Background: Homozygous familial hypercholesterolemia (HoFH) is a severe form of familial hypercholesterolemia (FH), characterized by high low-density lipoprotein cholesterol (LDL-C) levels and increased coronary artery disease risk. This study reports a novel Alu insertion in the LDLR gene in a consanguineous Indian family, causing FH.
Objective: To identify and characterize the mutation causing HoFH in a proband and their family members.

Importance: Disease characteristics of genetically mediated coronary artery disease (CAD) on coronary angiography and the association of genomic risk with outcomes after coronary angiography are not well understood.
Objective: To assess the angiographic characteristics and risk of post-coronary angiography outcomes of patients with genomic drivers of CAD: familial hypercholesterolemia (FH), high polygenic risk score (PRS), and clonal hematopoiesis of indeterminate potential (CHIP).
Design, Setting, And Participants: A retrospective cohort study of 3518 Mass General Brigham Biobank participants with genomic information who underwent coronary angiography was conducted between July 18, 2000, and August 1, 2023.

Introduction: LDL-cholesterol greater than 190 mg/dL indicates severe hypercholesterolemia (HS) of monogenic and/or polygenic origin. Genetic risk scores (GRS) evaluate potential polygenic causes.
Objective: we applied a GRS of 6-SNP (GRS-6) in HS individuals.

Cholesterol ester storage disease (CESD) is a rare autosomal recessive lysosomal storage disorder caused by mutations in the LIPA gene, leading to reduced lysosomal acid lipase activity, cholesterol ester accumulation, and systemic manifestations including liver dysfunction and dyslipidemia. We report the case of a 25-year-old male presenting with subacute jaundice, hyperbilirubinemia (total bilirubin 51 mg/dL, predominantly direct), and dyslipidemia characterized by elevated total cholesterol and low HDL cholesterol levels. Initial diagnostic workup for acute hepatitis and liver dysfunction, including serological and imaging studies, was unremarkable.
