Familial 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 کاملVariable expression of the mutation in familial defective apolipoprotein B-100.
Although most subjects with familial defective apolipoprotein B-100 (FDB) have raised plasma low-density lipoprotein (LDL) levels, a few have LDL levels within the normal range. We have previously identified two normocholesterolemic FDB heterozygotes in an affected family. Results obtained from a study of this family are compatible with a major genetic contribution to the normocholesterolemia i...
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...

familial defective apolipoprotein (apo) b 100 (fdb) causes early-onset coronary heart diseases (chd). it is produced by r3500q mutation of the apob gene resulting in decreased binding of ldl to ldl receptor. we screened the apo b gene for r3500q mutation in 130 hypercholesterolemic patients, among whom 30 patients met criteria of familial hypercholesterolemia (fh). the prevalence of r3500q alle...
