Cosegregation of serum cholesterol with cholesterol intestinal absorption markers in families with primary hypercholesterolemia without mutations in LDLR, APOB, PCSK9 and APOE genes.

Abstract excerpt

BACKGROUND AND AIM: The genetic cause and pathogenic mechanism of approximately 20-40% of autosomal dominant hypercholesterolemias (ADH) are unknown. Increased cholesterol intestinal absorption has been associated to ADH. If this variation contributes to their pathogenesis is unknown. METHODS AND RESULTS: We studied cholesterol absorption (phytosterols and cholestanol serum concentrations) and cholesterol...
