Our study confirms earlier findings showing that mutations of LCAT may result in widely different clinical phenotypes (for review, see Reference 88 ) and specifically describes two mutant LCAT varieties that are associated with unique lipoprotein abnormalities. In addition, we report for the first time the occurrence of a similar mutant LCAT gene in a substantial percentage of subjects with hypoalphalipoproteinemia.. Both the Gly230Arg (LCATFin) and the Arg399Cys point mutations affect exon 6, encoding almost half of the LCAT enzyme.18 The active site of LCAT, based on homology studies with other serine-dependent esterases28 and site-directed mutagenesis analysis of LCAT,29 is postulated to be located around Ser181. No mutations affecting the proposed functional area itself have been reported thus far. The LCATFin mutation, involving a substitution of a positively charged amino acid for a nonpolar amino acid, is localized to an area of the LCAT protein whose function is poorly understood. The ...

Lecithin:cholesterol acyltransferase (LCAT) catalyzes plasma cholesteryl ester formation and is defective in familial lecithin:cholesterol acyltransferase deficiency (FLD), an autosomal recessive disorder characterized by low high-density lipoprotein, anemia, and renal disease. This study aimed to investigate the mechanism by which compound A [3-(5-(ethylthio)-1,3,4-thiadiazol-2-ylthio)pyrazine-2-carbonitrile], a small heterocyclic amine, activates LCAT. The effect of compound A on LCAT was tested in human plasma and with recombinant LCAT. Mass spectrometry and nuclear magnetic resonance were used to determine compound A adduct formation with LCAT. Molecular modeling was performed to gain insight into the effects of compound A on LCAT structure and activity. Compound A increased LCAT activity in a subset (three of nine) of LCAT mutations to levels comparable to FLD heterozygotes. The site-directed mutation LCAT-Cys31Gly prevented activation by compound A. Substitution of Cys31 with charged ...

Lecithin cholesterol acyltransferase deficiency (LCAT deficiency) is a disorder of lipoprotein metabolism. The disease has two forms: Familial LCAT deficiency, in which there is complete LCAT deficiency, and Fish-eye disease, in which there is a partial deficiency. Lecithin cholesterol acyltransferase catalyzes the formation of cholesterol esters in lipoproteins. Symptoms of the familial form include visual impairment caused by diffuse corneal opacities, target cell hemolytic anemia, and renal failure. Less common symptoms include atherosclerosis, hepatomegaly (enlarged liver), splenomegaly (enlarged spleen), and lymphadenopathy. Fish-eye disease is less severe and most commonly presents with impaired vision due to corneal opacification. It rarely presents with other findings, although, atherosclerosis, hepatomegaly, splenomegaly, and lymphadenopathy can occur. Carlson and Philipson found that the disease was named so because the cornea of the eye was so opaque or cloudy with dots of cholesterol ...

Background: Whole exome sequencing (WES) has shown ~30% success in the diagnosis of Mendelian disorders. Few data exists regarding clinical application of WES for the molecular diagnosis of familial hypobetalipoproteinemia (FHBL), which is characterized as extremely low LDL cholesterol level.. Methods: WES was performed on 36 individuals including 32 patients exhibiting low LDL-C (less than 70 mg/dl) primarily, and 4 unaffected family members from 23 families. We filtered out the following variants: 1) Benign variants predicted by SnpEff; 2) Minor allele frequency (MAF) , 1%; 3) Segregation unmatched for the autosomal codominant pattern; 4) C-score , 10 calculated using in silico prediction software named Combined Annotation Dependent Depletion.. Results: Among 181,404 variants found in those individuals, we found 48,786 nonsense, missense, or splice site variants, of which 14,415 were rare (MAF ≤ 1% or not reported). Filtering assuming autosomal codominant pattern of inheritance combined with ...

This gene product is the main apolipoprotein of chylomicrons and low density lipoproteins. It occurs in plasma as two main isoforms, apoB-48 and apoB-100: the former is synthesized exclusively in the gut and the latter in the liver. The intestinal and the hepatic forms of apoB are encoded by a single gene from a single, very long mRNA. The two isoforms share a common N-terminal sequence. The shorter apoB-48 protein is produced after RNA editing of the apoB-100 transcript at residue 2180 (CAA->UAA), resulting in the creation of a stop codon, and early translation termination. Mutations in this gene or its regulatory region cause hypobetalipoproteinemia, normotriglyceridemic hypobetalipoproteinemia, and hypercholesterolemia due to ligand-defective apoB, diseases affecting plasma cholesterol and apoB levels.

