Functional characterization of 16 variants found in the LDL receptor gene
Konečná, Kateřina; Přerovská, Tereza; Loja, Tomáš; Fajkusová, Lenka; Koutná, Jana; Kramárek, Michal; Alves, Ana Catarina; Bourbon, MafaldaFamilial hypercholesterolemia (FH) is a disorder of cholesterol metabolism characterized by elevated LDL-cholesterol levels. The most common cause of FH is pathogenic variants in the LDL receptor (LDLR) gene. To shed light on the functional impact of selected LDLR variants, we functionally characterized 16 LDLR genetic variants alongside 10 control variants. We performed in vitro assays based on transient expre...
The Clinical Genome Resource (ClinGen) Familial Hypercholesterolemia Variant Cu...
Chora, Joana R.; Iacocca, Michael A.; Tichý, Lukáš; Wand, Hannah; Kurtz, C. Lisa; Zimmermann, Heather; Leon, Annette; Williams, MaggiePurpose: In 2015, the American College of Medical Genetics and Genomics (ACMG) and the Association for Molecular Pathology (AMP) published consensus standardized guidelines for sequence-level variant classification in Mendelian disorders. To increase accuracy and consistency, the Clinical Genome Resource Familial Hypercholesterolemia (FH) Variant Curation Expert Panel was tasked with optimizing the existing ACM...
The time is now: Achieving FH paediatric screening across Europe – The Prague D...
Bedlington, Nicole; Abifadel, Marianne; Beger, Birgit; Bourbon, Mafalda; Bueno, Héctor; Ceska, Richard; Cillíková, Kristýna; Cimická, ZdenkaFamilial Hypercholesterolaemia (FH) is severely under-recognized, under-diagnosed and under-treated in Europe, leading to a significantly higher risk of premature cardiovascular diseases in those affected. FH stands for inherited, very high cholesterol and affects 1:300 individuals regardless of their age, race, sex, and lifestyle, making it the most common inherited metabolic disorder and a non-modifiable card...
ClinVar database of global familial hypercholesterolemia-associated DNA variants
Iacocca, Michael A.; Chora, Joana R.; Carrié, Alain; Freiberger, Tomáš; Leigh, Sarah E.; Defesche, Joep C.; Kurtz, C. Lisa; DiStefano, Marina T.Accurate and consistent variant classification is imperative for incorporation of rapidly developing sequencing technologies into genomic medicine for improved patient care. An essential requirement for achieving standardized and reliable variant interpretation is data sharing, facilitated by a centralized open-source database. Familial hypercholesterolemia (FH) is an exemplar of the utility of such a resource:...
Familial hypercholesterolemiaassociated variants in ClinVar
Chora, Joana R.; Iacocca, Michael A.; Carrié, Alain; Freiberger, Tomáš; Leigh, Sarah E.; Defesche, Joep C.; Kurtz, C. Lisa; DiStefano, Marina T.Familial Hypercholesterolemia (FH): Lipid metabolism autosomal dominant condition; Patients present elevated low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) values since birth - elevated cardiovascular risk if untreated; High heterozygote prevalence (1/250-500); Homozygous rare (1/300 000-1 000 000); Caused by pathogenic variants in LDLR (>90%), APOB (5-10%) and PCSK9 (1-3%) genes.
