Improving the Detection of Potential Cases of Familial Hypercholesterolemia: Co...
Stevens, Christophe A.T.; Vallejo‐Vaz, Antonio J.; Chora, Joana R.; Barkas, Fotis; Brandts, Julia; Mahani, Alireza; Abar, LeilaBackground: Familial hypercholesterolemia (FH), while highly prevalent, is a significantly underdiagnosed monogenic disorder. Improved detection could reduce the large number of cardiovascular events attributable to poor case finding. We aimed to assess whether machine learning algorithms outperform clinical diagnostic criteria (signs, history, and biomarkers) and the recommended screening criteria in the Unite...
Contemporary Homozygous Familial Hypercholesterolemia in the United States: Ins...
Cuchel, Marina; Lee, Paul C.; Hudgins, Lisa C.; Duell, P. Barton; Ahmad, Zahid; Baum, Seth J.; Linton, MacRae F.; de Ferranti, Sarah D.Background: Homozygous familial hypercholesterolemia (HoFH) is a rare, treatment-resistant disorder characterized by earlyonset atherosclerotic and aortic valvular cardiovascular disease if left untreated. Contemporary information on HoFH in the United States is lacking, and the extent of underdiagnosis and undertreatment is uncertain. Methods and Results: Data were analyzed from 67 children and adults with cli...
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...
Estudo Português de Hipercolesterolemia Familiar: 1999-2020
Medeiros, Ana M.; Alves, Ana C.; Chora, Joana R.; Bourbon, MafaldaA Hipercolesterolemia Familiar (FH) é uma doença genética do metabolismo dos lípidos, para a qual existem métodos de diagnóstico e tratamentos eficazes disponíveis. Em Portugal estima-se que existam entre 20 000–33 000 pessoas com FH (prevalência 1:500–1:300). Indivíduos com FH possuem um elevado risco de desenvolver uma doença cardiovascular prematura (DCV), pois apresentam valores de colesterol elevados desde...
Specification of ACMG AMP Guidelines for Variant Interpretation in Familial Hyp...
Chora, Joana R.; Lacocca, Michael A.; Carrié, Alain; Leigh, Sarah E.; Tichý, Lukáš; Kurtz, C. Lisa; Freiberger, Tomas; Sijbrands, Eric J.Background and Aims: the general ACMG/AMP guidelines for standardized variant interpretation in Mendelian disorders are a great asset in determining variants’ pathogenicity, but need to be adapted to each specific gene and disease.
Genomics of familial hypercholesterolaemia
Alves, Ana C.; Chora, Joana R.; Bourbon, MafaldaFamilial hypercholesterolaemia is an autosomal dominant disorder of lipid metabolism characterized by elevated levels of LDL-C and increased cardiovascular risk. Although the disorder can be diagnosed based on established clinical criteria, only the genetic diagnosis confirms the clinical suspicion. There are three main genes associated with familial hypercholesterolaemia: LDL receptor (LDLR), responsible for m...

Kurtz, C. Lisa; Carrie, Alain; Chora, Joana R.; Iacocca, Michael; Leigh, Sarah; Freiberger, Tomas; Tichy, Lukas; Defesche, Joep; Hegele, RobertFamilial hypercholesterolemia (FH) is a common autosomal dominant disorder (~1:250 individuals affected) of lipid metabolism, associated with an increased risk of cardiovascular disease. Individuals with FH characteristically present with severely elevated blood cholesterol levels, which leads to atherosclerotic plaque formation and subsequently, myocardial infarction due to premature coronary artery disease. T...
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:...
Adaptation of ACMG/AMP guidelines for standardized variant interpretation in fa...
Iacocca, Michael A.; Chora, Joana R.; Freiberger, Tomas; Carrie, Alain; Leigh, Sarah E.; Kurtz, C. Lisa; Tichy, Lukas; DiStefano, Marina T.Background: The successes of clinical genetics rely on accurate DNA variant interpretation for the purpose of informing diagnosis and treatment; However, this practice is often rudimentary and differs among diagnostic laboratories, leading to inconsistencies in pathogenicity classification: In response, the Clinical Genome (ClinGen) Resource consortium approves expert panels to recommend disease-specific guidel...
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.