We have identified a novel point mutation of the apo A-I gene, designated as apo A-IFin, causing dominantly inherited hypoalphalipoproteinemia in 7 individuals of a 15-member kindred with severely diminished serum HDL-C and apo A-I concentrations. The mutation, a single T-to-G substitution in exon 4 at position 2024, substitutes arginine for leucine at residue 159 of the mature apo A-I protein and has a profound effect on serum HDL-C and apo A-I levels. On genotyping of the family members by a PCR-based restriction typing analysis, all affected subjects were found to be heterozygous for the apo A-IFin mutation, while the nonaffected members had the wild-type sequence.. Isoelectric focusing of serum and HDL samples of affected subjects revealed that the mutant protein is expressed and secreted in vivo, together with the normal apo A-I, and is present in both serum and HDL of mutation carriers (Fig 2⇑). Immunoblotting studies of samples of the affected subjects showed that the intensities of the ...

Fish-eye disease is caused by mutations in the LCAT gene. This gene provides instructions for making an enzyme called lecithin-cholesterol acyltransferase (LCAT).. The LCAT enzyme plays a role in removing cholesterol from the blood and tissues by helping it attach to molecules called lipoproteins, which carry it to the liver. Once in the liver, the cholesterol is redistributed to other tissues or removed from the body. The enzyme has two major functions, called alpha- and beta-LCAT activity. Alpha-LCAT activity helps attach cholesterol to a lipoprotein called high-density lipoprotein (HDL). Beta-LCAT activity helps attach cholesterol to other lipoproteins called very low-density lipoprotein (VLDL) and low-density lipoprotein (LDL).. LCAT gene mutations that cause fish-eye disease impair alpha-LCAT activity, reducing the enzymes ability to attach cholesterol to HDL. Impairment of this mechanism for reducing cholesterol in the body leads to cholesterol-containing opacities in the corneas. It is ...

TY - JOUR. T1 - Adrenal function in heterozygous and homozygous hypobetalipoproteinemia. AU - Illingworth, D. Roger. AU - Kenny, Terry A.. AU - Orwoll, Eric. PY - 1982. Y1 - 1982. N2 - Corticosteroid synthesis in the human adrenal cortex requires a supply of cholesterol which can be derived from both local synthesis and the uptake of plasma lipoproteins. Studies with cultured adrenal cells have shown that such uptake i s mediated through the interaction of plasma low density lipo-proteins (LDL) and a specific cellular receptor (the LDL receptor). In the present study we have examined parameters of adrenal corticosteroid production in a patient with phenotypic abetalipoproteinemia (on the basis of homozygous hypobetalip-oproteinemia) and in three of her relatives with inherently low levels of LDL (heterozygous hypobetalipoproteinemia). These studies sought to determine whether the absence of LDL or an inherent reduction in their plasma concentration results in alterations in corticosteroid ...

Complete LCAT deficiency is a disorder that primarily affects the eyes and kidneys.. In complete LCAT deficiency, the clear front surface of the eyes (the corneas) gradually becomes cloudy. The cloudiness, which generally first appears in early childhood, consists of small grayish dots of cholesterol (opacities) distributed across the corneas. Cholesterol is a waxy, fat-like substance that is produced in the body and obtained from foods that come from animals; it aids in many functions of the body but can become harmful in excessive amounts. As complete LCAT deficiency progresses, the corneal cloudiness worsens and can lead to severely impaired vision.. People with complete LCAT deficiency often have kidney disease that begins in adolescence or early adulthood. The kidney problems get worse over time and may eventually lead to kidney failure. Individuals with this disorder also usually have a condition known as hemolytic anemia, in which red blood cells are broken down (undergo hemolysis) ...

Vascular disease is a feature of aging, and coronary vascular events are a major source of morbidity and mortality in rare premature aging syndromes. One such syndrome is caused by mutations in the lamin A/C (LMNA) gene, which also has been implicated in familial insulin resistance. A second gene related to premature aging in man and in murine models is the KLOTHO gene, a hypomorphic variant of which (KL-VS) is significantly more common in the first-degree relatives of patients with premature coronary artery disease (CAD). We evaluated whether common variants at the LMNA or KLOTHO genes are associated with rigorously defined premature CAD. We identified 295 patients presenting with premature acute coronary syndromes confirmed by angiography. A control group of 145 patients with no evidence of CAD was recruited from outpatient referral clinics. Comprehensive haplotyping of the entire LMNA gene, including the promoter and untranslated regions, was performed using a combination of TaqMan® probes and

The expression of the apolipoprotein A-I (apo A-I) gene was investigated in the myelinating sciatic nerve. Hybridization analysis with an apo A-I cDNA probe obtained from a cDNA library of mRNA isolated from rapidly myelinating chick sciatic nerve indicated that apo A-I coding transcripts increase during development in the chick sciatic nerve in parallel with the increase of myelin lamellae. Substantial apo A-I-like immunoreactivity in chick sciatic nerve homogenates was detected by Western blotting. The amount of antigen increased from the 15-d embryonic stage to 1 d posthatch and then decreased. Two subcellular fractions corresponding to the cytoplasmic compartments were particularly enriched in apo A-I. apo A-I immunoreactivity was also found in highly purified myelin preparations. Immunohistochemical staining provided further evidence for the presence of apo A-I in the endoneurial compartment of the sciatic nerve. Electron microscopic examination of these fractions after negative staining ...
