Background: Clinically, Familial Hypercholesterolaemia (FH) is characterized by high plasma concentrations of total and LDL cholesterol from birth, leading to premature atherosclerosis and coronary heart disease. Currently, the genetic diagnosis is made by finding a functional mutation in one of 3 genes: low-density lipoprotein receptor (LDLR ≈ 90-94%), apolipoprotein B (APOB ≈ 5-9%) and proprotein convertase s...
Familial hypercholesterolemia (FH) is a common disorder of lipid metabolism. However there are other rare disorders presenting a similar phenotype as Sitosterolemia, where the patient also presents with high LDL values. Sitosterolemia is a rare autosomal recessive disorder, manifested by extremely elevated plant sterols (PS) in plasma and tissue, leading to xanthomas and premature atherosclerotic disease. This ...
