Diferenças demográficas e clínicas em pacientes com suspeita de hipercolesterolemia familiar: uma análise observacional
Demographic and clinical differences in patients with suspected familial hypercholesterolemia: an observational analysis

Arq. bras. cardiol; 121 (9 supl.1), 2024
INTRODUÇÃO: A hipercolesterolemia familiar (HF) é uma doença autossômica dominante, caracterizada por altos níveis plasmáticos do colesterol de lipoproteína de baixa densidade (LDL-C) e pelo alto risco de desenvolvimento prematuro de doenças cardiovasculares (DCV). OBJETIVO: Avaliar as diferente...

Predicted deleterious variants in ABCA1, LPL, LPA and KIF6 are associated with statin response and adverse events in patients with familial hypercholesterolemia and disturb protein structure and stability

Pharmacogenet. genomics; 34 (4), 2024
OBJECTIVES: This study explored the association of deleterious variants in pharmacodynamics (PD) genes with statin response and adverse effects in patients with familial hypercholesterolemia (FH) and analyzed their potential effects on protein structure and stability. METHODS: Clinical and laboratory dat...

An adapted cardioprotective diet with or without phytosterol and/or krill oil supplement in familial hypercholesterolemia: A pilot study protocol

BACKGROUND AND AIMS: A healthy diet is one of the pillars of familial hypercholesterolemia (FH) treatment. However, the best dietary pattern and indication for specific supplementation have not been established. Our aim is to conduct a pilot study to assess the effect of an adapted cardioprotective diet ...

Interações complexas na hipercolesterolemia familiar: um estudo de caso de aterosclerose multivascular e variantes genéticas
Complex interactions in familial hypercholesterolemia: a case study of multivascular atherosclerosis and genetic variants

INTRODUÇÃO: A hipercolesterolemia familiar (HF) é um distúrbio genético bem reconhecido que se manifesta como níveis significativamente elevados de LDL-c sérico devido a aberrações no metabolismo das lipoproteínas. A maioria dos casos de HF, especificamente 85-90%, está associada a mutações ...

Effects of LDLR variants rs5928, rs750518671 and rs879254797 on protein structure and functional activity in HepG2 cells transfected with CRISPR/Cas9 constructs

Gene; 890 (), 2024
Familial Hypercholesterolemia (FH) is a genetic disorder associated with premature atherosclerosis and increased risk of cardiovascular diseases. LDLR deleterious mutations are associated with FH, however the role of some missense variants in FH pathogenicity remains to be elucidated. This study explored...

Lipidomic analysis identified potential predictive biomarkers of statin response in subjects with Familial hypercholesterolemia

Chem. Phys. lipids; 257 (), 2023
Familial hypercholesterolemia (FH) is a disorder of lipid metabolism that causes elevated low-density lipoprotein cholesterol (LDL-c) and increased premature atherosclerosis risk. Statins inhibit endogenous cholesterol biosynthesis, which reduces LDL-c plasma levels and prevent from cardiovascular events...

LDLR and PCSK9 3´UTR variants and their putative effects on microRNA molecular interactions in familial hypercholesterolemia: a computational approach

Mol. Biol. reports; 50 (), 2023
BACKGROUND Familial hypercholesterolemia (FH) is caused by pathogenic variants in low-density lipoprotein (LDL) receptor (LDLR) or its associated genes, including apolipoprotein B (APOB), proprotein convertase subtilisin/kexin type 9 (PCSK9), and LDLR adaptor protein 1 (LDLRAP1). However, approximately 4...

In silico analysis of upstream variants in Brazilian patients with familial hypercholesterolemia

Gene; 849 (146908), 2023
ABSTRACT: Familial hypercholesterolemia (FH) is a prevalent autosomal genetic disease associated with increased risk of early cardiovascular events and death due to chronic exposure to very high levels of low-density lipoprotein cholesterol (LDL-c). Pathogenic variants in the coding regions of LDLR, APOB...

LDLR missense variants disturb structural conformation and LDLR activity in T-lymphocytes of familial hypercholesterolemia patients

Gene; 853 (147084), 2022
ABSTRACT: Familial hypercholesterolemia (FH) is caused by deleterious mutations in the LDLR that increase markedly low-density lipoprotein (LDL) cholesterol and cause premature atherosclerotic cardiovascular disease. Functional effects of pathogenic LDLR variants identified in Brazilian FH patients were ...

Effects of PCSK9 missense variants on molecular conformation and biological activity in transfected HEK293FT cells

Gene; 851 (146979), 2022
ABSTRACT: PCSK9 gain-of-function (GOF) variants increase degradation of low-density lipoprotein receptor (LDLR) and are potentially associated with Familial Hypercholesterolemia (FH). This study aimed to explore the effects of PCSK9 missense variants on protein structure and interactions with LDLR using ...
