OBJECTIVE To investigate the contribution of polymorphisms in multiple candidate genes to cardiovascular disease (CVD) risk in a large cohort of patients with heterozygous familial hypercholesterolemia (FH). METHODS AND RESULTS We genotyped 1940 FH patients for 65 polymorphisms in 36 candidate genes. During 91.451 person-years, 643 (33.1%) patients had at least 1 cardiovascular event. Multifa...

BACKGROUND AND AIMS We recently identified lysosomal acid lipase (LAL) deficiency, a recessive disease caused by mutations in LIPA, in 3 patients with a clinical diagnosis of familial hypercholesterolemia (FH). We aimed to determine the prevalence of LIPA mutations among individuals with a clinical FH diagnosis. METHODS In 276 patients with phenotypic FH, in whom no genetic basis for their ph...

Pregnancy in women with homozygous familial hypercholesterolemia (FH) has been rarely reported and might pose risks on the mother and her fetus. Although most reported cases remained on low-density lipoprotein (LDL) apheresis, there are no clear guidelines regarding the management of this entity. We report the first case of an uncomplicated pregnancy in a 24-year-old homozygous FH woman who was...

Low density lipoprotein (LDL) metabolism was investigated using a pulse injection of 125I-labeled LDL in 20 subjects who did not have familial hypercholesterolemia (FH) (plasma cholesterol 160-297 mg/dl) and in 9 subjects who did have heterozygous FH (plasma cholesterol 273-501 mg/dl). Subjects were also injected with 131I-labeled LDL chemically modified with cyclohexanedione. This technique pe...

Background Familial hypercholesterolemia (FH) is a disorder that is inherited by autosomal dominant pattern. The main cause of FH disease is the occurrence of mutations in low-density lipoprotein receptor (LDLR) gene sequence, as well as apolipoprotein B and proprotein convertase subtilisin/kexin type 9 genes, located in the next ranks, respectively. Materials and Methods Forty-five unrelated...

BACKGROUND AND PURPOSE To correlate known vascular disease risk factors and the signs of extracranial and intracranial changes of vascular origin in young patients with heterozygous familial hypercholesterolemia (FH). METHODS 39 DNA test-verified heterozygous FH North Karelian patients (FH-NK), aged 6 to 48, 28 of them treated with statins, and 25 healthy controls underwent brain magnetic res...

The low-density lipoprotein receptor (LDLr) plays a pivotal role in cholesterol homeostasis. Mutations in the LDLr gene (LDLR), which is located on chromosome 19, cause familial hypercholesterolemia (FH), an autosomal dominant disorder characterized by severe hypercholesterolemia associated with premature coronary atherosclerosis. To date almost 300 mutations have been identified in the LDLR ge...

Autosomal recessive hypercholesterolemia (ARH) is a genetic form of hypercholesterolemia that clinically resembles familial hypercholesterolemia (FH). As in FH, the rate of clearance of circulating low density lipoprotein (LDL) by the LDL receptor (LDLR) in the liver is markedly reduced in ARH. Unlike FH, LDL uptake in cultured fibroblasts from ARH patients is normal or only slightly impaired. ...

Probucol has been shown to be an effective and well-tolerated cholesterol-lowering drug. However, response in terms of cholesterol reduction has been shown to vary significantly among individuals. The purpose of this study was to assess the role of apolipoprotein E polymorphism in determining this variation. A retrospective study of 89 hypercholesterolemic type II patients who had been treated ...
