprotein B-100: a mutation of apolipoprotein B that causes hypercholesterolemia.
Familial defective apolipoprotein B-100 is a genetic disorder of apolipoprotein B-100 that causes moderate to severe hypercholesterolemia. A single amino acid mutation in apolipoprotein B diminishes the ability of low density lipoproteins to bind to the low density lipoprotein receptor. Low density lipoproteins accumulate in the plasma because their efficient receptor-mediated catabolism is dis...
متن کاملCompound heterozygous familial hypercholesterolemia and familial defective apolipoprotein B-100 produce exaggerated hypercholesterolemia.
BACKGROUND Familial hypercholesterolemia (FH) and familial defective apolipoprotein B-100 (FDB) represent ligand-receptor disorders that are complementary. Individuals with both FH and FDB are unusual. We report a family with both disorders and the impact of the mutations on the phenotypes of the family members. METHODS We used single strand conformation polymorphism (SSCP) and denaturing gra...
