Progress in ACMG/AMP-adapted guidelines for standardized variant curation in familial hypercholesterolemia

Abstract

Background: - The successes of clinical genetics rely on accurate 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 Resources (ClinGen) consortium approves expert panels to recommend disease-specific guidelines to achieve evidence-based, standardized variant curation practice. Familial Hypercholesterolemia (FH) Working Group: - FH is a prevalent monogenic disorder, affecting ~1/250 individuals; - It is characterized by extreme LDL cholesterol levels and premature atherosclerosis causing cardiovascular disease; - Genetic testing is increasingly offered worldwide as a central part of diagnosis.
